Geological study identifies coal layers and characteristics in Shanxi coalfield, suggesting safety measures for extraction.
本文以山西省大同煤田北辛窑井田为研究对象,阐述其地层、构造、含煤地层、可采煤层、煤质煤岩特 性及水文地质条件。井田地层自奥陶系至第四系均有发育,主要含煤地层为石炭系上统太原组;构造总体呈背斜,受 区域构造影响,断层发育,共81条正断层,构造复杂程度中等。井田赋存2、5、6号三层可采煤层,2、5号稳定,6号 较稳定;煤类以长焰煤和气煤为主,适宜作动力和气化用煤。综合评定地质类型为中等,开采需关注断层导水等问题, 建议用多种物探手段精细勘查以保障安全生产。
