岩爆的应力解释与新预警方法
A New Prediction Way and Interpretation about the Rock Burst Stress
【摘要】 以大量的实际工程资料为依据,通过系统的理论分析,提出了洞窟周边各向应力均达到或超过洞窟周边岩体极限压碎强度时就会发生岩爆的见解,给出了新的岩爆预测方法和洞窟周边各向应力计算方法。
【Abstract】 According to many practical engineering data, a new rock burst theory is advanced, that is, the rock bu-rst occurs once each stress around the mineral cave comes up to go beyond the limit crush strength of the rock stratum around the mineral cave. It gives a new prediction way about the rock burst and a new calculation method of each stress around the mineral cave.
