摘要 韩城矿区是渭北岩溶强发育区,岩溶水富水性极强。通过大量地质资料分析,结合现场调查,对该区碳酸盐岩岩溶形成及其发展机理进行了研究,结果认为,影响岩溶化作用因素主要为岩性、构造及水动力。而在这些因素中,以构造影响岩溶化作用最为显著,它控制着岩溶裂隙及其径流带的发育程度和含水构造的形成以及水文地质单元的划分;岩性及其结构的差异对岩溶作用也有较大的影响,不同岩性,相同岩性不同组构其岩溶化作用的强度不尽相同;水动力条件是岩溶发育的又一外因,它决定着岩溶作用的强弱及其溶隙网络的形成。可见,韩城矿区岩溶作用及其水文地质特征是地质构造场、岩性结构场和地下水动力场三者叠加作用的结果。 Hancheng mining area is located in Weibei karst area, the karst has extremely strong in enriching water. Through a large amount of geological data analysis, combined with field investigation, the formation and development mechanism of the carbonate karst in the area were studied. The results showed that the main factors affecting the melting of the area are lithology, structure and water power. For these factors, the structure impact is the most significant, which controls the development of karst fracture and its runoff belt and the formation of water cut structure and the division of hydrogeological units, the difference of lithology and structure of different rock, the same lithology of different groups of the same. It can be seen that the karst function of Hancheng mining area and its hydrogeological char-acteristics are the result of the superposition of the three effects of the geological structure, the structural field and the groundwater dynam-ic field.
