ТЕКСТ 10А

HARMONY WITH ENVIRONMENT

Minerals at shallow depths are extracted by open-cast mining which is cheaper than underground mining. Open-cast mining consists in removing the overburden, and other strata that lie above mineral or fuel deposits to recover them.

Opencastsor open-pit mines are in fact quarries for getting coal or metalliferous minerals. In the USA opencasts are called strip mines (strip pits).

All the surface excavations, waste heaps and equipment needed for extracting mineral in the open form an independent mining unit. An opencast is a long, wide and comparatively shallow working though it can reach 200 m or even more in depth.

Fig. 10, Open-cast working

In opencasts the excavation is by horizontal slices corresponding to the type of mineral or overburden in slice. In Fig. 10 one can see the benches (or slices). A bench is a thickness of rock or mineral which is separately broken or excavated. Other open workings are called trenches, which are long, narrow, shallow exploratory workings.

The whole production

process in

opencasts can be

divided

into the following basic

stages: 1)

preparing the site to

be

worked; 2) dewatering it

and preventing inflows of

water

to

the site; 3) providing access (entry) to the deposit by the necessary permanent investment; 4) removal of overburden (stripping); 5) mineral excavation.

Stripping the overburden and mineral production include breaking rock or mineral, transporting it and loading it.

Minerals can often be dug directly by earth-moving equipment while to break hard rocks it is necessary to use explosives.

Modern methods of working opencasts involve the use of

mechanical

plants or hydraulicking. The basic units of a

mechanical

plant are excavators, car drills or other

mounted

drills, and

various mechanical handling equipment

whereas

the basic units of hydraulicking are monitors, pumps such as sludge pumps or gravel pumps. Hydraulicking can be used in soft or friable ground.

Transport operations involve the removal of waste rock

2QH

or mineral, the latter being transported

to coal

washeries,

ore concentration plants, to power stations, or to a railway

station. Waste rock is removed to a spoil

heap or

dump (tip)

either outside the deposit or in an extracted area; these being called external or internal dumps, respectively.

The transport used in opencasts are rail cars, large lorries, and conveyers. Sometimes the overburden is stripped and dumped by excavators without other transport, in overcasting or sidecasting.

Mineral is usually unloaded at specially equipped permanent stations. Waste rock is dumped at various points which are moved as the work develops.

Summing up, mention should be made of the fact that last decades have seen a marked trend towards open-cast

operations.

Large

near-surface (though usually

low-grade)

deposits offer

the

possibility of achieving greater outputs.

There can

be

little

doubt that the cost per ton of

ore mined

by underground methods is generally higher than that for open-cast mining.

At the same time it is necessary to say that although efforts are made to develop mine sites in harmony with the environment, extraction methods produce some disturbances on the Earth's surface which reduce its economic value. In recent years the USSR and other countries have developed national programmes for environmental protection. The aim of such programmes applicable to the mining industry is to control and protect natural resources and regulate reclamation and landscape restoration.

1. Mineral reserves suitable (пригодный) for open-cast mining in the USSR are concentrated mostly in the eastern areas, with only small per cent of them being found in the European part, including the Ural Mountains. 2. The discovery of such deposits as coal, shale, iron, manganese, salts, sulphur, etc. is facilitated by their considerable dimensions and relatively large aerial distribution, the detection of con - cealed (скрытый) deposits being very much more difficult. 3. The most widely used hydraulic method of mining involves the use of water jets (струя), this method being increasingly used, both underground and in quarries. 4. The type of power which drives mining machines can be either electricity or compressed air, most mining machines in the USSR being electrically driven. 5.

ORE MINING

 

 

 

 

 

 

As

has

already

been said mining is a

branch of industry

which

deals

with

the recovery of valuable minerals

from

the interior

of

the Earth.

 

 

When minerals occur so that they can be worked at a profit, they are called ore deposits. Economic minerals are those which are of economic importance and include both metallic (ore minerals) and non-metallic minerals such as building materials (sand, stone, etc.).

In choosing the methods of working ore deposits one must take into consideration the following main factors: 1) the

shape of the deposit; 2) the dimensions of the

deposit in

thickness, along the strike and

down

the dip;

3)

the type

of ore and the distribution of metal

in the

ore

body.

The shape of the ore deposit

affects the

mining

method.
