摘要
本文研究了长壁采煤法回采巷道岩层控制的关键地段,并通过岩层运动的机理的探讨,分析了巷道上方岩体扁壳结构特征,扁壳结构内力分布等问题;同时提出在回采巷道支护理论方面值得研究的几个问题,进而提出回采巷道岩层控制的若干手段。
By analysing the ground pressure acting on roadways based on the practice of roadwaysupporting, the writer of this paper put forwarda concept that a shell construction may beformed in the superjacent strata above the junc-tion of gate road and longwall face. This shellconstruction is a time-dependent four dimen-sional construction whose character is related tothe concrete condition of the gate road. In con-nection with such shell construction, the meansof strata control should mainly be the 'activesupport' and 'integrated support'. The mostcritical range for maintenance is the section ofseveral tens meters before and behind the face-line.
