摘要:
岩溶矿山疏干降压显著改变矿区地下水流场,加剧岩溶塌陷及地面沉降等地质灾害,制约着矿山生产效益。本文针对贵州林歹矿区的岩溶塌陷问题,分析致塌因素及机理,结合专家打分法和层次分析法(AHP)确定各评价因子及其权重,继而利用地理信息系统(GIS)的空间叠加技术建立并验证矿区岩溶塌陷易发区评价模型。在此基础上,预测矿区延伸开采至1 040 m中段时,隔水底板在是否遭受破坏的这两种不同水动力条件下的岩溶塌陷易发区。结果显示,矿区的现状评价模型具有很高的精确度;矿山延伸开采过程中,隔水底板遭受破坏将给矿区带来不可挽回的灾难,其首要任务是保护隔水底板不受破坏。本文突破了矿山岩溶塌陷防治的瓶颈,也为矿山水害防治提供一种新方法,具有显著的经济效益和社会意义。
