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 deformation characteristics of soft rock roadway support, this paper proposes the principle of distinguishing the support types of soft rock roadway from three types. From economic point of view, the rationality of the open roadway in hard rock far away from coal seam is given. Out of the mathematical judgment formula, and finally to improve the mining roadway maintenance issues raised the view.
