摘要
在分析软岩巷道支护变形特征的基础上，提出区分三种类型软岩巷道支护型式的选择原则；从经济角度论述了特定情况下巷道开在远离煤层的硬岩中的合理性，给出了数学判断算式，最后对改善回采巷道的维护问题提出了看法。
Based on the analysis of the support deformation characteristics in soft rockroadway,this paper puts fooward the choosing prirciple of support forms according to threekinds of soft rock roadway,it also discusses the reasonability of roadway excavated in thehard rock far away from coal seam in special conditioit, and gives judgement formula,Finallyit points out the attentive problems of improving actual mining roadway maintenance.
