Introduction
Underground coal mining can affect wells and springs used as domestic water supplies; subsidence caused by underground mining is generally acknowledged to be a primary cause of groundwater resource effects. In coal- producing regions of Virginia and neighboring states, many rural residents depend on groundwater as their pri- mary water source. The purpose of this article is to report the results of an analysis of water supply impacts of underground mining in Virginia. Reports of 73 water supply investigations mation (VDMLR) were analyzed in conducting this study (Zipper and others 1994). The VDMLR investigations were conducted between 1981 and 1987 for the purpose of resolving disputes between surface residents and un- derground mining firms. The effects of underground mining on water supplies has been addressed by federal legislation. Section 2504 of the Energy Policy Act of 1992 requires mining firms to re- place water supplies damaged by underground mi

导言
地下采煤影响水井和泉水用来作为国内的食水供应;沉陷地下开采引起普遍承认，成为一个主要的原因地下水资源的效果。在煤炭生产地区的弗吉尼亚州和周边国家，许多农村居民依赖于地下水作为其PRI的-玛丽水源。本文的目的是要报告的结果，分析了供水的影响，地下开采在维吉尼亚州。报告73供水调查mation （ vdmlr ）分析了在开展这项研究（拉链等1994年）。该vdmlr调查期间进行的1981年和1987年为目的的解决纠纷的表面之间的居民和联合国derground矿业企业。影响地下开采的供水已得到解决，由联邦立法。第2504年的能源政策法案规定， 1992年矿业企业重新供水的地方，损坏地下开采。维吉尼亚州制定的法例， 1993年作为一项修正案， vcsmcra （第45.1-258 ，守则，弗吉尼亚州）也重新quires水更换。实施这些法律，法规latory机构制订准则，以便确定wheth儿或不指称供水的影响，事实上，民英有关。
