基于原岩应力测量的软岩巷道支护优化设计研究

A Study on Soft Rock Roadway Supporting Design Optimal Method based on Ground Stress Measurement

为了解决曹庄煤矿高应力软岩巷道支护困难的问题,进行了井下原岩应力实测,采用基于实测地应力的锚杆支护优化设计方法,优化了巷道支护设计参数。工程实践表明,该支护技术有效控制了高应力软岩巷道围岩变形,取得了良好的技术经济效益,提供了一种控制高应力软岩巷道围岩变形的有效方法,对类似条件下巷道支护设计具有一定借鉴意义。

In order to solve the problem of bolt supporting about high stressed soft rock roadway in the Coal Mine,the optimal bolt supporting design method based on ground stress is put forward,and the optimized design scheme is used to roadway supporting The engineering practices show that the plan could control the strong deformation of roadway surrounding rock,the supporting effect is better than the original support style,and the support cost and maintenance expense sharply decrease.And the method is feasible to controlling high stressed roadway rock.It is referential significance for controlling and maintaining the soft roadway in the similar conditions.
