告成煤矿13采区的所有工作面在-100m回风大巷附近煤层厚度可达20m左右,然而在工作面回采过程中为了尽量减少回采工作面对回风大巷和运输大巷的影响,13采区以往已回采的工作面在距-100m回风大巷40m左右都留有保护煤柱,煤炭资源没有得到有效的开采,通过延长13141工作面的倾向长度,使近80m的回采巷道得到充分利用,工作面可采期增加了将近两个月,增加产量近50kt,提高了煤炭资源的回收率。

Seam thickness near-100m wind tunnel is up to about 20m at all faces of No.13 Mining Area in Gaocheng Colliery.In the course of face stoping,in order to reduce the influence of mining face on ventilation roadway and transportation roadway,protective coal pillars are remained at about 40m from-100m ventilation roadway of stoping face of No.13 Mining Area,which leads to coal resources not effectively exploited.Extending the length of the tendency of 13141 Face enables nearly 80m stoping roadway to be full utilized,the face mining period to be increased nearly 2 months,production to be increased by nearly 50.000 tons,which improves the recovery of coal resources.
