Extraction of building stone

Mining actually means extracting all kinds of rocks such as building stones and valuable minerals. Also, other geological materials are from deposits or deposits in the ground that are usually extracted from ores, veins, joints or cracks, rocks or plaques. These reserves form a significant product and economic resource for miners.

Mine obtained from the mine includes metals, coal, sand, petroleum clay, precious stones, limestone, gypsum, salt, potash, sand and clay. To obtain any material that can not be obtained in the laboratory or factory through agricultural processes. Mining is required.

Mining in a broader sense involves extracting non-renewable resources such as oil, natural gas or even water. Mining methods are:

The four main methods of extracting mines and building stones are as follows:
Underground, open surface (pit), placer and on-site extraction
Underground mining typically involves higher costs and is often used to achieve deeper reserves.
Surface mining is usually done for less valuable and deeper resources.
Placer extraction is a method used by river canals, coastal sands or other environments to capture precious and heavy metals from sediments.

On-site mining, primarily used in the uranium mine, involves dissolving a mineral resource deep in the ground and then processing it on the surface, without having to move the rock off the ground.

Porcelain Mining and Building Stone Techniques
Surface extraction means the removal of surface vegetation, soil and, if necessary, layers of the bed to reach the buried heavy sediments. Surface extraction methods are:

Open pit mining, which is the recycling of materials from an open pit in the ground. Building stone and ore are mainly mined by pit method.
The strip extraction method involves separating the surface layers to reveal the ore in the underlying layers.
The method of mountain removal, which is usually done to extract coal, involves removing the top of the mountain to reach deep rock deposits.

Underground extraction of building stone

Subsurface mining involves drilling into ground tunnels or shafts to obtain buried and hidden building stone and ore deposits. The ore is brought to the surface through tunnels and shafts for processing and removes unused and excess rocks. They bring it out.

Subsurface extraction can be classified according to the type of shafts used, the extraction method or the techniques used to reach the underground reserves.

Thrust extraction is made using available horizontal tunnels. For slope extraction, diagonally accessible shafts are used diagonally and shaft extraction uses available vertical shafts. Mining in hard and soft rock structures and textures requires different techniques. has it.

Extraction of high walls of Crystal stone

High wall mining is another surface mining method that has evolved from drilling or ogging. A type of extraction driven by a push-pull hydraulic transmission mechanism (PTM) that penetrates the coal gap. A typical cycle involves pouring (throwing forward) and cutting (raising and lowering the cut to reduce the total The height of the coal seam).
