Upward horizontal cut-and-fill mining process optimization based on CMS empty area detection technology

为了解决某矿山顶板岩层破碎、采场稳定性难以控制的问题,以现有矿山开采技术条件为基准,从待充填空区三维激光探测、充填材料的选择、充填浓度配比的优化、料浆的制作与输送、上向分层充填工艺的改进等角度对充填采矿法进行优化。通过多环节的技术更新优化,有效降低了该矿山的资源浪费、财产损失以及安全生产事故隐患。对该矿上向分层充填采矿法的充填工艺和材料进行了阐述,以期对类似复杂工况条件的矿山起到一定的参考作用。

To solve the problems of broken roof rock mass and poor stope stability of a certain mine,based on the existing mining technology conditions,the 3D laser scanning technology was used to accurately detect the empty area to be filled.Furthermore,the ratio of the filling materials and the filling concentration was optimized,the production and conveying process of slurry was optimized,and the filling process was improved.Through the technological update and optimization of multiple links,the waste of resources,the property losses and the potential accident of production safety in the mine were effectively reduced.In this paper,the filling process and materials of the improved cut-and-fill mining method were described in detail,hoping to play a certain reference role for mines with similar complex working conditions.
