孤岛工作面迎采巷道掘进支护技术研究

Research on tunneling support technology ofisland working face mining roadway

针对寺家庄矿5110孤岛工作面巷道掘进支护技术难题进行研究,通过采用理论分析、支护设计优化等方法,对孤岛工作面迎采巷道掘进支护技术进行了研究分析,在5110工作面进行了现场实践。实践表明,优化后的支护方案应用效果良好,巷道围岩变形与支护压力大等现象得到明显改善,为类似条件下的孤岛工作面迎采巷道掘进支护提供经验借鉴。

In view of the technical problems of roadway excavation and support in 5110 island working face of Sijiazhuang Mine,the theoretical analysis and support design optimization were used to study and analyze the roadway excavation and support technology of island working face.The practice shows that the optimized support scheme has a good application effect,and the deformation of roadway surrounding rock and the large support pressure have been significantly improved,which provides experience for the tunneling support of the mining roadway in the island working face under similar conditions.
