孙村矿是一个开采多年的老矿,井田位于新汶煤田的中部,走向东西,平均走向长2500m,深部开采界限暂定-800m,井田内有7个可采煤层,属薄及中厚煤层,煤层倾角平均为25°,采用走向长壁式采煤法,回采工作而长度为100～150m,矿井开拓方式为斜井多水平主要石门开拓,主副井沿四层煤由地表至-210m,再经过暗斜井至-400m水平。一、二水平早已结束,第三水平(-400m)为生产水平,第四水平(-600m)为延深水平。
Suncun Mine is an old mine that has been mined for many years. The mine field is located in the middle part of the Xinwen Coalfield, heading east and west with an average length of 2,500m. The deep mining limit is tentatively set at -800m. There are 7 coal seams in the minefield, which are thin and medium thick Coal seam, seam angle average 25 °, using longwall coal mining method, the length of the recovery work 100 ~ 150m, mine development for the main shaft multi-level inclined shaft to open up the main and auxiliary wells along the four layers of coal from the surface to - 210m, then go through the dark shaft to -400m level. One or two levels have long been over, the third level (-400m) for the production level, the fourth level (-600m) for the deepening level.
