Coal-bearing characteristics and coal -searching prospect of Ceshui Formation in Shengli-Lijiawan coal mining area of Hunan province

On the basis of collecting data of regional geology, mineral resources, geophysical exploration and researches related to Meicheng-Hanpo depression, through combination of technical approaches such as measured geological sections, geological mapping, trenches, record of active mines, electrical exploration, sampling and laboratory analysis, by using comparison of geological conditions and analogizing the coal-bearing properties, the characteristics of the coal-bearing series of Ceshui Formation in Shengli-Lijianwan Mining area were assessed comprehensively to search coal-rich zone and thick coal in old mining area of Lianyuan coal-bearing region.Three prospective areas(Hejiawan-Zhoujiawan-Youxi, Jietouling-Lianfeng-Caishanchong and Baijialin) were delineated as key survey targets for coal-searching.
