Taking Gaojialiang Coal Mine as an example,this paper explores the safe and efficient mining technology of the large-inclination working face in coal mines.First,the project overview is analyzed,and the simulation analysis method is used to discuss the activity laws of the overlying strata in the stope of the large dip face.When the mining depth is different,the movement characteristics of the overlying strata in the stope change,and the overlying strata in the direction of the working face tilt are summarized.Then,a safe and efficient mining technology system for the large-inclination working face is established.The specific application methods of the stability control technology for the large-inclination working face,the control technology for preventing sheet side roof collapse,and the safe and efficient fault crossing technology are introduced successively.Finally,the application effect of this technical system is judged through the actual measurement of mine pressure.The results show that the mining technology system proposed in this paper can effectively prevent safety accidents in mining operations on large-inclination working faces and ensure the safe,efficient and scientific advancement of mining operations.
