摘要
介绍了水压致裂地应力测量原理及在现场中的具体应用,通过现场地应力测量为巷道支护初始设计提供了重要的基础参数,实践证明地应力测量结果对提高巷道支护设计的科学性与可靠性有着重要意义。
The paper introduced the principle of the strata stress measurement with hydraulic cracking and the certain application at the site. With the site strata stress measurement, important basic parameters can be provided for the initial design of the mine roadway support. The practices showed that the results of the stress measurements had important significances to improve the science and reliability of the mine roadway support design.
