露天矿坑灰场岩质高边坡的稳定性评判与治理

露天矿坑边坡及排土场边坡,由于地质构造、采矿活动等原因极易诱发滑坡、塌陷、地面变形等地质灾害。莱州电厂拟采用仓上金矿矿坑作为灰场，边坡的长期稳定性有着重要的意义。通过对仓上矿坑边坡的工程地质调查与分析，总结了灰场边坡的地质条件和构造情况。在现场监测的基础上，对矿坑边坡的稳定性进行了详细的分析，所得的结果能较理想地反映该矿坑边坡的实际稳定程度，并根据工程的实际情况提出了切实可行的治理方案。

Controlling and Evaluation on High Rock Slope Stability of Open-pit for Ash Storage

Slopes of open-pit mine and ash storage are likely to result in the geological disasters of landslides，collapse，ground deformation and so on，due to its geological structure and mining activities，etc.Laizhou Power Plant is going to use the open-pit of Cangshang gold mine as ash storage field.Therefore，the long-term stability of the slope is of great significance.Through the geological investigation and analysis of open-pit mine slope of Cangshang Mine，the geological and tectonic conditions of ash slopes are summarized.On the basis of field monitoring，the stability of the slopes is analyzed in detail.The estimated results can better reflect the actual stability of the open-pit slope.Feasible treatment scheme is put forward according to the engineering practice.
