宁夏汝箕沟矿区大峰井田侏罗纪煤层煤岩学特征

The Jurassic coal petrology characteristics of Dafeng mine field in Rujigou Coal Mine, Ningxia

通过野外勘探、煤田钻探等资料,结合室内外试验,探讨了汝箕沟矿区大峰井田侏罗纪煤层地质特征、煤质特征及煤岩成因。结果表明,该煤层地质构造简单,发育稳定,煤质较好,以低灰、低硫、低磷的优质煤为主,显微煤岩组分以镜质组为主。该研究为今后寻找品质优良的煤炭资源,更加高效、合理、洁净开发利用煤炭资源提供了参考依据。

According to the data collected from field exploration, coalfield drilling, field investigation and laboratory experiment,the characteristics are emphasized on geological, coal quality and its causes in Jurassic coal at Dafeng mine field in Rujigou Coal Mine, Ningxia. The results show that the geological structure of the coal seam is simple and development is stable,the quality of coal is good, for it has features with low content of ash, sulfur, phosphorus. The study provides references to find good coal resources, references to develop and utilize more efficiently, reasonably and cleanly.
