【摘要】 为查明工作区断层的性质、特点及延伸情况,了解2号、11号煤层的分布范围,根据勘探区的地震地质条件,结合前期的试验工作成果,确定了地震勘探的工作参数,采用二维地震构造解译法,对获得的勘探数据资料进行处理和解释,结果表明:勘探区2号和11号煤层的赋存形态宏观上为一向SE方向倾的单斜,埋深主要受断裂系统控制;东部埋深大,西北部埋深小,并发育有两个规模较大的褶曲—背斜(S3)、向斜(S1、S2);解释断点7个,利用其中7个断点组合断层两条,落差均大于100 m的(Fd1,Fd2),均为可靠正断层;根据区内反射波组的发育特征,圈定了11煤层控制程度较差的区域,初步认为本区无煤层缺失区。更多还原

【Abstract】 In order to ascertain the nature, characteristics and extension of faults in the working area, and to understand the distribution range of the No.2 and the No.11 coal seams, we determined the working parameters of seismic exploration according to the seismic geological conditions of the exploration area and combined with the previous experimental results, and used the two-dimensional seismic structure interpretation method to process and interpret the obtained exploration data. The result shows that the main mineable seams in the exploration area were monoclinic dipping toward SE, and the buried depth was mainly controlled by the fault system. The eastern part was buried deep, the northwestern part was buried deep, and the deepest point was in the eastern part of the exploration area. The occurrence of the strata in the area was relatively large, with an inclination of about 4～30°and the maximum inclination was located in the central part of the exploration area. Seven fault points were interpreted, and two faults were combined with seven fault points with a drop greater than 100 m(Fd1, Fd2),both of which were reliable normal faults, and one isolated fault pointed with a drop greater than 20 m(Fd1-1).On this basis, there were two synclines(S1, S2)and one anticline(S3)with larger secondary folds.更多还原
