摘　　要：为解决大倾角厚煤层开采时由于采煤工艺参数不合理所导致的单产率低、回采周期长以及搬家频繁的问题,以21051综采工作面为例在对其煤层、地质条件等进行综合分析的基础上,基于PF2CD软件构建了数值模拟仿真模型对不同开采工艺下的工作参数进行分析,为21051综采工作面的实际开采奠定了扎实的基础。In order to solve the problems of low yield,long mining cycle,and frequent relocation caused by unreasonable mining process parameters during the mining of thick coal seams with large inclination angles,taking the 21051 comprehensive mining face as an example,a numerical simulation model was constructed based on PF2CD software to analyze the working parameters under different mining processes,laying a solid foundation for the actual mining of the 21051 comprehensive mining face.
