摘要：
摘 要：随着采深和煤层倾角的加大，三道岭露天煤矿采用陡帮作业方式，并确定了露天煤矿的陡帮作业方式，结合露天煤矿的实际情况，分析和确定了陡帮作业参数，增大了工作帮坡角，减小了生产剥采比，提高了经济效益。
Abstract:
Abstract: With the increase of mining depth and dip angle of coal seam, Sandaoling Open-pit Coal Mine adopts steep slope mining operation way and determines the steep slope operation way in open-pit coal mine. Combining with the actual situation of the open-pit coal mine, the article analyzes and determines the steep slope operation parameters, increases the working slope angle, reduces the production stripping ratio, and improves the economic benefit.
