Fully-mechanized mining working plane supplementary laneway multiple passage quick-speed moving process

Abstract

The invention discloses a fully-mechanized mining working plane supplementary laneway multiple passage quick-speed moving process which comprises, excavating two substantially parallel auxiliary channels spaced apart of a predetermined distance along the coal wall at the working surface mining stop line position, making at least one auxiliary channel to be the withdrawing channel of the working surface holder withdrawal, making at least another auxiliary channel to be the transportation channel of the working surface holder withdrawal, then excavating a plurality of connecting channels between at least two of the auxiliary channels, thus realizing the aim of quick-speed withdrawal.

Description

technical field [0001] The invention belongs to mining technology, in particular to a multi-channel fast moving method for auxiliary lanes in a comprehensive mechanized coal mining face. Background technique [0002] The relocation of the fully mechanized mining face is an important production preparation work of the fully mechanized mining production mine. It is not only an important link to realize safe production in the mine, but also directly restricts the improvement of the unit yield level of the fully mechanized mining face. In my country, the auxiliary transportation mode of most mines is rail transportation. Therefore, the transportation of fully mechanized mining equipment can only be carried by rail transportation. Auxiliary devices such as unloading tripods and iron plates realize the unloading, direction adjustment and installation of fully mechanized mining equipment; the retreat of the working face generally adopts the method of self-made retraction space of th...

AI Technical Summary

Problems solved by technology

[0004] 1) During the final mining period of the fully mechanized mining face, it is not only necessary to lay steel wire ropes and metal mesh, but also to reserve a retraction space for the fully mechanized mining equipment. Under the premise that the hydraulic support does not move, the shearer and the scraper conveyor need to be integrated. Move forward to carry out coal drop-off, loading and transportation, and need to increase the support work of the overhanging roof space. There are many work links, slow progress, and difficult safety management, and it is impossible to achieve rapid advancement of final mining;

[0005] 2) Due to the use of rail transportation for the shipment of fully mechanized mining equipment, it is necessary to set up a loading platform for the equipment. There are many links in the dismantling, loading and transportation of the equipment, which is time-consuming, uses many auxiliary equipment and auxiliary facilities, and has poor safety , unable to achieve fast retracement;

[0006] 3) Due to the backward rail transportation method used in the installation of the traditional fully mechanized mining face, the cutting eye of the working face must be laid with transportation rails, and the rails are recovered while installing. The process is complicated and it is not easy to achieve fast installation
