摘要
在对厚煤层开采过程中,不同的采高对煤岩的运动有重要影响,从而影响煤炭开采的质量.采用PFC2D仿真软件,模拟分析了不同采高时煤岩的运动过程.结果表明,当采高为3m时,煤岩能够充分流动,煤炭采出率最高,含矸率最低.
Abstract
In the process of mining thick coal seams,different mining heights have a significant impact on the movement of coal and rock,thereby affecting the quality of coal mining.Using PFC 2D simulation software,the movement process of coal and rock at different mining heights was simulated and analyzed.The results showed that when the mining height was 3 m,the coal and rock could fully flow,and the coal extraction rate was the highest and the gangue content was the lowest.
