摘要
为进一步提升综采工作面的煤炭的回收率和煤炭质量,以某矿4501工作面3号煤层为例,在分析其地质、水文以及煤层等条件的基础上,对所采用的放顶煤开采工艺下对应的放煤高度、放煤步距以及放煤方式进行优化确定,为其他开采工艺下采煤参数及工艺参数的优化确定提供指导。
In order to further improve the coal recovery rate and coal quality of fully mechanized working face,taking No.3 coal seam of 4501 working face of a mine as an example,based on the analysis of its geological,hydrological and coal seam conditions,the corresponding caving height,caving step and caving method under the adopted caving mining technology are optimized and determined,which provides guidance for the optimization of mining parameters and process parameters under other mining technologies.
