摘要 从2011年开始,东明露天煤矿逐步在生产实践过程中对端帮煤陡帮开采技术进行研究和探索。为了探究陡帮控制开采技术在东明露天煤矿的有效应用,2017年进行了全面深入的研究。主要通过对南端帮的地质条件、边坡暴露时间、边坡安全系数等因素的分析、现场监测、计算。仅2018年多回采煤量达36.26万t,创造直接经济价值5 439万元。南端帮陡帮控制开采技术在东明露天煤矿生产中的成功应用,很大程度上提高了经济效益和煤炭资源的综合开采水平。 Since 2011,Dongming opencast coal mine has carried on the research and exploration to the mining technology of the steep side coal in the process of production practice step by step.In order to explore the effective application of the control mining technology of the steep slope in Dongming open pit coal mine,an in-depth study has been carried out in 2017 in all-round way.In this paper,the geological conditions,exposure time and safety factor of the southern slope are analyzed,monitored and calculated on the spot.Only 2018 more than three hundred and sixty two thousand five hundred and ninety nine tons of coal production,creating a direct economic value of 54.39 million yuan.The successful application of the control mining technology in Dongming opencast coal mine has greatly improved the economic benefit and comprehensive mining level of coal resources.
