通过分析显微图像的光学性质和测定煤的反射率等方法,研究了新疆中生代煤中半镜质组特征。结果表明:新疆中生代煤中含有一定量的半镜质组;均质半镜质体占总体(均质镜质体与均质半镜质体之和)的49%~64%,均质半镜质体的最大反射率(Rmax)比均质镜质体的高0.08%~0.13%;均质半镜质体的Rmax介于均质镜质体和结构镜质体之间,结构半镜质体的Rmax比结构镜质体的高0.28%~0.34%。由此可以得出:在三大组分划分方案中,应将均质半镜质体归入镜质组的均质体中,同时认为,按显微组分三大组分划分方案中,将结构半镜质体归入惰质组的半丝质体中更合理;在测定煤的反射率时,不能将均质半镜质体作为反射率的测定对象。本项研究结果对于指导本地区煤炭的炼焦配煤、煤炭液化和深加工利用等具有重要意义。
通過分析顯微圖像的光學性質和測定煤的反射率等方法,研究瞭新疆中生代煤中半鏡質組特徵。結果錶明:新疆中生代煤中含有一定量的半鏡質組;均質半鏡質體佔總體(均質鏡質體與均質半鏡質體之和)的49%~64%,均質半鏡質體的最大反射率(Rmax)比均質鏡質體的高0.08%~0.13%;均質半鏡質體的Rmax介于均質鏡質體和結構鏡質體之間,結構半鏡質體的Rmax比結構鏡質體的高0.28%~0.34%。由此可以得齣:在三大組分劃分方案中,應將均質半鏡質體歸入鏡質組的均質體中,同時認為,按顯微組分三大組分劃分方案中,將結構半鏡質體歸入惰質組的半絲質體中更閤理;在測定煤的反射率時,不能將均質半鏡質體作為反射率的測定對象。本項研究結果對于指導本地區煤炭的煉焦配煤、煤炭液化和深加工利用等具有重要意義。

Through the analysis of the optical properties of maceral images and determining microscopically the reflectance of the coal macerals, the characteristics of the semi-vitrinite group of Mesozoic coal in Xinjiang are studied. The analysis results show that there exist certain amount of semi-vitrinite group in the Mesozoic coal in the region. The content of semi-telocollinite is 49%~64% of the total amount of telocollinite and semi-telocollinite. The maximum reflectance of semi-telocollinite is 0.08%~0.13% higher than that of the telocollinite. The reflectance of semi-telocollinite is between that of the telocollinite and telinite. The reflectance of the semi-telinite is 0.28%~0.34% higher than that of telinite. From the above-mentioned results, it can be concluded that semi-telocollinite should be classified as vitrinite and it is reasonable that the semi-telinite is classified as semi-fusinite in inertinite. It is important that the semi telocollinite should not be measured as the object while determining microscopically the reflectance of vitrinite in coal. So the study is very useful for coal blending of coking coal, coal liquefaction and further coal processing and utilization.
