鲁西控煤构造特征及其演化分析

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，为炮 炭资源的进一步勘查提供了参考资料。

FEATURES AND EVOLUTION ANALYSIS OF COAL-CONTROLLING STRUCTURES IN WESTERN SHANDONG

Based on research on faulting and folding structures in western Shandong,the dominated features of coal controlling 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 coal field 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.
