摘要 某矿山小区“3.28”滑坡灾害严重威胁着下方居民的生命安全,通过现场勘查发现滑坡体南北两侧又发育了2处不稳定边坡,宽度分别为31 m和30 m。
为了对小区西侧边坡进行系统研究,应用MSARMA法和基于该方法开发的边坡工程稳定性MSARMA法评价分析系统,对小区1#不稳定边坡进行了稳定性定量评价和影响因素敏感性分析,为小区西侧边坡加固和远程监测方案设计提供了科学依据。
Abstract:
“3.28” landslide disaster of a Mine Quarter seriously threats the life safety of the resident below,through the geological survey,two more unstable slopes with the widths of 31 m and 30 m respectively were developed in south and north sides of the slip mass.To study the west slope of the neighborhood systematically,MSARMA Analysis and Evaluation System of Stability based on the MSARMA method had been applied to process the quantitative evaluation and sensibility analysis of No.1 unstable slope of quarter neighborhood,which provided scientific bases for reinforcement scheme and monitoring program of west slope of quarter n
矿山水的来源主要有:
地下水、地表水、自然降雨、老窿水(废弃的积水井巷)。
水害及后果
(1)采掘工作面突水。
突水具有很强的突发性,可能造成人员伤亡和财产损失。
(2)采掘工作面或采空区透水。
各种通道使采空区与储水体连通,大量水体直接进入采空区,导致采空区、巷道甚至矿井被淹,因而可能造成大量的人员伤亡和财产损失。
(3)地表水体或突然大量的降雨进入井下。
通过裂隙、溶洞、废弃巷道、透水层、地表露头等与采空区、巷道、采掘工作面连通,使大量的水体直接进入采空区再进人人员作业场所,或直接进入作业场所,从而形成采空区、巷道、采掘工作面甚至矿井
