本文从工程地质条件和岩石力学两方面对地下洞室围岩的变形破坏规律的分析,对特定地质条件下煤矿开拓系统布置层位的选择做出评价,提出合理经济的层位选择方案。
In this paper, the deformation and failure of surrounding rock in underground caverns are analyzed from both engineering geological conditions and rock mechanics. The evaluation of the selection of layers of coal mining system under certain geological conditions is made, and a reasonable and economical horizon selection scheme is proposed.
