淮北临涣矿区太原组灰岩含水层富水性评价

Water Abundance Assessment on Taiyuan Formation Limestone Aquifer in Huaibei Linhuan Mining Area

在充分收集淮北临涣矿区水文地质资料的基础上,对太原组灰岩的富水性进行了分析评价。研究结果表明:临涣矿区太原组灰岩岩溶在平面上和垂向上整体发育较差,局部岩溶发育;灰岩富水性整体弱,局部较好;岩溶发育程度有随埋深减弱的规律,相对应有富水性随埋深的增加而减弱。矿区太灰含水层整体属于"高承压,弱富水"型含水层。

Based on collecting the hydrogeological data of Linhuan mining area in Huaibei sufficiently, the water abundance of limestone of Taiyuan Formation was analyzed and assessed. The results showed that the karst limestone of Taiyuan Formation in Linhuan mining area developed not well in level and vertical and the karst developed partly. The water abundance of limestone is weak on the whole and relatively good partly. The degree of development of karst weakens along with the depth as well as the water abundance weakens along with the increase of depth correspondingly. The aquifer of limestone in Taiyuan Formation in this mining area belongs to the aquifer of high pressure and weak water abundance.
