神东矿区煤炭开采对含水层破坏模式研究
|
摘要
为了能够更快速、更有效地制定和实施煤炭开采区的含水层保护方案,在充分了解神东矿区区域含水层结构特点及与煤层的空间分布关系的基础上,总结提出了6种煤层与含水层空间关系组合模式,并对含水层破坏的模式进行归纳。结果表明:采煤引起的含水层破坏主要为顶板含水层剥离和导水裂隙带发育至含水层2种类型,可以归纳为破坏顶板中-强富水性孔隙含水层模式、破坏顶板中-强富水性砂岩孔隙裂隙含水层模式、破坏顶板风化裂隙含水层模式、破坏顶板向斜型蓄水构造模式、破坏烧变岩含水层模式等5种模式。通过空间关系组合模式可以对应破坏模式,从而可以更快速地判断水文地质条件,掌握含水层破坏特征,有利于矿区水资源保护和煤矿安全生产。
In order to formulate and implement the aquifer protection scheme for coal mining areas more rapidly and more efficiently,based on the adequate appreciation of the spatial relationship between the coal seams and the aquifers in Shendong Mining Area,this paper introduces six coal seam-aquifer spatial relationship models,and summarizes different aquifer failure modes.The result shows that,the aquifer failure caused by coal mining falls into two types,namely the roof aquifer delamination and the water flowing fractured zone developing to the aquifer.Accordingly,five types of aquifer failure modes are proposed,specifically,mid-strong water yield property porous aquifer roof failure mode,mid-strong water yield property porous-fractured aquifer roof failure mode,weathered fractured aquifer roof failure mode,syncline type water storage structure roof failure mode,and burned rock aquifer failure mode. The coal seam-aquifer spatial relationship corresponds to the failure mode,and thus hydro-geological conditions in mining area can be determined more quickly,which is helpful for the protection on water resource and safety production in mining area.
