神宝矿区露天煤矿采场边坡失稳原因及治理措施研究
|
摘要
通过大量调查神宝矿区露天煤矿采场边坡及排土场边坡稳定状态,参考蒙东地区其他边坡滑动特点,总结了神宝露天矿采场边坡失稳的主要特征,分析了影响边坡稳定的因素。对影响边坡稳定的主要因素——软弱夹层进行了现场调查及室内试验,获取了物理力学参数。根据当地气候及现场实际情况,结合软弱夹层性质,分析了露天矿采场边坡变形失稳原因,并针对性的提出了防治措施,这些措施的实施保证了边坡的稳定性,取得了良好的效益。
Through a large number of investigations on the stability of the stope slope and the dumping ground slope of the open pit in the Shenbao mining area,and referring to the sliding characteristics of other slopes in the eastern Inner Mongolia,the main characteristics of the slope instability of the Shenbao open pit mine are summarized,and the factors affecting slope stability is analyzed. Field investigation and laboratory tests were conducted on the weak interlayer which is the main factors affecting the stability of the slope,and obtained physical and mechanical parameters.According to the local climate and the actual situation of the site,combined with the nature of the weak interlayer,the causes of the instability of the open pit slope are analyzed. The prevention and control measures were put forward in a targeted manner. The implementation of these measures ensured the stability of the slope and achieved good results.
