摘要
通过对矿区地层、构造以及水文地质条件的分析,认为寒武—奥陶系岩溶裂隙含水层是矿区的主要含水层。岩溶水受地层岩性、构造的作用明显,岩溶发育程度在矿区呈现出西弱东强,浅部强、深部弱的发育规律。岩溶水动态受大气降水和矿井排水的双重控制,大气降水是岩溶水的主要补给来源,矿井排水是主要排泄方式,水位动态属于降水—矿排型。在天然状态下,岩溶水主要接受南部露头区大气降水的补给,然后自南向北、自西向东径流,经过新中—三李一带的岩溶水强径流带,在三李一带以岩溶大泉的方式向外排泄。
Through mining area stratigraphic, structural and hydrogeological condition analyses, considered that the Cambro-Ordovician karstic fissure aquifer is the major aquifer in the area. Karstic water is obviously controlled by lithologic and structural characteristics. Development extent of karst in the mining area presents regular pattern of strong in east, weak in west; strong in shallow part, weak in deep part. Karstic groundwater regime is dually controlled by atmospheric precipitation and mine drainage. The atmospheric precipitation is the main recharge source, while the mine drainage is the main discharge mode, water level dynamic state belongs to precipitation-mine drainage type. Under natural state, karstic water is mainly recharged by atmospheric precipitation from southern outcropped area, then runoff from south to north, west to east through a strong runoff zone in Xinzhong-Sanli district, discharged outside to take form of karstic large springs in Sanli district.
