木瓜煤矿9-2001巷道支护设计应用实践

Application Practice of 9-2001 Roadway Support Design in Mugua Coal Mine

为了满足木瓜煤矿9-2001巷道长期稳定使用的需要,采用超前物探与钻探技术,探明9-2001巷道掘进地质构造特征,通过支护理论分析及理论计算设计支护方案。设计采用钢筋梯子梁+锚索+钢筋网联合支护方案。该支护方案满足9-2001巷道长期稳定使用需求,可以为9-200工作面回采提供可靠保障。

In order to meet the need of long-term stable use of the 9-2001 roadway of Mugua Coal Mine,advanced geophysical prospecting and drilling technology was used to explore the geological structure characteristics of tunneling 9-2001 roadway,and the support scheme was designed through support theory analysis and theoretical calculation.The design adopted the combined support scheme of reinforced ladder beam+anchor cable+steel mesh.The support scheme can meet the long-term stable use needs of 9-2001 roadway,and provide a reliable guarantee for the remining of the 9-200 working face.
