(54) METHOD FOR DEVELOPING HORIZONTAL MINE LIVING DEPOSITS USEFUL

EXHAUSTED

one

The invention relates to the mining industry and is intended for use in the development of ore and non-metallic mineral deposits by the underground method using self-propelled equipment.

The known method chamber-pillar development, including the separation of deposits with a capacity of 3-8 m on the camera, the driving of the haulage drift and ore passes through the rock, the trench and the notch of the camera on the ore. The chambers work out with a continuous flawless slaughter, giving it a planar shape in plan, with the arrangement.m of horizontal blast-holes parallel to the roof 1.

The closest to the proposed method is the development of horizontal and gently dipping mineral deposits, which includes working the panel with cameras, leaving supporting barrier and columnar pillars, penetrating panel split and ventilation, and drilling the ore into the chambers with layers of solid walls 2.

The disadvantage of this method is the relatively low efficiency of mining of the ore body due to the low speed of the clearing.

The purpose of the invention is to increase the efficiency of mining of the ore body due to the intensification of the clearing recess.

This goal is achieved by the fact that in each chamber, a drilling and ventilation drift passes along its axis, and its transducer is connected, 1.

 tail-ventilation knocks, and of the indicated drifts, drill holes are drilled parallel to the bare plane parallel to the bare plane, and the drilling of the said cords and loading of the broken ore are combined.

From the main haulage shchrek 1 along the barrier pillars 2 pass transport races 8, which behind the first row of interchamber pillars 4 are connected by a split drift 5, from which the ventilation drift 6 passes from the assembly to the assembled ventilation drift 7. Each The camera is driven along the axis of the drill-vent drifts 8. Connecting them with transport-vent connections 9, moreover, from the drill-ventilation drifts 8, with the possibility of non-cutting chamber stocks without solid holes, the holes 10 are located parallel to the exposed plane behind bo; with a deposit capacity equal to the drift height — horizontally; with a deposit thickness greater than the drift height — horizontally plus descending. Drilling the holes and loading the ore in each chamber is combined in time. When the chamber is dredged as the line moves, the temporary tape pillars 11 are left in the bottomhole zone, which are shaped to the size of round 4 as they are dug out of the distance of the hole. equal between axes pillars. Carrying out the drilling and ventilation drifts allows improving the panel ventilation, leading the advance drilling of the faces, combining the processes of drilling and loading, increasing the utilization rate of the self-propelled equipment (due to reducing the movement of drilling and loading machines) and intensifying the working of the panel. In general, these conditions provide the creation of a flow technology for excavating ore, i.e., in each chamber (with the exception of time for blasting and subsequent airing during the interchangeable time), continuous drilling and loading processes occur. Due to the greater stability of the roof (the outcrop area is smaller) and the increased dimensions of the pillars (collapses and delamination of rocks are reduced to the effects of blasting and, consequently, the danger from them to workers in the bottomhole zone. Safety of cleaning works is also increased due to the fact that the number of people who were under the exposed roof, since the drilling and blasting operations are carried out from the workings of a limited section. Formula of the invention The method of developing horizontal and gently dipping deposits Mineral resources, which include working the panel with chambers, leaving supporting barrier and columnar pillars, driving panel split and ventilation mines and shcheonuyu ore blasting in chambers with continuous holes, characterized in that, in order to increase the efficiency of mining the ore body due to the intensification of recesses in each chamber along its axis passes the brown-ventilation drift, connect it with transport and ventilation sboys, and of the indicated drifts, drill holes in parallel to the naked oskosti slaughtering, wherein the drilling of said drilling and loading otbigoy Rud combine.
