【摘要】：胜利一号露天煤矿首采区向西推进发展过程中,采场工作帮中央出现无煤区,过无煤区导致胜利一号露天煤矿在此期间生产能力接续困难、剥离量增加、剥采比增大、运距增加以及生产成本增加等问题。论文对胜利一号露天煤矿过无煤区开采方案进行了研究。通过收集露天矿钻孔数据、等高线、采场及排土场现状等基础数据,利用3DMine三维矿山软件构建了胜利一号露天煤矿地质模型,模拟过无煤区期间开采过程。提出过无煤区留“岛”方案与不留“岛”开采方案,研究了不同开采方案工程量、剥采比等的变化。提出了留“岛”搭桥、不留“岛”搭桥、留“岛”不搭桥、不留“岛”不搭桥四种过无煤区运输系统方案,确定了搭桥方案中合理的搭桥时间、桥体参数及桥体合理服务高度,并进行了运输系统优化。构建了开采方案综合评价模型,明确评价指标及其权重,确定了胜利一号露天煤矿过无煤区留“岛”搭桥开采方案。
[Abstract]:During the westward development of the first mining area of Shengli No. 1 opencast coal mine, there is no coal area in the center of the stope work, which leads to the difficulty of connecting the productive capacity, increasing the stripping amount and increasing the stripping ratio of Shengli No. 1 opencast coal mine during this period.Increase in distance and production costs and other issues.This paper studies the mining scheme of Shengli No.1 open-pit coal mine.By collecting the data of borehole, contour, stope and dump, the geological model of Shengli No.1 opencast coal mine was constructed by using 3DMine software, and the mining process was simulated during the period of no coal area.This paper puts forward the plan of "island" and "island" in coal free area, and studies the variation of engineering quantity and stripping ratio of different mining schemes.This paper puts forward four kinds of transportation system schemes of "island" bypass, not "island", "island", "island" and "island", and determines the reasonable bridging time, bridge parameters and reasonable service height of the bridge.The transportation system is optimized.The comprehensive evaluation model of mining scheme is constructed, the evaluation index and its weight are defined, and the mining plan of "island" bridge in Shengli No. 1 opencast coal mine is determined.
