强冲击危险厚煤层孤岛工作面切眼贯通防冲动态调控
Dynamical control of scour prevention in the isolated thick-seam working face with high outburst risk during its cut transfixion
摘要
Abstract
With the typical mining face with high outburst risk as background,the cut stress in the iso-lated working face with high outburst risk was analyzed,and based on field measurement of such criti-cal indexes of outburst risk as drilling bits and electromagnetic radiation,the multi-parameter outburst monitoring and assessment system was built for the dynamic control of stress and outburst prevention during the cut transfixion.The results have shown that it is predicting and pertinent to regulate and con-trol rock burst stress based on the tendency of microseismic energy release and its position accumulation;the technologies of stress control and outburst prevention based on multi-parameter monitoring of out-burst and the real-time field feedback of outburst prevention effect,help realize smooth cut transfixion in the isolated working face with high outburst risk.关键词
