Non-coal-pillar-reserved unmanned coal mining method and complete equipment of gently-inclined thin coal seam

Abstract

The invention discloses a non-coal-pillar-reserved unmanned coal mining method and complete equipment of a gently-inclined thin coal seam. The non-coal-pillar-reserved unmanned coal mining method includes the following steps that (1) a coal mining machine is used to collect single drilling hole; (2) a self-moving air stack bracket is moved to the drilling hole position and a top plate is supported; and (3) the step 1 and step 2 are cycled until a whole working face is mined. According to the non-coal-pillar-reserved unmanned coal mining method and the complete equipment of the gently-inclinedthin coal seam. the top plate is supported by the self-moving air stack bracket, the self-moving air stack bracket continuously moves forward along with mining of the coal mining machine, the problemof top plate supporting of the thin coal seam is solved, unmanned mining of a thin coal seam working face 110 construction method is realized, and a foundation for safe, efficient and sustainable development of coal mining enterprises is laid.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to an unmanned coal mining method and a complete set of equipment for gently inclined thin coal seams without leaving coal pillars. Background technique [0002] my country's thin coal seam resources are widely distributed and rich in reserves. At present, the proven recoverable reserves of thin coal seams in the country account for about 19% of the total recoverable reserves of coal. However, due to the influence of "high labor intensity, low degree of mechanization, low safety factor, and low work efficiency", the annual coal mining from thin coal seams only accounts for 10.4% of the country's total reserves, and there are still more to come. Downward trend. The serious imbalance between production and reserves has resulted in the waste of national resources and the shortened service life of mines, which has become a bottleneck restricting the healthy and sustainable develop...
