Analysis of Environmental Characteristics of Continental Coal Formation in Guizhou Province
In order to objectively reflect the basic geological characteristics of typical ore deposits in the continental coal-forming environment of Guizhou province to the maximum extent,the sampling posi-tions and quantities of Meitan'gou Coal Mine and LUOZHOU Coal Mine are reasonably determined on the basis of collecting the previous geological exploration data and the current situation of field exploration,and the coal rock samples are analyed.The results show that the samples from the two coal mines are well consol-idated and can represent the environmental characteristics of continental coal formation and have corre-sponding coal characteristics.At the same time,through field investigation,Kele Township of Hezhang County was selected as the measured section location to collect and preserve the representative rocks,coal,fossil specimens and borehole samples of different specifications in the coal-bearing rock strata.The results show that the Xuanwei Formation is mainly composed of gray fine sandstone,siltstone,silty mudstone,ar-gillaceous siltstone,clay rock and coal seam,which clearly reflects the sedimentary environment character-istics of the coal-bearing formation Xuanwei Formation(P3x),and is a set of coal-bearing sedimentary for-mation in continental strata.
