摘要
基于三维地震数据体,通过时间剖面、波阻抗反演及属性分析等解释技术,对主要煤层的构造、煤厚、冲刷及缺失范围等4个方面进行分析。结果表明,研究区主要煤层整体呈走向NNE、倾向NWW的单斜形态,西北部发育有微小褶曲;发现落差小于5 m的正断层2条;煤厚自东向西呈厚—薄—厚的变化趋势,变化幅度微弱;区内未发现古河床的冲刷现象;东北部和东南部出现3-1煤的缺失,但范围较小。研究区煤系地层构造程度简单,煤层空间赋存稳定,开采地质特征优良,有利于矿井生产开拓。
Based on three dimensional seismic data,the structure,thickness,erosion and missing range of main coal seams were analyzed by means of time profile,wave impedance inversion and attribute analysis.The results showed that the main coal seams in the study area were in the monoclinic form of NNE and NWW,and there were small folds in the northwest.Two normal faults with drop less than 5 m were found;the coal thickness showed a trend of thickness-thin-thickness from east to west,and the change range was small.No erosion phenomenon of ancient riverbed was found in the area.There was a lack of No.3-1 coal in the northeast and southeast,the range of which was small.The structure of coal measures strata in the study area was simple,the space occurrence of coal seams was stable,and the mining geological characteristics were excellent,which was beneficial to the production and development of the mine.
