Characteristics and Sedimentary Environment Analysis of Coal-bearing Stratum in Hongshaliangdong Minefield
Through the study of the distribution of Laoshuwo group coal-bearing stratum of Lower Cretaceous in Hongshaliangdong minefield,combined with the comprehensive analysis of regional structure and sedimentary environment,the results showed that the coal-bearing stratum reveals a small coal basin.The coal-bearing property of central and western area is good,however,become worse gradually around.The sedimentary environment mainly included fan delta,lake and lake delta.Thedelta plain bogs and lakefront bogs developed during this period were the main sites for coal formation,during which formed four minable seams.
