FEATURESAND EVOLUTION ANALYSIS OF COAL-CONTROLLING STRUCTURES IN WESTERN SHANDONG

摘要: 在对鲁西断裂、褶曲构造研究的基础上,分析了构造控煤的主要特点及构造演化特征,结果表明:由于沂沭、聊考断裂长期的左行平移,控制了煤田构造,形成鲁中箕斗型断块构造和鲁西南的堑垒型断块构造,使含煤地层遭受到不同程度的破坏。今后找煤勘探应在构造叠加的地区进行,为煤炭资源的进一步勘查提供了参考资料。

Abstract: Based on research on faulting and folding structures in western Shandong, the dominated features of coal control-ling structures and their evolution are analyzed.The results show that as the result of long range left-separation faulting action of Yishu and Liaokao faults, the structures in coalfield are controlled by that and the skip-like block structures in central area, as well as the horst and trough combination type block structures in southwestern Shandong are formed, due to which the coal-bearing strata are fractured.It is suggested that the structure-stacking area must be the target area for coal exploration.The research results are therefore the foundation for further exploration.
