保护层开采上覆矿床变形移动及矿层气地面抽采效果

Deformation, movement and gas extraction effect of overlying deposits in protective layer mining

我国矿产资源储量丰富,各个地区存储了不同类型的矿层构造,对实地开采与生产造成了诸多难度。保护层开采上覆矿床变形移动规律,可指导现场采矿生产流程的一体化。同时,掌握矿层气地面抽采技术要点及应用效果,对矿层开采与分析起到关键作用。据此,本文分析了保护层开采上覆矿床变形移动规律及矿层气地面抽采操作方法。

China is rich in mineral resources, and different types of ore deposits are stored in different areas, which have caused many difficulties in field mining and production. The deformation and movement regularity of overlying deposits can be guided by the protective layer, which can guide the integration of the mining production process at the site. At the same time, mastering the main points and application effects of gas extraction technology plays a key role in mining and analysis of the seam. Therefore, this paper analyzes the deformation and movement rules of overlying deposits and the method of gas extraction operation.
