摘要
梅州市玉水溪硫铜矿是国有矿山企业,1985年建成投产以来,多次诱发地面塌陷,对附近村民的生命安全构成了严重威胁,并造成了较大的经济损失。文章在调查和广泛收集矿区勘探、矿井生产和地面塌陷发生情况等资料的基础上,通过对塌陷区周围地层岩性、地质构造、水文地质条件以及地面塌陷发生后后续地表变形、房屋破坏等情况的分析认为:矿山长期抽排地下水是地面塌陷的主要诱因;目前塌陷区西部相对稳定,东部不稳定;在矿山继续抽排地下水的条件下,塌陷区的灾情将继续发展,特别是东部区。这些认识为梅州市政府制定治理方案提供科学依据。
Yushuixi Sulphur-copper Mining Cooperation is a state-owned mining enterprise.Ever since this mine was founded and put into production,there have occurred many times of the collapses accidents which strongly threatened and affected the security and health of the villagers and caused serious economic loss.The authors researched and collected much information on the reconnaissance of the mine area,the production situation of the mine,and the ground collapses situation.According to the information we collected and our analysis on the lithology of the land layer around the collapse area,the geological structure characteristics, the hydrogeology condition,the surface ground deformation after the collapse accident,and the situation of the destroyed buildings,we can draw the following conclusion： The main reason that caused the collapse accident is the pumping and the draining of the ground water;At present,the western collapse area is stable,while the eastern area is not stable;If the underground water keep on being pumped and drained,it is very likely to cause accident again,especially for eastern area.Our research and information will provide the information for the government to establish the treatment project.
