综采放顶煤工作面顺槽支护设计分析

Introduction to the Supporting Design of Fully-mechanized Roof Caving Face

针对3号井田煤层工作面顺槽围岩具体的地质情况对原有支护设计进行锚杆、锚索参数优化设计。综采放顶煤工作面顺槽试验巷段共布设2个测站,测站间隔120 m,2个测站同时进行观测。现场应用表明,经过支护设计优化的综采放顶煤工作面顺槽围岩变形得到有效控制,满足矿井巷道稳定要求。

In view of the concrete geological conditions of the surrounding rock of the working face, the original support design was optimized by the anchor bolt and the anchor cable parameters. 2 stations were set up in the tunnel section of the crest face of the fully mechanized coal caving face, the interval of the station was 120 m and the 2 stations were observed at the same time. The deformation of the surrounding rock is effectively controlled to meet the stability requirements of the mine roadway.
