一、矿井简介沿江矿开采煤层系大乔地煤组下部,为晚三迭纪山间盆地陆相沉积,基底凹凸不平,煤层结构复杂,分岔、合并频繁。含煤地段总厚840m,共含可采煤层4层,即44一中、平均厚1.61m,45—上、平均厚2.33m,46—2,46—中,平均厚3.17m,其中45—上为全井可采的主要煤层,其余均是局部可采煤层。
First, the mine profile Coal mining along the Yangtze River coal seam Daqiao coal in the lower part of the late Triassic mountain basin continental deposition, uneven basement, complex coal seam structure, bifurcation, merger frequently. The coal-bearing section has a total thickness of 840m and a total of 4 layers of coal-bearing coal seams, ie, 44 middle ones, with an average thickness of 1.61m and 45- with an average thickness of 2.33m and 46-2 and 46-, with an average thickness of 3.17m, of which 45 - The main coal seam is fully recoverable on the whole well, and the rest are all locally recoverable coal seams.
