地下采掘作业中矿山岩石力学理论的应用

根据矿床开采引起的围岩变形情况，通过对岩石的变形特性的分析，以及对原岩应力和次生应力论述，我们对地下采掘作业中巷道和采空区围岩的力学特性做了相关研究并取得了一些研究成果。这些研究成果可为地下采掘作业提供理论指导，对确定采场结构参数和布置方向，选择采场回采顺序，制订采场支护措施等都具有十分重大的意义。

Application of mine rock mechanics theory in underground mining

According to surrounding rock deformation brought about by mining, mechanical properties of roadway and goal surrounding rock are correlatively studied , and a few research results are achieved through the analysis of deformation properties and the exposition about the original rock stress and secondary stress. These research results can provide theoretic instruction for the underground mining operation,it has great significance to determine the parameters of stope structure and layout ,selection of stoping sequence, stope support measures.
