磁窑沟煤矿13号煤层工作面综放开采三机设备选型研究

Study on the selection of three-machine equipment for fully mechanized caving mining in No.13 coal seam working face of Ciyaogou Coal Mine

磁窑沟煤矿13号煤层为厚度10 m以上的特厚煤层,采用综放方法进行机械化开采,为保证综采工作面生产效率以及安全运行,根据综采工作面和地质构造情况,在分析“三机”配套原则的基础上,对磁窑沟煤矿13号煤层工作面“三机”参数进行计算,并根据计算结果进行“三机”选型,为其他特厚煤层的综放开采提供借鉴。

The No.13 coal seam in Ciyaogou Coal Mine is an extra-thick coal seam with a thickness of more than 10 m.The fully mechanized caving method is used for mechanized mining.In order to ensure the production efficiency and safe operation of the fully mechanized working face,according to the fully mechanized working face and geological structure,based on the analysis of the matching principle of the“three machines”,the“three machines”parameters of the working face of No.13 coal seam in Ciyaogou Coal Mine are calculated,and the“three machines”are selected according to the calculation results,which provides reference for the fully mechanized caving mining of other extra-thick coal seams.
