摘要: 深部软岩巷道岩性不均匀,各岩层岩性差别较大,岩石遇水风化软化现象严重。矿压监测能够确定工程岩体力学属性,对增加矿井产量,提高矿井的经济效益具有重要的意义。收敛变形测试是对支护效果的检验与评价,为确定最经济有效的支护方案提供了依据。内蒙古上海庙矿业有限责任公司榆树井矿巷道施工出现了变形、开裂、底臌现象,顶板及两帮位移变形较大,为了保证巷道的稳定和生产的安全,进行了矿压监测和收敛变形测试,为矿区软岩巷道工程的综合治理提供必要的基础。

Abstract: The lithology of the deep soft rock roadway isn't uniform and the lithology of different stratum differs greatly.The rocks are weathered and softened seriously when encountering water.Rock pressure monitoring could determine the rock mechanical properties,having a great significance on improving the mining yield and the economic benefit.Convergence deformation testing is the inspection and evaluation of the supporting effect,providing the basis of determining the most important economic and effective support scheme.Yushujing mine,affiliated to Shanghaimiao Mining Co.,Ltd,appears destruction deformation,cracking,floor swelling and the large deformation displacement of the two-sides.In order to guarantee the stability of the rock roadway and the safety of the production,rock pressure monitoring and convergence deformation testing are carried out,providing the necessary foundation of comprehensive treatment of the roadway.

Key words: Rock pressure monitoring, Convergence deformation, Deep mine, Soft rock roadway
