Since the mineral occurs in definite veins, a more satisfactory and economical method of working would be that adopted in metalliferous mines, with a vertical shaft, cross-cuts, and levels running along the strike of the vein: the mica could then be extracted by overhead stopping, and the waste material used for filling up the worked-out excavations.

Finally, to enable them to work their mines to their full capacity, the Rand houses asked for leave to import Chinese labourers.'

The latter includes not only the actual excavation of the mineral, but also haulage and hoisting by which it is brought to the surface, timbering and other means of supporting the excavations, and the drainage and ventilation of mines.
In coal mines, entries and headings, bords and walls serve similar purposes.
In the early history of mining there was but little attempt at systematic development and working, and the mines were often irregular and tortuous.
In such mines the mineral was carried out on the backs of men, and the water was laboriously raised by a long line of suction-pumps, operated by hand, each lifting the water a few feet only.
In shallow mines the pillars are small and the saving of the mineral of minor importance.
In deep mines the pillars may furnish the bulk of the product, and the control of the fall of the roof, so as to permit the successful extraction of the mineral, demands a well-schemed plan of operation.
If rock-filling must be brought from the surface its use will generally be confined to mines in which it is difficult to support the roof in any other way.
This method originated in the Pennsylvania anthracite mines in 1887, but has been employed in recent years on a large scale in Silesia, Westphalia and other European coalfields.
In the United States cars in the coal and iron mines hold from 2 to 4 tons.
In mines of copper, lead and the precious metals, in which the cars are moved by hand, the usual load is from 1200 to 3000 lb.
In metal mines, where, as a rule, mechanical haulage is inapplicable, the cars are moved by men (trammers).
Animal haulage is employed chiefly in collieries and large metal mines; sometimes for main haulage lines, but oftener for distributing empty cars and making up trains for mechanical haulage.
Locomotive haulage is applicable to large mines, where trains of cars are hauled long distances on flat or undulating roads of moderate gradients.
(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.
Fixed drums are best for mines in which the hoisting is done chiefly from one level; independent drums when there are a number of different levels.
Allis and silver mines.
In shallow mines the men use the ladder-way in going to and from their work.
At mines with vertical shafts this is a simple operation.
Cages of the size generally used in metal mines will hold from ten to fifteen and occasionally twenty men.
These are common in Europe, and are sometimes employed in the United States and elsewhere in mines where the output is large and the shafts deep and of small cross section.
Nevertheless, in very deep and large mines the time consumed in handling the men may make serious inroads on the time available for hoisting ore.
At a few mines special man-cages are operated in separate compartments by their own engines for handling part of the men, and for tools, supplies, &c. For inclined shafts, where the mineral is hoisted in skips, the operation of raising and lowering men may not be so simple.
At a few mines (since safety catches cannot be successfully applied to man-cars) these conveyances are raised and lowered by separate engines and ropes.
Formerly, at many deep European mines, and at a few in the United States, men were raised by means of " man-engines."
In coal mining the market demand varies in different seasons, and surface storage is sometimes necessary to permit regular work at the mines.
Water may be raised from mines by buckets, tanks or pumps.
(3) For clearing flooded mines.
Cornish pumps are the oldest of the machines for draining mines; in fact, one of the earliest applications of the old Woolf and Newcomen engines in the 18th century was to pumps for deep mines.
For example, carbon dioxide occurs in some mines, and hydrogen sulphide, which is a poisonous gas, in others.
Very large volumes of air are necessary for this purpose, so that in such mines other sources of vitiation are adequately provided against and need not be considered.
In metal mines, however, artificial ventilation is rarely attempted, and natural ventilation often fails to furnish a sufficient quantity of air.
The examination of the air of metal mines has shown that in most cases it is much worse than the air of crowded theatres or other badly ventilated buildings.
The efficiency of such ventilating furnaces is low, and they cannot safely be used in mines producing fire-damp. They are sometimes the cause of underground fires, and they are always a source of danger when by any chance the ventilating current becomes reversed, in which case the products of combustion, containing large quantities of carbon dioxide, will be drawn into the mine to the serious danger of the men.
Positive blowers and exhausting apparatus of a great variety of forms have been used in mines for producing artificial ventilation.

In the Alpine tunnels, where the air was moist and probably not as pure as in the Comstock mines, great difficulty was experienced in prosecuting the work at temperatures of 90° F.
Deep mines, however, are generally dry, so that in most cases it will be possible to realize the more favourable conditions of the Comstock mines.
In many deep mines to-day " explosive rock " has been encountered.
A similar condition of strain has been observed in deep mines in different parts of the world - perhaps due to geological movements.
Similar swelling ground is not infrequently met with in metal mines, as, for example, in the Phoenix copper mine in Houghton county, Michigan, where the force developed was sufficient to crush the strongest timber that could be used.
In very deep mines this flowing of soft rock will doubtless add greatly to the difficulty of maintaining openings.
These simple business principles do not seem to be generally recognized by the investing public, and mines, whose earning capacity is accurately known, are frequently quoted on the stock markets at prices which cannot possibly yield enough to the purchaser to repay his investment during the probable life of the mine.
The valuation of mines then involves the following steps: (1) The sampling of the deposit so far as developed, and assaying of the samples taken; (2) The measurement of the developed ore; (3) estimates of the probable amount of ore in the undeveloped part of the property; (4) estimates of probable profits, life of the mine, and determination of the value of the property.
On the other hand in the case of uncertain and irregular deposits, the value of which varies between very wide limits, as, for example - in most metal mines and especially mines of gold and silver - a very large number of samples must be taken - sometimes not more than two or three feet apart - in order that the average value of the ore may be known within reasonable limits of error.
For the purpose of training such men special schools of mining engineering (ecoles des mines, Bergakademie) have been established in most mining countries.

In the metal mines of Cornwall and Devon special rules are now in force requiring the use of water in drilling, and other precautions, to lessen this danger from dust.
In some mines dust seems to have but little effect on the health of the miners; indeed it is even claimed by some that coal dust decreases the mortality from phthisis.
The climbing of ladders from deep mines not only lessens the efficiency of the men by reason of fatigue, but often tends to increase the mortality from diseases of the heart.
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.
