The invention relates to the mining industry and can be applied in underground mining of stratal mineral deposits, mainly dp coal seams with a capacity of 1.5-2 m.

There is a method of underground mining of coal seams, which includes opening the reservoir with a well drilled from the surface, lowering a distandonic controlled robot with a excavation body, such as a hydromonitor, carrying out rising production through the reservoir, digging coal by distributing this output during the return stroke of the robot and hydraulic transport broken coal to surface 1

However, this method requires significant capital expenditures with a small amount of production and large losses of coal in the subsoil.

There is also known a method of underground mining of stratum mineral deposits, including carrying out vertical shafts, dividing a mine floor into blocks by contouring preparatory workings, working out each block with clearing holes С 2,

However, this underground method. The development of plastov mineral deposits is ineffective.

The purpose of the invention is to increase the efficiency of underground mining by reducing the cost of commissioning the field.

The goal is achieved by the fact that, according to the method of underground mining of reservoir mineral deposits, including the installation of vertical shafts, dividing the mine floor into blocks by contouring the preparatory workings, working out each block by clearing holes, the vertical trunks are spent one in each block at the lower boundary of each the block in its middle part, with this, each block is tested deserted in descending order in strips from the block boundaries to the center.

The method is as follows.

A mine field having one or a formation of several layers is divided into separate excavation blocks. The opening of the working horizons is carried out separately for each block by a single trunk, which is positioned at the lower edge of the reservoir along the block boundary in its middle part. In the presence of a suite of layers, each block will have a number of horizons, equal to the number of layers being developed, and all of these horizons will be revealed with one barrel.

Blocks work out long strips (pillars) with a one preparatory development between them. The strips are worked back by short clearing holes on the formation. It is also possible to work out stripes in the fall. Each block is contoured on the upper and lower borders by preparatory workings (drifts) and split furnaces on the lateral boundaries. At the same time, a central rising preparatory train runs from the trunk, from which the excavations pass.

Using the proposed method will improve the efficiency of development by reducing the cost of putting the field into operation.
