摘要
基于北平坝排土场边坡变形失稳制约着小龙潭露天矿开采与安全稳定的现状,研究了北平坝排土场边坡变形机制,提出了通过地下水疏排、防洪沟改移等措施对边坡变形进行治理。结果表明:所采取的治理措施减缓了边坡的变形速率,地下水位得到合理控制,区域地表位移速率显著降低,盲沟涌水量增大并趋于稳定,边坡稳定性系数从1.008提升至1.497,边坡由欠稳定状态改善为稳定状态。
Based on the current situation of slope deformation and instability restricting the mining and safety stability in Beipingba dump of Xiaolongtan Open-pit Mines,the article studies the slope deformation mechanism of Beipingba dump and proposes the measures such as groundwater drainage and flood control ditch relocation to control the slope deformation.The results show that the adopted governance measures slow down the deformation rate of the slope,the groundwater level is reasonably controlled,the regional surface displacement rate is significantly reduced,the blind ditch inflow increases and tendsto stabilize,and the slope stability coefficient increases from 1.008 to 1.497,slople improvement from unstable state to stable state.
