针对砂墩子煤矿猴车巷巷道两帮受压变形明显、巷道支护工程量大等问题，为达到最大限度地保障安全生产、提高掘进速度和控制围岩稳定的目的，决定优化既有巷道支护方案。通过巷道破坏变形分析、围岩地质力学测试和动态信息支护设计法，提出了三种支护方案，采用“锚网索梁喷”支护，优化了支护方案，在后期的工程实践中，取得了良好的效果。%In view of the problems that the compressive deformation of the two sides of Houche Lane roadway of Shadunzi Coal Mine is obvious and roadway support requires large constructin quantity, and in order to ensure production safety, improve the tunnelling speed and control the surrounding rock stability, we decided to optimize the existing roadway support scheme. Through roadway destruction deformation analysis, surrounding rock geological mechanics test and dynamic information supporting design method, three support schemes are put forward. Wire mesh cable beam spray support is used to optimize the support scheme and good effect has been achieved is the later construction.
