摘要

目的。建立了卡尔米乌斯区块C12组煤层的岩石学和化学工艺特征。方法。采用一般的科学和应用研究方法来完成任务。借助岩石学方法,详细研究了煤的宏观和微观组成特征,确定了煤的回收和变质程度。借助化学和工艺方法,对煤的组成和质量进行了全面的描述。利用现代的分析和解释方法,可以提供煤层的一般特征,揭示其组成和质量的特点。发现。首次揭示了下顿巴斯C12煤系组成和质量的区域(“省”)特征。它们的典型岩石组成是在卡尔米乌斯方块上确定的。确定了C12组煤与C13组煤在大体岩相组成和显微成分上的差异。此外,它们还具有不同程度的恢复的特点。在地层剖面上,从下世界各层到上世界各层,惰质组和脂质组的显微组数量增加,镜质组数量减少。确定了煤的成分和质量变化的横向规律。结果表明,与C13煤系相比,C12煤系的硫含量、燃烧热、塑性层厚度和Rog指数具有较高的特征。C12煤层组的元素组成具有碳、氢含量高、氧含量明显低的特点。揭示了下石炭统煤岩相组成的变化。的创意。首次建立了顿巴斯南部下石炭统地层剖面典型煤岩组成的变化,表明泥炭地形成的不同条件。实际的实现。明确了该地区煤炭的区域(“省”)特征,确定了其组成和质量指标的横向和地层变化,根据乌克兰现行新标准建立了煤的品位组成,并计算了C12地层煤的技术价值。

Petrographic and chemical-technological characteristics coal seamsof the lower carbon,formation C12 of the kalmiusblock
Purpose. To establish the petrographic and chemical-technological features of the coal seams of formation C12 of the Kalmius block. Method. General scientific and applied research methods were used to fulfill the tasks. With the help of petrographic methods, the macroscopic and microscopic characteristics of the composition of coal were studied in detail, and the degree of its recovery and metamorphism was determined. With the help of chemical and technological methods, a comprehensive description of the composition and quality of coal is provided. The use of modern methods of analysis and interpretation made it possible to provide a generalized characteristic of coal seams, to reveal the peculiarities of their composition and quality. Findings. For the first time, regional ("provincial") features of the composition and quality of the coal formation C12 for Lower Donbass were revealed. Their typical petrographic composition was determined on the Kalmius block square. It was established that the coal of formation C12 differs from coal of formation C13 both in terms of gross petrographic composition and maceral composition. In addition, they are characterized by different degrees of recovery. It is proved that in the stratigraphic section, from the layers of the lower world to the layers of the upper world, the number of maceral groups of inertinite and liptinite increases, and the groups of vitrinite decrease. Lateral regularities of changes in the composition and quality of coal are determined. It was established that, compared to coal formation C13, higher values of sulfur content, heat of combustion, thickness of the plastic layer, and the Rog index are characteristic of coal formation C12. The elemental composition of the coal seams formation C12 is characterized by higher values of carbon and hydrogen content and significantly lower values of the amount of oxygen. Changes in the petrographic composition of Lower Carboniferous coal were revealed. The originality. For the first time, changes in the typical petrographic composition of coal in the Lower Carboniferous stratigraphic section of Southern Donbas, which indicate different conditions of formation of peatlands, were established. Practical implementation. The regional ("provincial") features of the region's coal have been clarified, lateral and stratigraphic changes in its composition and quality indicators have been determined, the grade composition of coal according to the new current standard in Ukraine has been established, and the technological value of formation C12 coal has been calculated.
