摘要:

为了掌握深部卸压厚煤层开采矿压显现特征,结合丁集煤矿13-1煤1282(3)和1141(3)工作面地质和开采技术条件,通过现场实测综采面卸压开采矿压显现特征,对比分析表明,卸压开采使得被保护层回采期间矿压显现强度有所降低,支架适应性良好,煤壁片帮情况改善,有利于采场围岩控制,为类似地质条件下工作面开采提供一定的参考依据。

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
