霍林河一号露天煤矿采区过渡优化研究

Research on mining area transition optimization in Huolinhe No.1 Open-pit Mine

针对霍林河一号露天煤矿南区即将到界,需向北延伸的现状,在仔细分析采区过渡方式选择原则及影响因素的基础上,确定多种可行方案,采用模糊综合评价法,建立了采区过渡方案优选模型,对几种可行方案进行了优选分析,经过综合评价,最终确定留沟缓帮方案为最优方案。

Aiming at the situation of south area extending to north in Huolinhe No. 1 Open-pit Mine, on the basis of carefully analyzing the mining area transition mode selection principle and influenced factors, this article determines multiple feasible solutions. Using the fuzzy comprehensive evaluation method, establishing mining area transition plan optimization model, the article carries out the optimal analysis on several feasible schemes, finally determines that the scheme of retained ditch with gently inclined slope is the optimal one through comprehensive evaluation.
