深竖井井筒围岩岩爆倾向性预测分析
摘要
Abstract
Rock burst tendency analysis is the basis for rock burst prevention and control.Based on a deep shaft in Jiaodong area as an engineering background,the basic parameters for rock burst tendency evaluation are obtained by carrying out rock mechanics tests and ground stress tests,and four indicators including evaluation indicators(impact energy index,elastic strain energy index)and external surrounding rock condition indicators(ground stress index,RQD index)are selected to conduct rock burst tendency analysis and research.Research shows that most of the rockburst tendencies in the shaft depth range from 1 000 m to 1 500 m range from moderate to strong rockburst.The tendency of rock burst in the deep area of the shaft is the result of the joint action of many factors such as the nature of the rock formation itself,rock integrity,and ground stress conditions.During construction,for rock formations with good integrity,drilling pressure relief,flexible support and other technologies can be used to prevent and control rock burst disasters in deep shafts.关键词
