地质构造对宿南矿区72煤层厚度变化的控制作用
Controlling effect of geological structure on the thickness variation of 72 coal seam in Sunan mining area
摘要
Abstract
Sunan mining area plays an important role in Huaibei coalfield and coal seam 72 is one of the minable coal seams in the mining area. Geological exploration data show that the change of coal seam is large and it’s thickness variation is obvious. Based on the research of mine geological survey and geological structure, it is found that the coal structure is broken, and the thickness variation of coal seam is closely related to the geological struc-ture in the area. The distribution of coal thickness shows NW-SE alternative thickening and thining, the direction is the same as the overall fold direction. The local thickness variation is closely related to the trend of the fault strike and the axial direction of the fold. Therefore, excluding the impact of the coal seam of primary sedimentary factors, the faults, the folds and the layer slip structure associated with fold action mainly control the thickness variation of coal seam.关键词
