摘要
Abstract
Taking the 91302 isolated island working face as the research object,an Energy Rock Burst Early Warning Index(ERW Index)is established,and the response relationship of parameters such as S value,b value,energy index and others to rock burst is analyzed.The results show that using the space-time distribution and energy density cloud maps of microseismic events to explain the two rock burst events that occurred on August 22nd and September 28th,multiple rock burst events are comprehensively compared to conclud that the rapid increase in S value,significant decrease in b value,and rapid increase in energy index are important indicators for predicting rock burst occurrence.The established ERW index prediction method significantly improves the accuracy of rock burst prediction.关键词
