摘要
8103工作面由于周期来压强度大,工作面推进困难,通过在两巷端头及工作面进行深孔爆破,对下位基本顶实施爆破强制弱化措施,以减小工作面中部结构块体的长度,从而降低工作面来压步距及来压强度,保证工作面顺利推进。
Due to the high cyclic pressure intensity,the 8103 working face is difficult to advance.Through deep hole blasting at the ends of the two alleys and the working face,forced weakening measures are implemented for the lower basic roof to reduce the length of the structural block in the middle of the working face,thereby reducing the pressure step and strength of the working face,and ensuring the smooth progress of the working face.
