Research on Mining Parameters of Steeply Inclined Coal Seams
In recent years,due to the continuous mining of coal resources and the increase in mine depth,the geological conditions of coal seams have been continuously deteriorating,especially in the mining of steeply inclined coal seams,which have extremely high requirements for mining technology.Based on the current status of mining technology in steeply inclined coal seams,a new type of slope short arm mining technology is proposed by analyzing the mining parameters of steeply inclined coal seams,providing reference for the mining of such complex coal seams.
