摘要
芦店滑动构造是河南省西部嵩(山)箕(山)地区滑动构造群中的一个典型实例。其主要表现为双期相向滑动的叠加、两类滑动构造模型的拚合及两种动力因素的作用。通过对其综合研究得出滑动构造是正断层演化的结果,属于正断层的一种类型的新认识。认知滑动构造的意义在于:可在较新地层下寻找、预测埋藏较浅的煤层,如芦店滑动构造区。若按传统构造解释,芦店地区地表出露为中生界三叠系红层,其下伏主采二1煤埋深一般在1 400m左右,超过现行勘查规范资源储量估算垂深1 200m以浅的要求,但利用滑动构造观点客观、合理解释后,煤层埋藏深度最浅处只有几十m。芦店滑动构造的解释成为利用新理论找煤的一个典型范例。
The Ludian gliding tectonics is a typical model in gliding tectonics group in the Songshan-Jishan area, western Henan Province. Its main manifestations have superimposition of two stage gliding movements in opposite directions, matching of two kinds of gliding structural models and actions of two dynamic factors. Through comprehensive research has worked out a new understanding of the gliding tectonics that it is a result of normal fault evolution, one kind of normal fault. The significance to understand gliding tectonics is rested with： can seek coal seams under newer strata and predicted buried depth could be shallower, such as in Ludian gliding tectonics area, according to the traditional interpretation, on the surface, Mesozoic Triassic red beds outcropped, underlying No.Ill coal seam buried depth should be about 1400m, thus beyond the requirement of 1200m of active resource exploration criterion reserve estimation vertical depth. If objectively and rationally interpreted by the use of gliding tectonics point of view, the shallowest buried depth can be only tens of meters. Thus the interpretation of Ludian gliding tectonics has resolved into a typical model of coal looking through new theory.
