摘　　要：为了合理评价钻孔卸压技术对冲击地压事故的防治效果,采用理论与现场实践相结合的方法,对钻孔卸压机理进行分析,提出采用钻孔后的塌孔程度、时间及塌孔距工作面的距离作为评价防治冲击地压效果的三因素,并在煤矿工作面分别采用钻屑法与本文所提方法进行对比评价。结果表明,文中所提方法与钻屑法分析结果一致,证明了新的评价方法的正确性和可行性。To reasonably evaluate the prevention effect of drilling pressure relief technology on rockburst accidents,the drilling pressure relief mechanism was analyzed using a combination of theory and field practice.To evaluate rockburst prevention,we proposed three factors:borehole collapse degree,time,and the distance between the borehole collapse and the working face.The drilling cuttings method and the method proposed in this paper were used to evaluate in the working face.The results showed that the method proposed in this paper was consistent with the drilling cuttings method,which proved the correctness and feasibility of the new evaluation method.
