深井动压岩巷锚喷网加固研究

Bolting wire mesh shotcrete reinforcement of deeprock headings affected by mining

深井动压岩巷加固或返修一般根据经验选取金属支架，造成巷迟成本增加、断面变小等。本文根据实测松动圈分析、研究采动次数、岩性对松动圈的影响，并依据松动圈理论设计锚喷网支护参数，进行工业性试验并获得成功，取得了显著的社会、经济效益，对于指导受采动影响巷道加固或返修具有普遍的实践意义。

Reinforcernent or reconstruction of deep rockheadi ngs affected by mining generally adopts metalsupports by experientially choice,which results inincreasing the cost of driving and the convergence of thecross section of the headings.By analysing the measureddata of″loosened rock ring″surrounding the headings,thepaper studied the influence of mining times,rockproperties on the loosened ring and designed the parametersfor bolting wire mesh shotcrete supporting.Its industrialtests were successful with remarkable social and economicalprofit,and has generalized practical significance to thereinforcement and reconstruction of roadways affected bymining.
