韦五井田断层发育特征及其对煤层赋存的影响作用分析

Function analysis of development characteristics of Wei five field fault and its influence on coal seam

韦五井田处于韦州向斜西翼北端,断层较为发育,以北北西向逆断层为主,东南部见有小规模近东西向、北东向及近北西向断层。北北西向断层落差普遍较大、延展较长,控制含煤地层的展布,导致局部地层重复或缺失。断层特点及分布情况显示本区主要遭受东西向构造应力挤压而形成近南北向的狭长断块,由西向东逆冲。

Wei wu mine ifeld located in the state of the northern end of the west limb of Weizhou syncline, which faults were developed, NNW reverse faulting is given priority to, has a small scale near east-west, North East and near NW trending faults in southeastern. The NNW fault fall is generally big, long extension, which control the distribution of the coal bearing strata, and lead to local duplication or deletion. The fault characteristic and distribution showed the area mainly things to display suffered the tectonic stress extrusion to form nearly north-south strip of fault block, and thrust from west to East.
