摘 要:木城涧矿450水平西四采区三槽东一壁工作面发生的几起冲击矿压事故,与其工作面开采深度、所处地质构造部位、呈孤岛开采状态有关。工作面煤样和顶板冲击倾向性测试结果表明,该煤层属于高冲击倾向性煤层,具有发生冲击矿压的能力。根据产生冲击矿压的原因和特点,采用电磁幅射进行冲击矿压预测预报、爆破卸压进行治理的措施,通过了冲击矿压危险区。Some pressu re bump accidents were happened in 450m level East 1 wall working face, No.3 spout, West No.4 winning district, Muchengjian coalmine, they were tied up with working face depth, structural position and isolated mining. The testing results of working face coal samples and roof impact tendency indicated that the coal seam belongs to high impact tendency and has pressure bumping possibility. According to the pressure bump producing causation and peculiarity, we used electromagnetic radiation prediction, and controlling measures of relieving shot, the hazardous area finally has gotten through.
