摘要
就阳煤集团公司新景矿不协调褶皱、挠曲的空间分布规律进行了研究,得出挠曲构造呈NNE—NE向斜列,在下部煤组密集、上部煤组少,且为断层所代替,纵向上延伸不太远。这种结果是由软硬相同的岩层组合在构造应力作用下形成的。利用褶曲、挠曲的分布规律预测其在上下煤组中出现的可能性,可以大大节约时间和经费,提高生产效率。
This paper studies space distribution rule with irregular wrinkles and deflections in Xinjin Coal Mine of Yangquan group,deflection struction is NNE-NE,the lower coal seam groups are concentrated,uppers are sparsed.This is because of formed by soft-hard rockstrata combined under tectonic stress action.Upper-lower coal seam groups are forcased by wrinkles and deflections rule time and funds are saved sfficiency of production is raised.
