to Constance, Lady Despenser, in September 1403, but it was shortly afterwards taken by Owen Glyndwr, to whose mining operations tradition ascribes the leaning position of a large IV.
Mining is now the chief industry of the district.
The mineral resources include silver, gold, copper, lead, tin, iron and coal, and mining is the chief industry.
DIAMANTINA (formerly called Tejuco), a mining town of the: state of Minas Geraes, Brazil, in the N.E.
It is the terminus of some important narrow-gauge mining railways and steam tramways, which place it in communication with the mining districts of Guipuzcoa and Navarre, and with the valuable oak, pine and beech forests of both provinces.
MINING, the general term for the working of deposits of valuable mineral.
The term 1 is not limited to underground operations, but includes also surface excavations, as in placer mining and open-air workings of coal and ore deposits by methods similar to quarrying, and boring operations for oil, natural gas or brine.
Mining may be subdivided into the operations of prospecting or search for minerals, exploration and development, work preparatory to active operations, and working.
Finally, under the heads of administration, mine valuation, mining education, accidents, hygiene and mining law, will be discussed matters having important bearing on mining operations.
Special methods of mining are dealt with in the separate articles on Coal, Gold, and other minerals and metals.
Quarrying and ORE-Dressing, which may be considered as branches of mining, are also discussed in separate articles.
Work undertaken to secure this information must be distinguished from prospecting, which is the search for mineral deposits and from development, work undertaken to prepare for actual mining operations.
The risk of failure in mining enterprises is offset by the chances of more than ordinary profits.
By sinking additional pits or by extending the costeaning trenches and uncovering the outcrop of the deposit more fully it is sometimes possible to obtain all the information required for the most extensive and important mining operations.
In the case of such altered deposits surface exploration alone is likely to be misleading, and it is important to push the underground exploration far enough to reach the unaltered part of the deposit, or at least deep enough to make it certain that there is a sufficient quantity of altered or enriched ore to form the basis of profitable mining operations.
The money so spent, if judiciously used, insures the undertaking against loss by diminishing the mining risk, and is thus analogous to premiums paid to insure against fire or other sources of loss.
As soon as it appears reasonably certain that the property is workable the mine will be opened by one or more shafts, drifts or tunnels, and the underground passages for active mining operations will be started.
Drifts, entries and tunnels find their chief application in mining regions cut by deep valleys.
In metal mining, when the workable portions of the deposit are small and separated by unworkable areas, the levels serve also the purpose of exploration, and in such cases must not be so far apart as to risk missing valuable mineral.
In irregular and uncertain deposits this work of development should be kept at all times so far in advance of mining operations as to ensure a regular and uniform output.
A mine, however, may be over-developed, which results in loss of interest on the capital unnecessarily locked up for years by excessive development, and involves additional cost for the maintenance of such openings until they are needed for active mining operations.
The method, of mining adopted must secure the extraction of the mineral at a minimum cost.
The principal item in mining cost is that of labour, which is expended chiefly in breaking down the mineral, either by the use of hand tools or with the aid of powder.
While the width of the working-place is thus limited by the strength of the roof, its length is determined by other considerations - namely, the rapidity with which the mining work can be conducted and the length of time it is practicable to keep the working-place open, and also by the increased difficulty of handling the minerals sometimes experienced when the workings reach undue length.
In long-wall and in the work of mining pillars the roof will be supported on one side only, the overhanging beds acting as cantilevers.
In the early history of mining there was but little attempt at systematic development and working, and the mines were often irregular and tortuous.
With but slight modifications permitting the use of pumps and hoistingmachinery equally simple methods of mining may be seen to-day when the deposit is of small extent.
In the systematic mining of larger deposits, the simplest plan consists in mining large areas by means of numerous working-places under the protection of pillars of mineral left for the purpose, and later mining these pillars systematically, allowing the overlying rock beds to fall and fill the abandoned workings.
In this method of mining the different stopes must be kept close together; otherwise there is much added labour in shovelling the broken ore down to the main level.
This method of mining requires but little timbering, FIG.
In this method of mining no pillars need be left under the levels, as the rock-filling gives sufficient support to the roof.
This method of mining affords the maximum of safety to the miners.
This mat of timber forms a roof under the protection of which the mining of the ore proceeds downward floor by floor.
These separate areas are then mined in small rooms, each room being timbered as in mining under a weak roof rock.
Before abandoning a room it is usual to cover the bottom of the working-place with laggingpoles, which facilitate the mining of the floor below.
The mining of each floor is carried on in sections with small working-places which are first driven of moderate height to their full length and width, leaving a back of ore above and pillars of ore between to support the upper portion of the upper layer or floor.
The bottom-slice caving system of mining begins at the bottom of a hundred-foot block of ground, a floor being excavated under the whole area, leaving pillars of sufficient size to support the ground above.
When rock filling is available, as when the ore contains much barren material to be left behind in mining, the ore body is divided into blocks of convenient height as above, and these blocks are divided into floors, the bottom floor of each block however being attacked.
Instead of mining in horizontal floors the filling method permits the ore to be mined in vertical chambers or slices which extend from one level to the next above and from one wall of the deposit to the other.
This method of mining and filling can be used when the work is done in horizontal floors or in transverse chambers.
The use of the heavy timbers and continuous framing which characterize this system facilitates greatly the work of mining and maintaining the haulage roads on the different floors, and gives more rigid support to the unmined portions of the block of ground above.
Examples of other mining methods will be found under Coal.
'Where mineral deposits lie near the surface underground mining may be replaced by open excavations, and the reduced cost of mining makes it possible to remove the overlying soil and rock to considerable depths.
The cost of mining by the milling method does not greatly exceed the cost of steam-shovel work.
(For details see Hughes, Text-book of Coal Mining, pp. 236-272; Hildenbrand, Underground Haulage by Wire Rope.) Rope haulage is widely used in collieries, and sometimes in other mines having large lateral extent and heavy traffic. With the tail-rope system, cars are run in long trains at high speed, curves and branches are easily worked, and gradients may be steep, though undulating gradients are somewhat disadvantageous.
Steel frames are more durable than those of wood, and have become common in nearly all mining countries, especially where timber is scarce.
- Ore and water skips mining cage and car for gold for inclined shaft.
Man-engines were long used, but are now practically abandoned in both Great Britain and the United States, and few remain in any of the mining regions of the world.
In mining regions where 'water transportation is interrupted during certain months of the year the mineral must be stored underground, or in great stock-piles on the surface.
In coal mining the market demand varies in different seasons, and surface storage is sometimes necessary to permit regular work at the mines.
In many mining regions long tunnels have been driven at great expense to secure natural drainage.
Under modern mining conditions drainage tunnels have lost much of their former importance.
Taking into account the risk attending all mining operations, which make necessary large interest and amortization charges on the cost of a tunnel, it will in most cases be advisable to raise the water to the surface by mechanical means.
In mining operations explosives are used on a large scale and the powder gases contain large quantities of the very poisonous gas, carbon monoxide, a small percentage of which may cause death, and even a minute percentage of which in the air will seriously affect the health.
This has a serious effect on the health and efficiency of the workmen employed, and in extreme cases may even result in increased cost of mining operations.
Two compartments of a shaft may be utilized for this purpose, but greater safety is ensured by two separate openings, as required by law in most mining countries.
There has been much speculation as to the depth to which it will be practicable to push the work of mining.
The special difficulties which attend deep mining, in addition to the problems of hoisting ore and raising water from great depths, are the increase of temperature of the rocks and the pressure of the overlying strata.
The possibility of hoisting and pumping from great depths has been discussed, and it remains now to consider the other conditions which will tend to limit mining operations in depth - namely, increase of temperature and increase of rock pressure.
In the Comstock mines at Virginia City, Nevada, it is possible to continue mining operations at rock temperatures of 130° F.
It is apparent that the combined effect of internal heat and rock pressure will greatly increase the cost of mining at depths of 8000 or 10,000 ft., and will probably render mining impracticable in many instances at depths not much greater.
In organizing a mining company it must be recognized that mining is of necessity a temporary business.
Mining is also subject to the risks of ordinary business enterprises, and to additional risks and uncertainties peculiar to itself.
In addition mining operations are subject to interruption and added expense from explosions, mine fires, flooding, and the caving-in of the workings.
To provide for the repayment from earnings of the capital invested in a mining property and expended in development, and to provide for the depreciation in value of the plant and equipment, an amortization fund must be accumulated during the life of the mine; or, if it be desired to continue the business of mining elsewhere, a similar fund must be created for the purchase, development and equipment of a new property to take the place of the original deposit when that shall be exhausted.
To cover the special risks of mining, capital should earn a higher interest than in ordinary business, and if we assume that the sinking-fund be safely invested, we must compute the amortization on a lower basis than 5%.
In the case of mining properties these profits are more or less uncertain, and cannot be accurately determined until the deposit has been thoroughly explored and fully developed.
In many instances, indeed, profits are more or less uncertain during the whole life of the mine, and it is evident that the value of the mining property must be more or less speculative.
Further, both time and money are required for the development of the mining property before any profit can be realized.
In order to determine the probable profit and life of the mine a definite scale of operations must be assumed, the money required for development and plant and for working capital must be estimated, the methods of mining and treating the ore determined, and their probable cost estimated.
It is necessary to have the work directed by men thoroughly familiar with the characteristics of mineral deposits, and with wide experience in mining.
For the purpose of training such men special schools of mining engineering (ecoles des mines, Bergakademie) have been established in most mining countries.
A student of mining must receive thorough instruction in geology; he must study mining as practised in different countries, and the metallurgical and mechanical treatment of minerals; and he should have an engineering education, especially on mechanical and electrical lines.
These miners' schools (Bergschule, ecoles des mineurs) give elementary instruction in chemistry, physics, mechanics, mineralogy, geology and mathematics and drawing, as well as in such details of the art of mining as will best supplement the practical information already acquired in underground work.
The training of a mining engineer merely begins in the schools, and mining graduates should serve an apprenticeship before they accept responsibility for important mining operations.
Mining is an extra-hazardous occupation, and the catastrophes, which from time to time have occurred, have caused agencies to enforce their authority.
While in some cases these laws are unnecessarily stringent and tend to restrict the business of mining yet on the whole they have had the effect of reducing greatly the loss of life and injuries of miners where they have been well enforced.
In some mining districts the coal is liable to spontaneous combustion.
Under favourable conditions mining may be conducted under the protection of a few yards of solid rock only, as in the submarine work for the removal of reefs in the harbours of San Francisco and New York.
At Silver Islet, Lake Superior, mining was successfully carried on for years under the protection of a coffer dam and an arch of rich silver ore less than 20 ft.
When large areas are undermined, as in submarine coal mining, it is best to have several hundred feet of protecting rock.
The history of mining is full of dramatic episodes of this character.
The conditions under Accidents which explosives may be stored, handled and used are from carefully formulated in the mining laws of most states, fro Explosives.
While mining is not necessarily an unhealthy occupation, miners are subject to certain diseases resulting from vitiated air, and from unusual or special conditions under which at times they are forced to work.
This seems to be due to the dust abundantly produced in mining operations, and especially by machine drills when boring " dry " (rising) blast holes.
On the other hand, as in mining ores containing lead, arsenic and mercury, the dust may be poisonous.
Ankylostomiasis is a disease which finds a congenial habitat in the warm damp atmosphere of mines, and has become a veritable scourge in some mining regions.
- Mine law is that branch of the law of real property relating to mineral and mining rights as distinct from rights pertaining to the surface of the ground.
Under the common law the owner of the surface possesses all mining rights as well, unless these have been reserved by some previous owner of the property.
This has been recognized from the earliest times, and laws have been framed in all countries for the encouragement of mining enterprise.
In many cases the state or the ruler has sought to obtain a share in the profits of mining, or even to work mines for the individual profit of the ruler or of the state.
But in most cases it has been found better policy for the state to divest itself of all interest in mining property, and to extend all possible encouragement to those who undertake the development of the mineral wealth of the nation.
The mining laws of most civilized states grant the right of free prospecting over the public lands, protect the rights of the discoverer of the mineral deposit during the period of exploration, and provide for the acquisition of mineral property on favourable terms. Striking examples of the far-reaching effect of such laws is shown in the history of the Rocky Mountain region and western coast of the United States, the colonization and development of Australia, and the development of Alaska.

The longer Christina ruled, the more anxious for the future fate of her empire grew the men who had helped to build it up. Yet she gave fresh privileges to the towns; she encouraged trade and manufactures, especially the mining industries of the Dales; in 1649 she issued the first school ordinance for the whole kingdom; she encouraged foreign scholars to settle in Sweden; and native science and literature, under her liberal encouragement, flourished as they had never flourished before.
The province contains gold, silver, copper, iron, lead, coal and salt, but mining has never been developed to any extent.

There was a great development in the mining industry during 18 971898 and 1899, thei value of the gold extracted in 1898 exceeding £15,000,000, but the political situation grew worse, and in September 1899, owing to the imminence of war between the Transvaal and Great Britain, the majority of the Uitlanders fled from the city.
This decrease was largely caused by the practical suspension for many years of the hydraulic mining operations, in preparation for which millions of dollars had been expended in deep tunnels, flumes, &c., and the active continuance of which might have been expected to yield some £2,000,000 of gold annually.
On the other hand, the progressive reduction of mining and metallurgical costs effected by improved transportation and machinery, and the use of high explosives, compressed air, electric-power transmission, &c., resulted in California (as elsewhere) in a notable revival of deep mining.

By far the most important addition to the Australasian product has come fromWestAustralia,which began its production in 1887 - about the time of the inception of mining at Witwatersrand ("the Rand") in South Africa-and by continuous increase, which assumed large proportions towards the close of the 19th century, was £6,426,000 in 1899, £6,179,000 in 1900, and L8,212,000 in 1905.
So certain is the ore-bearing formation that engineers in estimating its auriferous contents feel justified in assuming, as a factor in their calculations, a vertical extension limited only by the lowest depths at which mining is feasible.
Mining and Metallurgy.
In alluvial deposits the richest ground is usually found in contact with the "bed rock"; and, when the overlying cover of gravel is very thick, or, as sometimes happens, when the older gravel is covered with a flow of basalt, regular mining by shafts and levels, as in what are known as tunnel-claims, may be required to reach the auriferous ground.
- This method is employed to extract gold from both alluvial and reef deposits: in the first case it is combined with " hydraulic mining," i.e.
Hydraulic mining has for the most part been confined to the country of its invention, California, and the western territories of America, where the conditions favourable for its use are more fully developed than elsewhere - notably the presence of thick banks of gravel that cannot be utilized by other methods, and abundance of water, even though considerable work may be required at times to make it available.

Nor was the concentration of wealth the only danger of this policy; it led to the destruction of forests, the exhaustion of farming soils and the wasteful mining of coal and minerals, since the desire for quick profits, even when they entail risk to permanency of capital, is always a powerful human motive.
The country is divided into four mining districts: Freiberg, where silver and lead are the chief products; Altenberg, where tin is mainly raised; Schneeberg, yielding cobalt, nickel and ironstone; and Johanngeorgenstadt, with ironstone and silver mines.

The development of the coal and iron interests, and the increasing importance of the gold product of the Appalachian auriferous belt, and also of the lead product of the Mississippi Valley, led to a more general and decided interest in geology and mining; and about 1830 geological surveys of several of the Atlantic states were begun, and more systematic explorations for the ores of the metals, as well as for coal, were carried on over all parts of the country then open to settlement.
Here explorations for copper immediately began, and for the first time in the United States the business of mining for the metals began to be developed on an extensive scale, with suitable appliances, and with financial success.
The total production of coal from 1814 (the year in which anthracite was first mined in Pennsylvania) to 1908 amounted to 7,280,940,265 tons, which represented an exhaustionadding 50% for waste in mining and preparationof 11,870,049,900, or four-tenths of I% of the supposed original supply.
