大倾角、大间距煤层采区联合布置系统设计优化

Optimization design of the mining area combined layout of large dip angle and large space coal seam

大倾角煤层采区轨道、运输机下山布置为穿层,需全岩掘进造成单进低、开拓准备时间长、采掘接续紧张,同时倾斜仰采工作面向上运煤困难。通过水平石门将大间距煤层联合布置,实现排水、运输集中化,优化准备工程,减少岗位人员,缩短采区准备时间,缓解采掘接续,降低万吨掘进率,达到降本提效的目的。

The large dip angle coal seam mining,the rail and the transport dip entry track layout in the different rock,digging along the rock,due to excavation progress is low,the time of development is long,caused the tension between preparation and production,at the same time also caused the difficult of the coal transportation upward working face,Combined layout make the big distance coal seams to connect with the crosscut,realizes the centralized drainage,transportation,optimization of preparation,reducing staff,shorting the preparation time,alleviate the tension between preparation and production,reduce the million ton drivage rate,achieve the aim of high efficiency.
