| Abstract: | In this paper, the macroelement of workable coal of Mukong coal mine is analysed, sulfur, c/s value and grey are used as reference index, the sedimentary environment of workable coal is discussed. The coal No.2, 3 and 4 formed in delta peat swamp where has rich continental material supply, low salinity and weak reduction. Coal seam No.5 and 7 formed in lagoon facies peat swamp with medium salinity and weak re- duction which is effected by sea water. |
