Analysis and protection of slope stability in open-pit coal mine
Because the coal seam of Jinzhengtai open-pit coal mine exists deeply,lead to the side of the large amount of coal overburden.The stability of side slope is an important prerequisite to ensure the safety of coal seam mining.Therefore,this paper analyzes and calculates the stability of the slope in each mining area of the coal seam,and obtains the minimum Factor of safety under the corresponding slope angle.At the same time,monitoring points and corresponding protective measures are arranged in the slope to effectively ensure the stability of the slope in coal mining.
