Abstract

Summary of the invention: when the mechanic complex approaches the geological disturbance lock, the mechanized support is disconnected from the bottomhole conveyor 4. The bottomhole conveyor and the piles of the clearing hole 5 are pushed into the distance not less than the working width of the executive body of the mining combine. A hinged connection of the downhole conveyor with mechanized support sections is provided by a spacer 6. Hydrojacks 8 are installed at the transition points of the geological disturbance to the supports of the mechanized supports at the roof of the formation. which burst the mech. As the geological disturbance proceeds, the articulation is transferred to the next section along the length of the clearing hole. 1 hp ff, 3 ill.

Description

Fig.Z

The invention relates to the mining industry.

The purpose of the invention is to increase the load on the working face by broadening the working space of the clearing face and marking the trajectory of the mechanics complex in the transition zone of the geological disturbance.

FIG. 1 is a diagram of a transition of a geological disturbance by a mechanical complex; figure 2 - the node in figure 1; on fig.Z - section aa in figure 2.

The method of transition of geological disturbances by the mechanized complex is carried out as follows.

With the approach of the mechanized complex 1 to the geological disturbance lock 2 for several sections of the mechanical support 2, the bottomhole conveyor 4 is disconnected from the lower base of the mechanical support sections and retracts the bottom 5 to the chest at least the width of the executive body of the mining combine, and then the hinge is connected to downhole conveyor 4 spacer 6, which eliminates the engagement of the executive body of the mining combine with visors lining 7.

In addition, in this zone, as well as above and below the geological disturbance lock, hydrojacks 8 are installed on racks of sections of mechrepm at the roof of the seam, which burst into the chest of the clearing bottom 5, thus preventing the section of mech supports from tipping over the bottom of the chest. As the sections of the support of the castle part move, the articulated spacers 6 between the lower base of the sections of the support and the shifter jack are transferred to the next section along the length of the clearing face. This sequence of operations is repeated until the mechanic complex is completely transferred to the discharged part of formation 9.

In order to orient the sections of the mech support in the castle of geological disturbance into the solid coal from the clearing hole at the design angle, we drill 10. The wells are drilled at various levels along the extracted power at an angle equal to the movement of the sections.
