摘要
薄煤层作为一种极为常见的煤层赋存方式,由于回采工艺的不完善而长期未得到有效利用,特别是对于含矸的薄煤层而言,回采难度更加巨大。结合具体工程实际在设备选型和改进的基础上,对如何实现含硬矸煤层的有效开采做出分析,希望能为其他矿井薄煤层资源的有效开发提供借鉴与参考。
As a very common kind of coal seam occurrence mode,thin coal seam has not been effectively used for a long time due to the imperfect mining technology.Especially for thin coal seam containing gangue,extraction is more difficult.Combined with the specific engineering practice and based on equipment selection and improvement,this paper analyzed how to realize effective mining of the coal seam containing hard gangue,hoping to provide reference for the effective development of thin coal seam resources in other mines.
