摘要
通过勘探表明,拉芒煤矿含煤地层时代属上石炭统乍奎组,煤层主要赋存于乍奎组第二段中亚段和上亚段,以碎屑岩沉积为主,局部区域含火山碎屑岩、火山岩,可对比煤层14层,区域上可采煤层6层。区内共见8条断层,不同断层影响程度不尽相同。
The survey shows that coal bearing formation of the Lamang coal deposit belongs to the Upper Carboniferous Zhakui Formation.The coal seams are mainly located in the Middle and Upper Submembers of the Second Member of the Zhakui Formation.The coal seams are mainly composed of clastic sedimentary rock and a small amount of pyroclastic rock and volcanic rock.8 faults developed in the mining area have different effects on the coal beds.
