Abstract

This invention relates to the underground mining of complex coal deposits. The purpose of the invention is to increase the efficiency of a geological disturbance transition by reducing the clogging of coal by rock. The preparatory development passes along the geological disturbance along the coal to the slip plane with the exposure of its surface. When placing the coal seam above the lava mark, the excavation takes place before the violation, and when placing the coal seam below the lava mark, the production passes after the violation. The guides are laid in the development in the direction of movement of the complex at an angle not exceeding the allowable angle of inclination of the complex. One end of the rails is placed on the soil of the formation, the other - on the sliding surface of the violation. Roofing rocks and seam soil are prevented from moving. Part of the rocks from the demolition are placed below the rails, and the remaining excess rocks are moved into the open space. 2 h. item f-ly, 6 ill. "(L

Description

The invention relates to the mining industry and can be used in the preparation of zones of geological disturbances to the transition by lavas with cleaning mechanized complexes under permafrost conditions or strong enclosing rocks.

The purpose of the invention is to increase the efficiency of the transfer of geological disturbances by reducing the clogging of coal by rock.

FIG. 1 shows a diagram of the preparation of a geological disturbance zone for a transition by a cleaning mechanized complex, a plan view; in fig. 2 — part of the development carried out along the geological disturbance in the plan; in fig. 3 - cut

A-A in FIG. one; in fig. 4 - generation after the undermining of roof rocks and soil, cross-section; in fig. 5 and 6 - the same, at the moment of transition of the geological disturbance by the mechanized complex, the cross section.

The method is carried out as follows.

Before approaching the mine 1 to the geological disturbance 2, along the geological disturbance, generation 3 along the coal is applied to the slip plane of the violation. In this case, the slip plane of the violation (mixer) 2 is exposed. Then, in the development 3, guides 4 are laid in the direction of movement of the complex as follows.

about

that one end of the guides is stirred on the soil, and the other on the slip plane of the disturbance (mixer) 2 The angle of inclination of the guides 4 is chosen so that it does not exceed the allowable angle of inclination of the mechanized complex 5

Wood, pipes, beams, etc. are used as guides.

Claims (1)

Claim 1 Method of preparing a geological disturbance zone for transition by lava with a mechanized complex, including preparatory development along 5 geological disturbance, laying in the development of guides in the direction of movement of the complex, one end of which is placed on the soil of the coal seam, excavating the roof rock and coal seam soil pre (d) beams, etc., of the transition, and placement of the roof and soil rocks, 6, and one from the demolition of the BELOW direction of the transition, are carried out with the purpose of drilling and blasting operations. The loosened rock is placed in the mine: a part of the rock takes up space below the direction 15 - - -1g Luzhshikh 4, and part - above them in the developed space To increase the efficiency of the transition by reducing the clogging of the coal by the rock, the preparatory development takes place along the coal inlet to the glide plane of the disturbance with the exposure of its surface, the guides are laid at an angle In the process of transition of the geological not exceeding the allowable angle of inclination 2 of the mechanized complex 5 onto the complex, the second end is gradually pulled over the guides of the 4 2o guides placed on the surface and moved along them. stir under the guides 4, and surplus scraps are moved into the worked-out rock formations pass through the conveyor belt Comgmex 5 into the goaf 2 The method according to claim 1, wherein that when a coal seam is placed beyond the geoEes if coal seam 7 behind the mixer has an elevation violation above the lava of the sheni elevated, then coal production 3 preparatory production takes place before carried out before the violation of eologicheskoy violation (FIGS. 2-5) If coal seam 7 is omitted, 3 The method according to claim 1, characterized in then production 3 is placed beyond the geologic-that when the coal is placed behind the geological disturbance (Fig. 6). As the transition proceeds, the guides 4 can be removed for reuse. By a violation of below the lava mark, preparatory generation is carried out after the violation. Claim 1: A method of preparing a geological disturbance zone for a lava transition with a mechanized complex, including preparatory development along the geological disturbance, laying in the development of guides in the direction of movement of the complex, one end of which is placed on the soil of the coal seam, excavation of roof rocks and coal seam soil, pre the transition and the placement of the coal at the location of the coal seam after the geological disturbance below the lava mark, the preparatory development takes place after the violation. figure 1 / Schi 2 Aa Fig.Z Figm FIG. five FIG. 6
