Study on Sequence Stratigraphy and Analysis of Ore-Controlling Factors and Coal Prospecting Potential of Badaowan Formation in Wucaiwan mining area,Zhundong Coalfield
Sedimentology and sequence stratigraphy of badaowan Formation in Wucaiwan mining area of Zhundong coalfield,are analyzed by using the methods of coal geology and sequence stratigraphy,and the distribution characteris-tics of coalbed under the sequence stratigraphy framework are discussed,the main controlling factors of coalbed accumu-lation are analyzed,and the law of coalbed accumulation is preliminarily summarized.The results show that the coal seams of badaowan Formation are mainly developed in the coastal and shallow lake area during the sedimentary period of the two-stage lake expansion system tract,and the coastal and shallow lake in the inner lake expansion system tract still spread to the west,south and east of the area.Therefore,there is a potential for further coal exploration in the west,south and east of the area.
