近距离煤层工作面跨层出煤系统设计

Design of Cross-layer Producing Coal System in Close Coal Seam Working Face

同煤集团煤峪口矿11-12~#合并层307盘区8702下工作面在前期掘进期间因受煤层自燃影响,被迫封闭。火区熄灭后该矿通过利用其下部14~#层巷道对工作面进行启封并重新设计出煤系统,保证该工作面资源顺利回收,该设计对类似条件下工作面设计具有一定参考价值。

8702 down working face at 307 panel in 11-12~#merge Layers in Meiyukou Coal Mine of Datong Coal Mine Group was forced to close during the early tunneling due to the influence of coal seam spontaneous combustion. The working face was unsealed by using the 14~#layer of roadway in this coal mine after the fire was extinguished in this area and producing coal system was redesigned in this paper, which can ensure that the mining resources was recycled, and the design had a certain reference value for the design of working face under the similar condition.
