中文摘要：

从地质环境、地球化学、分布式水循环模拟、水文地质数值模拟等多角度,研究了采煤沉陷积水与浅层地下水之间的转换关系。研究结果表明：采煤沉陷形成的地表裂隙,垂向上发育深度有限,透水性不强;采煤沉陷区的积水主要来自大气降水补给,而非地下水;沉陷区积水与地下水间的作用过程具有明显的阶段性,在汛期基本上表现沉陷积水补给浅层地下水,在非汛期表现为浅层地下水净补给,但补给量较小。

英文摘要：

For quantitative cognition of water resources transformation rules between coal mining subsidence water and shallow groundwater, the transformation relationship between coal mining subsidence water and shallow groundwater is studied from the point of geological environment, geochemistry, distributed water cycle simulation, numerical simulation of hydrological geology, etc. The results show that：the surface fissures formed by coal mining subsidence are limited in vertical direction, and the permeability is not strong; The water in the coal mining subsidence area mainly comes from the meteoric water, not the ground water; The process of action between subsidence area water and groundwater has obvious stage, subsidence water recharge shallow groundwater in flood season, net recharge of shallow groundwater in non-flood season, but smaller supply.
