基于离散元对放煤方式的研究

Research of Caving Methods Based on Discrete Element

介绍了单轮间隔放煤、单轮顺序放煤和多轮间隔放煤3种不同的放煤方式,利用离散元PFC3D软件对3种放煤方式进行模拟,给出了模拟结果,并依据模拟结果分析了3种不同放煤方式的优缺点,提出了一些加以改进的意见。

The paper introduced three kinds of different methods of caving methods,namely single-interval caving,single-order caving and multi-interval caving.It used discrete element PFC3D software to simulate the three kinds of caving methods, obtained the simulation results,and analyzed advantages and disadvantages of the three kinds of different methods based on the simulation results.It also proposed some suggestions for improvement of caving methods.
