摘要
柳泉煤矿含煤岩系属陆相沉积地层,煤层层数多、强度低,厚度、形态、煤层间距变化大,且遭受了成煤后的地质构造破坏,给生产带来了不利影响。本文阐述了利用煤岩层沉积特征在建立标志层、鉴别煤层层位、掌握煤厚变特点、分析煤层受力后断裂形态、判断构造寻找断失翼煤层等方面的成功应用,可为类似条件下的煤矿生产提供借鉴。
The coal - bearing formation of Liuquan Coal Mine belongs to continental deposit. The coal mine production is influenced frequently because of its multiple coal seams, low surrounding rock strength, big changing of coal thickness, structure, distance ＆ suffered by the post - coal - forming geological structure broken. This paper discussed the successful application of establishing marker bed, distinguishing the coal layer, finding out coal thickness changing features, analyzing coal seam fracture form ＆ seeking seam fault and so on by the coal rock depositional features, which provide a reference for the similar one.
