摘    要:2#辅助运输石门底鼓严重影响矿井建设与生产运输。通过现场调研、理论分析与室内试验,发现巷道埋深大,水平构造应力高,致使无支护的底板围岩产生挤压变形。设计了反底拱+底角锚杆耦合技术的治理方案。

关 键 词:深埋巷道  软岩  高地应力  底鼓  控制技术

Abstract:The floor heave of No.2 subsidirary transportation roadway seriously affected building of mines and transporting of production.Based on the on-site survey,theoretical analysis and laboratory test,find roadway bury deeply,high horizontal tectonic stress,producing extrusion deformation of nonsupport country rock in floor.Designing inverted arch and base angle bolt treatment scheme.
Keywords:deep roadway  soft-rock  high ground stress  floor heave  control technology
