顶板不稳定状态下矿山开采的设计方案研究

Study on design scheme of mining under unstable roof

针对矿区实际情况,在简述其地质条件的基础上,提出了顶板不稳定这一实际条件下开采方案设计过程中需要严格遵循的几项原则,包括制定有效施工工艺,保证井组连通、优先考虑借助定向水平井进行连通采卤,以此为有类似情况的矿山开采提供参考依据,保证开采效益。

In view of the actual situation of the mining area,based on the brief description of its geological conditions,this paper puts forward several principles that should be strictly followed in the design process of mining scheme under the actual condition of unstable roof,including the formulation of effective construction technology,the guarantee of well group connection,and the priority of connecting brine mining with directional horizontal wells,so as to provide reference for similar mining situations To ensure the mining efficiency.
