Influence of Different Coal Discharge Methods on the Effectiveness of Coal Mining
Aiming at the mining effect of different coal discharge methods,based on the working conditions of the working face,a simulation analysis model is established based on PFC,and three types of single-round sequence,single-round interval and double-round sequence are simulated.Through the statistical analysis of the coal releasing process and coal releasing results,the results show that the best mining effect is obtained by using double-round sequential coal releasing,and the top coal extraction rate obtained by coal releasing at this time is the highest,and the gangue rate is the lowest.
