摘要

本井田含煤地层为二叠系山西组和石炭系太原组，煤系地层平均总厚280.92m。地层特征矿井综合柱状如图1-2所示。共含煤26层，可采与局部可采8层，平均总厚10.46m，含煤系数为3.72%。其中，主要可采煤层为3上、3下及16上、17煤平均总厚为8.02m，占可采煤层总厚的76.67%；3上、3下煤层厚度较大，平均厚度达5.86m，占可采总厚的58.4%。

井田划分为一个水平。采用立井开拓。主井装备箕斗，副井装备罐笼。大巷采用胶带运输机运煤，辅助运输采用固定式矿车运输。矿井通风方式为中央边界式通风。矿井涌水量不大，正常涌水量为140m3/h，最大涌水量为220m3/h。矿井煤尘无爆炸危险性，且煤层不易自燃。

关键词:井田开拓；通风；采煤工艺
