Analysis of the Influence of Different Coal Mining Processes in Fully Mechanized Top Coal Mining
Fully mechanized top coal caving mining is an important coal caving process widely used,especially for the mining of steeply inclined coal seams,which can improve the mining level of coal mines.Theoretical and experimental analysis was conducted on the impact of different coal drawing techniques on coal production and quality in top coal caving mining.The results showed that multiround interval coal drawing is the best coal drawing method in fully mechanized top coal caving mining in steeply inclined coal seams.At this time,the recovery rate and raw coal production are the highest,and the gangue content is relatively low.
