根据系统工程思想 ,运用矿压理论、爆破理论和煤层注水原理简要论述了深孔爆破和动压注水相结合预先弱化处理坚硬煤体的作用机理 ,分析了红会一矿 1 50 2 - 1 厚煤层分层综采工作面试验情况及其效果 ,得到了其合理的预处理工艺参数。研究和试验表明 ,深孔爆破和动压注水相结合预先弱化处理坚硬煤层方法安全可靠 。
According to the system engineering thought,using the theory of mining pressure,blasting and infusing water,the mechanism that deep hole blasting and dynamic pressure infusing water can weaken the hard coal body is expounded.The test and its effect at the face 1502 -1 of the No.1 Honghui Mine is analysized,and the rational parameters is obtained.The study and tests show that this method is safe and reliable,it is a kind of new way to promote the productivity and efficiency of fully mechanized mining.
