摘　　要：针对"能源金三角"现代煤炭开采对地下水、生态环境的影响和存在的问题,以神东矿区超大工作面综采为例,研究了现代开采技术下高精度的四维地震、地质雷达、电法等探测方法,研究地下水资源空间分布及变化规律的效果,首次建立了高精度四维多属性数据体,提出采动覆岩具有渗漏-渗流-微渗流的多层结构模式和自修复能力分层递增特征,对开发与现代开采技术相适应。的地下水资源保护和生态环境减损技术,具有重要指导意义。Taking Shendong modem super-large face as a case, the paper focus on the high-precision detecting system for study of impacts on the groundwater and eco-environment in ＂Energy Golden Triangle＂ of west China. The system, composed by the 4-D Seismic Method, Geo-Radar, Electrical Method, is designed along the face and surveyed during all stage, including pre-mining, during-mining, post-mining and stable period. It is first that the spatial distribution of groundwater resources and the validity of the system were discussed, based on created 4-D multi-attribute data body available to describing the variation process in detail. The groundwater flow pattern, constituted by the leakage - seepage - micro-seepage with the vertical multi-layered structure, is established and self-repair capacity with layered increasing characteristics is proposed. The result is important to developing the effective protection technology of groundwater resources and eco-environment derogation.
