摘　　要：以平朔东露天煤矿端帮边坡现状为研究背景,基于岩质边坡土力学理论,结合端帮边坡因上下岩石风化程度以及自身岩性不同的特点,根据陡帮开采理论以及相关应用案例,提出下部边坡外扩陡帮开方法和边坡内缩陡帮开采方法。利用GEO-Slope数值模拟软件,计算得出陡帮边坡的稳定性系数,并对危险边坡提出滑坡防范性措施,证明下部边坡外扩陡帮法开采方案的可行性。形成了适合该露天矿端帮陡帮开采的技术体系,为后续陡帮开采推广奠定了基础。Taking the current situation of the end slope in Pingshuo East Open-pit Coal Mine as background,based on the theory of rock slope and soil mechanics,combining with the characteristics of the end slope due to the weathering degree of the upper and lower rocks and its own different lithology,according to the theory of steep slope mining and related application cases,the article puts forward the method of expanding steep slope outside the lower slope and the method of mining steep slope inside.Using GEO-Slope numerical simulation software,the article calculates the stability coefficient of steep slope,and puts forward the preventive measures for the dangerous slope,which proves the feasibility of the mining scheme of expanding the steep slope outside the lower slope,forms the technical system suitable for the end slope and steep slope mining,and lays a foundation for the subsequent steep slope mining promotion.
