大唐胜利东二号露天煤矿首采区工作帮推进方案

Scheme of working slope advance in the first mining area of Datang Shengli east No.2 open-pit coal mine

胜利东二矿二期工程初步设计首采区采用的是西推方案,该方案基于现采场位置和拉沟长度,由于目前南帮存在断层、弱层等地质构造,按原二期初设西推方案最终无法保证边坡稳定,且南帮还将布置有半连续工艺的胶带运输系统,南帮滑坡将对生产造成了极大的影响。因此,提出了二期首采区西北推与西推方案进行重新比选。

Based on stope position and slotting length, the second phase project preliminarily designs first mining area which adopts westward advance scheme. Owing to south slope existing fault and weak layer, the former westward advance scheme of second phase project cannot ensure slope stability and south slope will layout belt transport system of semi-continuous process. South slope landslide will have great effect on production. Therefore, the article presents the first mining area of second phase project northwest advance scheme and westward advance scheme and carries out re-selection.
