Description

PICTURE: The relation of the mining industry to the field of mining and can be used in the mining of mineral deposits with laying using self-propelled equipment.

Limeon is a method of mining ore bodies by laying with the use of self-propelled equipment, in which the latter is delivered to the layers in specially mined workings 1.

The disadvantage of this method is the need to drill special workings for the delivery of self-propelled equipment to the layers.

There is also a known method for developing steeply dipping vein deposits in horizontal layers from the bottom upwards with laying the developed space and using self-propelled equipment fed into the cleaning space at an inclined exit 2.

The disadvantage of this method of development is the low efficiency of mining operations, due to the large amount of preparatory-rifled works.

The purpose of the invention is to increase the efficiency of mining due to the reduction in the volume of preparatory rifled workings.

This is achieved by the fact that in the course of the clearing recess within the block, the inclined congress forms its contour at an angle that ensures the movement of the self-propelled equipment, and use the backfill array as part of the congress ground during the laying of the working area.

In the drawing, an ore body incision is drawn along the bend.

Preparation and cutting of the excavation site

(block) is carried out by conducting a haul 1 and a vent 2 shtracks and backfill risers 3.

The breaking of ore in the layer is made by rising. or horizontal shary charges. Repulsed ore 4 G1Gr. Of the transport and delivery system will be transported to the b ore, issued in tab 7. The bookmark will be refined, the volume of the block is followed by the removal of broken ore. At completion

Laying a layer on its flank form a slope at an angle, which ensures the movement of self-propelled equipment to it, forming the night of an inclined ramp 8 on the haulage drift 1. The roof of the next layer is beaten off

in accordance with the profile laid bookmarks.

Inclined congress 9, formed during the development of the previous section, is redeemed with layer-by-layer BOzVEDE: H1 and bookmarks, and layer by layer

Claims (2)

The developed oblique congress 8 leads to the ventilation drift 2 parallel to the redeemed congress 9. When using the proposed method of field development, there may be several blocks in the work, a single T1 transport channel with a haulage n drift. With the approach of cleaning works to the flank of the field and layer-by-layer mining of the block from the bottom up, the slope on the haulage drift is repaid by placing it together with the layer, saving only the vent drift. The introduction of the proposed method will allow the juice to be prepared. The volume of preparatory-rifled work and the excavation unit will be put into operation quickly, which will significantly increase the effect of mining in general. The invention of the method for developing steeply dipping vein deposits in horizontal layers from the bottom upwards with laying out the worked out space and using self-propelled equipment that is fed into the cleaning space along an inclined exit In the process of cleaning, the ramp, an inclined cone, forms in the course of a cleaning voye1mki within the block along its contour at an angle ensuring the movement of self-propelled equipment , Moreover, as the Congress POCH1VY, they use a backfill array erected during the laying of the developed space.
