摘要
在对安庆市怀宁县黄岭塌陷区地质环境条件、岩溶发育特征以及岩溶水动态变化特征简要分析的基础上,选择NaCl作为示踪剂,开展地下水示踪试验,结果显示在JJ1孔北侧-宣家屋南-潘家老屋南-洞山一带有一个地下水分水岭,分水岭之北为某铜矿疏干排水降落漏斗范围,分水岭之南为天然流场和开采井漏斗范围。该结论的得出有助于加强岩溶塌陷灾害防治的针对性。
Based on the hydrogeological investigation of karst, tracer tests were conducted, the results showed that a watershed divide near the north of JJ1-South of Xuan jia wu-South of Pan jia lao wu-Dong shan mountain area. watershed North for copper mine drainage funnel range, watershed south of the natural flow and mining wells funnel range. The conclusion is helpful to strengthen the pertinence of karst collapse disaster prevention.
