摘　　要：我国大部分煤炭以厚煤层的形式埋藏于地下深处,综放开采是主要的开采工艺方式。在综采过程中,不同的放煤方式对煤层的采出具有重要影响。针对不同放煤方式的影响作用进行仿真分析,可为厚煤层放煤方式的选择提供一定参考。结果表明,单轮间隔放煤具有较好的开采效果,是更适合厚煤层开采的放煤方式。Most of China′s coal is buried deep underground in the form of thick coal seams,and fully mechanized top coal caving is the main mining process.In the process of fully mechanized mining,different coal drawing methods have a significant impact on the extraction of coal seams.Simulate and analyze the impact of different coal mining methods,can provide some reference for the selection of coal mining methods in thick coal seams.The results indicate that single wheel interval coal caving has a good mining effect,and is a more suitable coal caving method for thick coal seam mining.
