摘要
为了查明梁花园井田的基本构造,指导本区煤炭勘查开发,应用滑脱构造理论,结合钻孔资料和地震剖面,对区内地层、煤层、断层等特征进行了详细对比、综合分析和系统研究,否定了以往对该井田(垒-堑式)构造的看法,并取得新的认识。梁花园井田的主体构造是一个滑脱构造;控制梁花园井田的东、西两条大断层(原F1、F8)实际是同一条向下凹的弧形滑脱断层;梁花园井田实际是一块较为完整的矿产地。该结论扩大了梁花园井田煤炭储量的估算范围,避免了因认识误差造成的资源浪费。
In order to find the basic structure framework of Lianghuayuan field for coal resources exploration, the comprehensive and systematic analysis methods are performed by using detachment structure theoretical explanation and combined with borehole data, logging data, strata, coal seams and faults were compared. The obtained resuits indicated that the previous conclusions of horst-graben structures are not correct. The new review is that a detachment structure is the main structure in Lianghuayuan field; two faults （F1 and F8） in eastern and western Lianghuayuan field are the same concave arc-shaped detachment structure. The Lianghuayuan field is actually a whole mineral production area according to the regional geological background and dynamic feature. These obtained results are of more significance for expanding coal reserve calculation scale and avoiding resources loss.
