Study on the Relationship between The diversity Coal mass structure and Lithotype of coal In multi-coal Seam mine

摘要

Through site observation and indoor measurements in Xie Jiaji No.2 Coal Mine in Huainan and luling coal mine I Huaibei, it is discovered that the fragmentation degree are dif- Ferent in different coal seams in same mining district and even in sublevels of the same coal seam, The coal mass structures exist much difference. By analyzing the relationship between the onsti- Tution of coal matters and the epigenesis breakage of coal. This paper points out that the internal Factor which causes the diversity of the coal mass structure comes from the diversity in the con- tents of telocollinite and desmocollinite in the vitrinite.
