Abstract

The invention belongs to the technical field of mining and safety engineering and discloses a rock burst control method in a deep mining area of a coal mine. The method comprises the following steps: a, arranging a first coal mining face on an upper coal seam in a mining area uphill direction; b, arranging a mining area uphill preparation roadway group in a stress decreasing area below the gob; c, arranging an upper coal seam working face and a lower coal seam working face on two sides of the main system for performing stoping after the uphill preparation roadway group is formed; d, performing local pre-unloading treatment or rock burst danger releasing measures on a haulage way, a tail gate, an open-off cut and the like of the upper coal seam working face. The invention provides a method for effectively improving the rock burst control effect in the deep mining area of the coal mine.

Description

technical field [0001] The invention relates to the technical field of mining and safety engineering, in particular to a method for preventing and controlling rock burst in deep mining areas of coal mines. Background technique [0002] At present, the mining intensity and depth of mines are gradually increasing. A large number of mines have entered the deep mining stage one after another. The depth increases by 10-20m per year. They have entered or will soon enter the mining below 1,000 meters, and some new mines even have the first working face reaching 1,000 meters. [0003] The deep mining of the mine is faced with the harsh environment of "three highs and one disturbance", coupled with unreasonable development and mining layout, geological structure, etc., the disasters that did not appear in the shallow mining or were not obvious are gradually revealed or become more intense. Among them, rock burst, as a typical coal-rock dynamic disaster, is complex and destructive, wh...
