松软煤层巷道支护技术研究
|
摘要
针对煤矿松软煤层巷道围岩承载构造中顶板及两帮相对薄弱问题,以赵庄煤业为研究背景,对其支护技术进行了研究设计,详细地分析了支护方式以及参数。结果表明,该支护方式能够有效控制顶板及帮部变形,增强巷道围岩稳定性,为今后进一步研究奠定了基础。
Aiming at the relative weakness of roof and two sides in the bearing structure of roadway in soft coal seam,taking Zhaozhuang Coal Industry as the research background, the supporting technology is studied and designed, and the supporting mode and parameters are analyzed in detail. The results show that the support method can effectively control the deformation of roof and side, enhance the stability of surrounding rock of roadway, and lay a foundation for further research.
