摘要
采用了与工作面回采方向相反顺序的微差松动爆破措施，对该矿的采区冲击地压进行了爆破解危试验，结果表明措施是成功的，可在全矿及相同条件的矿井中借鉴。
In-situ experiment of microsecond blasting concussion whose detonating sequence follows the inverse direction of stoping has been carried out to prevent rockbust in stope of the coal mine,the experimental result appears to be successful and the measure can be taken and spread both in Tianchi Coal Mine and other collieries with the same situations.\=
