摘要
对某煤矿工作面及其沿空留巷情况进行了介绍,在分析沿空留巷围岩基本属性的基础上,对其巷道支护技术方案进行了全面设计,给出了具体的技术参数。将设计的支护方案应用到工程实践中,对巷道围岩表面变形情况进行监测,取得了较好的应用效果,为煤矿企业创造了较大的经济效益。
This paper gives a brief introduction to the working face of a coal mine and the situation of roadway retention along the gob.Based on the analysis of the basic properties of the surrounding rock of the roadway retention along the gob,a comprehensive design of its roadway support technology scheme is given and specific technologies are given,parameter.The designed support scheme was applied to engineering practice,and the surface deformation of the surrounding rock of the roadway was monitored,and it was found that a good application effect was achieved.The technology of retaining lanes along the goaf has created greater economic benefits for coal mine enterprises.
