Abstract:Tengdong exploration area is located in the south of Tengzhou city. Tengdong coal mine is in the west with a low exploration degree. 33 two-dimensional seismic survey lines have been constructed. The length of the survey lines is 59.65km, and there are 158 physical points. 26 boreholes (including 4 hydrological holes and 1 coalbed methane parameter hole) have been completed, and the construction quantity is 27753.63m. Geophysical logging of 26 holes have been completed with an engineering quantity of 27479.51m. It has been identified that the coal-bearing strata in the exploration area are Taiyuan formation and Shanxi formation. Its structural types are moderate, and wide and gentle folds and magmatic rocks have developed well. The hydrological, engineering, and environmental geological conditions are all of medium type. It has been discovered that coal strata of the lower part of No.3 layer is a relatively stable coal seam that can be mined in the entire area, and No.16 coal seam is a relatively stable coal seam that can be mined in most parts. A total of 7105.9 ten thousands tons of coal resources have been identified within the depth of -1200m.
