“特殊”煤光片制备及对煤岩分析的主要影响
|
摘要
煤岩分析在煤相研究、地质勘查、炼焦配煤等诸多方面有广泛应用;合格的煤光片是煤岩分析的前提。为解决易碎裂样品、老化煤光片等"特殊"煤光片的制备问题,提出了一套完整的制备流程,并实际验证了流程的可行性。老化粉煤光片二次煤岩分析结果表明:镜质体反射率受二次制备影响极小,显微组分含量受二次制备影响显著,且无烟煤的显微组分含量波动最大。老化粉煤光片二次显微组分定量时,应注意区分无烟煤的镜质组和惰质组,适当增加烟煤光片检测点数,以减小煤的非均质性对结果的影响。
Coal petrology analysis is widely used in coal facies research, geological exploration and coal blending test. Qualified polished coal slice is the premise of coal petrology analysis. In order to solve the preparation problem of special coal optical plates, such as brittle samples and aging coal optical plates, a complete preparation process was raised, and the feasibility of the process was verified. The results showed that Rmax was very little affected by secondary preparation, but the maceral group composition content was significantly affected, and the fluctuation of the anthracite' microcomponent was the greatest. When the maceral group composition quantification of the aged special coal polished slice, attention should be paid to distinguishing between the vitrinite and intertinite of anthracite, and to increasing the test number of the bituminous coal' optical plates, to reduce the effect of the coal' heterogeneity on the results.
