When the mining of the previous section is about to end and that of the next section is about to start, the striping and the coal mining engineering must be optimized, in order to have a smooth mining transition. As an example, consider the mine engineering for transferring from one mining area to the next in Pingshuo Anjialing surface coal mine. The so-called L form project, the fanlike project and the dig ditch project are proposed. The three projects are compared with respect to the production stripping ratio, the time taken for transferring from one mine area to the next, the mine and overburden transportation distances and the economic benefit by adopting the projects. Based on the comparison, the L form project is adopted. For the determination of the next mining engineering location, we put forward a two section V-P curve connecting scheme, analyzing the production stripping ratio and the mining transition time, to finally establish the mining transition scheme. The annual stripping and mining coal engineering load of the two sections is optimized., authors=SONG Ziling¹, WANG Zhaodong^1,2, FAN Junfu¹, authorsList=SONG Ziling;WANG Zhaodong;FAN Junfu, authorCompany=1.

articleAbstract=近水平煤层露天煤矿划分成多个采区按顺序开采,上一个采区开采即将结束转向下一个采区开采时,需要做好两个采区在转向过渡期间的剥采工程优化安排,以保证转向过渡顺利.本文以平朔安家岭露天煤矿首采区向二采区转向开采期间剥采工程为例,提出了缓帮L型转向方案、缓帮扇形转向方案、重新拉沟开采转向方案,采用方案比较法分析比较了3个转向方案的生产剥采比、转向过渡时间、剥采运距及经济效益等,确定采用L型转向方案.在采区接续工程位置确定研究中,提出了多种两个采区V-P曲线接续方案,分析不同接续方案的生产剥采比、过渡时间等的变化规律,综合分析确定合理的转向过渡方案,并对两个采区的逐年剥采工程量进行优化.,
