摘要
Abstract
Many faults were exposed in 4401 working face of Yang Quan coal mine, which has the possibility in the presence of rock burst in the fault region. This paper used the force of bolt stress monitoring, stress monitoring and method of drilling bits to monitor the rock burst, provided a guarantee for the prevention of rockburst in this area. according to the research and application of monitoring methods of rockburst in 4401 working face, has certain guiding signiifcance for the next step mining in the complex stress condition.关键词
