摘要
为解决石沟驿煤业公司软岩半煤岩巷严重失修状况,以巷道变形监测、矿压监测和在役锚杆力监测为手段,分析巷道变形原因,确定合理支护参数。通过实践,证明了该锚网索联合支护效果较好,满足安全生产需要。
In order to solve the situation of serious disrepair of the soft rock and half coal and rock roadway of Shi Gou Yi Coal Co.,Ltd,analyze the causes of distortion of roadway by taking the monitoring of the deformation of the roadway,the monitoring of mine pressure and anchor rod force as the means and confirm the reasonable support parameter. It is proved through practice that the effect of the combined support of bolt,mesh and anchor is good which can meet the needs of the safety in production.
