Embodiment Construction

[0063] The present invention will be further described below in conjunction with the description of the drawings and the specific embodiments.

[0064] Preliminary preparation conditions for rapid moving of sequential mining face

[0065] (1) The pre-dug and withdrawal channel combined with the construction technology of the final mining of the reorganized net

[0066] 1. Cooperate with the final mining process of the reorganized net on the working face to be withdrawn

[0067] The coal company takes the working face to be withdrawn as a research pilot, and adopts the mining high-strength polyester fiber flexible net (hereinafter referred to as "flexible net") roofing process for the face finishing work, replacing the traditional metal diamond net roofing process. The mesh is large in area, flexible and light, with high tensile strength, simple process, easy to operate, good flame retardant and antistatic performance, avoids frequent network operation and networking procedures, high s...

Abstract

The invention relates to a process for rapidly moving the equipment of large-mining-height ordered mining working surfaces. According to the present invention, the working surface to be retracted andthe working surface to be mined are the adjacent ordered mining working surfaces; the working surface to be retracted performs the terminal mining by combining the pre-excavation retracting channel and the net finishing so as to create the conditions for the retracting of the large-volume and large-tonnage comprehensive equipment; and during the installation of the working surface to be mined, thehydraulic bracket and the scraper conveyor are installed after the open-off cut working surface side coal wall is widened to 4 m.

Description

Technical field [0001] The invention relates to the movement and relocation of complete sets of fully mechanized mining equipment such as hydraulic supports, shearers, scraper conveyors, reloaders, etc., for fully mechanized mining faces with large mining heights in underground coal mines, and specifically relates to a rapid moving process for sequential mining of large mining heights. Background technique [0002] According to relevant statistics, my country’s currently proven coal geological reserves are about 1,000 billion tons, and thick coal seams account for about 45%. At the same time, thick coal seams account for about 40% to 50% of total production. Reasonable mining of thick coal seams The production and economic development of my country's coal industry have a pivotal impact. It is worth noting that there are thick coal seams below 6.0m in many mining areas in my country, such as Jincheng, Lu'an, Datong, Yangquan, Xingtai, Xuzhou, Chongzhou, Fuxin, Tongchuan and Shenfu ...
