徐州市九里区大孤山露采矿场,地处城市中心,1999年关闭后,留下众多的地质灾害隐患。以区域地质条件为基础,对该区可能产生的倾斜式崩塌、楔体滑塌、岩溶塌陷三种主要矿山地质灾害的发育特点进行了描述,据此提出了有针对性的坡率法、喷射混凝土、预应力锚索、注浆加固、截排水、重力档墙、整坡七种防治措施,并对其生态修复工程技术措施进行了解析。九里区大孤山露采矿场地质灾害的处理方法为徐州市矿山治理工作提供了借鉴。
Duli Mountain in Guli District, Xuzhou City, exposed mining, is located in the city center, closed in 1999, leaving many hidden dangers of geological disasters. Based on the regional geological conditions, the development characteristics of geological disasters such as inclined collapse, wedge slump and karst collapse in the area may be described. According to the above, some specific methods of slope rate, jetting Concrete, prestressed anchor cable, grouting reinforcement, cut-off drainage, gravitational file wall, whole slope seven kinds of control measures, and its ecological restoration engineering technical measures were analyzed. The treatment method of geological disasters in Dagushanlu mining field in Jiuli District provides reference for mine management in Xuzhou.
