Geological characteristics of coal and graphite in Hanpoao mining area in northern section of Lianshao coalfield of Hunan Province

In order to determine the influence of the granitic rocks on coal graphitizing, to exploit mineral resources rationally, and to guide the prospecting work of the same kind of coal and graphite, we did sampling and testing, analyzed characteristics and distribution range of coal and graphite ore in Hanpoao mining area, summarized the metallogenic model of graphitizing in coal-bearing strata, determined that within 500~600 meters from the rock mass, the degree of coal graphitizing was high. It was predicted that there is a big potential to search for large-scale graphite ore in the sourth of Hanpoao mining area.
