Abstract

Abstract:

In order to grasp the pressure behavior of destressed mining in deep thick seam, based on the geologic and production and technological conditions of working faces No. 1282(3)and No. 1141(3) in DingJi Coal Mine, by ground pressure observation and comparison, the paper have studied strata behaviors in destressed mining, it show that: the underground pressure intensities of the released mining seam could be decreased, the adaptability of supports is good, the wall stability has improved and it is helpful to strata control around longwall face. It has reference value to the future similar coal mine mining safety.

Key words: deep mining, destressed mining, large mining height, pressure emerge
