龙门山矿区套孔应力解除法测定原岩应力
The rock stress measurement by trepanning stress relief method in Longmenshan mining region
摘要
Abstract
Measuring rock stress is important for optimizing mining sequence and roadway design of Longmenshan Mining region. Trepanning stress relief method is applied to measure the rock stress of Longmenshan mining region. Stress size, orientation, and their distribution law are obtained. The results show that rock stress increases with the depth. The horizontal stress is the maximum stress. The direction of the principal stress conforms to roadway alignment. The roadway design is reasonable.关键词
