王庄-常村断裂带新生性及其控水作用
|
摘要
针对厚覆盖层下新生的断裂构造难以发现的问题,采集各个时期不同目的的勘探资料,从地质构造、地貌特征、河流及其阶地、水化学、水动力特征等多角度多侧面的综合论证了潞安矿区王庄-常村断裂带的存在、新生性特征及其导、富水性,并认定了该新构造断裂带是矿区深部接受地表和上层水垂向越流补给的主通道之一、倾向上是矿区深浅部地下水反倾向流的一条主干通道、侧向上起到汇集更次级空隙水的集水廊道作用,澄清了地下水流向、水化学分布特征、富水性分区等一些混乱认识。指明其导水性对矿区的防治水和确定水源地有实际指导作用。
Basing the exploring data collected for different purpose at different time, the existence, newly-formed characteristics and water conductivity of Wangzhuang-Changcun faults zone are demonstrated from the aspects of geological structure, geomorphic feature, the river and its terrace and the characteristics of hydrochemistry and hydrodynamics. The analysis indicate the new tectonic fracture belt is one of the main channels that the deep mining area receive the leaking recharge from the surface and upper groundwater at vertical orientation, the main trunk channel of counterdip flow of the groundwater in deep at the tendency, and it plays the role of catchments channel that influx sublevel void water at the sides. Therefore, this paper clarifies some fuzzy ideas on the direction of groundwater, the distributional characteristics of hydrochemistry, and the water enrichment divisions and so on. The water conductivity of Wangzhuang-Changcun faults zone has important role for controlling water inrush and locating well.
