Embodiment Construction

[0020] A method for safely moving and withdrawing heavy equipment for fully mechanized caving in extra-thick coal seams with a complex structure described in the present invention includes support for stopping mining, roof support during removal, and a removal route.

[0021] At present, the roadway layout and ventilation system of the fully mechanized coal caving face with complex structure and extra-thick coal seam are as follows:

[0022] Roadway layout of working face

[0023] The working face is arranged with two lanes, one entry and one return, and the two troughs are perpendicular to the main alley (including belt lane 4, auxiliary transportation lane 5 and return air lane 3), of which belt lane 1 and auxiliary transportation lane 2 are along the coal seam Bottom layout: belt channel 1 is connected to belt lane 4 of the main road, auxiliary transportation channel 2 is connected to the auxiliary transportation lane 5 of the main road through the connecting lane, and the ...

Abstract

The invention discloses a safe moving and withdrawing method of complex-structured thick coal seam fully mechanized heavy equipment. A moving and withdrawing route comprises a moving and withdrawing transport route through an assisted transport gate road, i.e. from a working face to the assisted transport gate road to an assisted transport gate road roundabout channel to an assisted transport tunnel to an auxiliary adit to a stock yard, and a moving and withdrawing transport route through a belt gate road, i.e. from the working face to the belt gate rod to a return airway to the assisted transport tunnel to the stock yard; and a reasonable mining-stopping supporting method and a roof supporting method during the period of moving and withdrawing are simultaneously combined. By virtue of the moving and withdrawing method, maximum effectiveness of labor force and equipment resources are fully developed, long-distance comprehensive transportation of the thick coal seam fully mechanized heavy equipment is realized, and safe and fast moving and withdrawing of facilities in the working surface is ensured.

Description

technical field [0001] The invention relates to a coal mine production method, in particular to a method for safely removing heavy equipment underground. Background technique [0002] The relocation of the working face is a huge systematic project, an important part of creating a high-yield and efficient mine, and a crucial link in the preparation of mine production. Whether the rapid relocation of "safety, high-quality, and high-efficiency" can be realized is an important guarantee for high-efficiency mine production, and it is also a major technical problem that has plagued coal companies for many years. The whole process of relocation of the working face has many points, wide areas and long fronts. Only by taking into account all construction and preparation links and making careful and reasonable arrangements can the goal of rapid relocation of the working face be achieved. [0003] At present, most fully-mechanized mining working faces of most mines generally adopt the...
