摘　　要：针对不同放煤方式的开采效果,依据工作面的工况,基于PFC建立仿真分析模型,模拟了单轮顺序、单轮间隔及双轮顺序3种放煤方式。通过对放煤过程及放煤结果的统计分析,结果表明,采用双轮顺序放煤得到的开采效果最佳,此时放煤得到的顶煤采出率最高,含矸率最低。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.
