摘要
针对采用传统采煤工艺及布置形式导致煤炭采出率低,造成煤炭资源浪费的问题,以A工作面的缓斜煤层为研究对象,在分析其地质、水文以及顶底板情况的基础上,以顺拉布置形式对俯采工艺进行优化,并提出俯采工艺的辅助措施,为提升缓斜煤层的煤炭采出率提供技术支撑。
Aiming at the problems of low coal recovery rate and waste of coal resources caused by traditional mining technology and layout form,taking the gently inclined coal seam of A working face as the research object,based on the analysis of its geology,hydrology,roof and floor conditions,this paper optimized the underhand mining technology by using the form of down drawing layout,and put forward the auxiliary measures of the underhand mining technology,which provided technical support for improving the coal recovery rate of gently inclined coal seams.
