摘　　要：为进一步提升煤矿采煤工作面的生产效率和安全性,以某矿31051综采工作面为研究对象,在对其地质、煤层、瓦斯等情况综合分析的基础上,从成本、技术以及安全层面对比了炮采和综采的放顶煤开采方式的优劣性,并基于PFC2D仿真软件对综采放顶煤开采的最佳开采方式和采高、放煤步距等工艺参数进行优选。In order to further improve the productivity and safety of coal mining face,based on the comprehensive analysis of its geology,coal seam and gas,the advantages and disadvantages of gun mining and integrated mining roof coal mining are compared from the cost,technology and safety level;based on the PFC2D simulation software,the optimal mining method of integrated mining roof coal mining and process parameters,such as the mining height and the distance between the coal steps,are optimally selected.Based on the PFC2D simulation software,the optimal mining method and process parameters such as mining height and step of coal release are selected.
