摘要

目的。探讨顿巴斯北部成碳期大地构造制度对煤层物性发育的影响。方法。为了完成既定的任务,使用了许多研究方法,包括岩石学、化学和技术、相和构造、计算、统计和分析、信息、年代、遗传、比较和其他方法。发现。确定了大地构造制度对煤质形成的影响。证明了微元群数目的变化具有规律性。岩石和岩石的显微群数量的减少,与显微风群数量的增加相对应,是在碳形成积累过程中地壳振荡运动的总振幅和平均速度的增长方向上发生的。创意。从统一的地球动力学角度来看,煤的形成被认为是伴随着岩石圈深部构造(板块)的发展和相互作用的一系列复杂自然过程的组成部分。重点讨论了在岩石圈运动性质不同的地球动力条件下形成的煤的组成和质量的特殊性。首次对老顿巴斯与北顿巴斯中石炭世含煤地层进行了对比分析。给出了顿巴斯北部煤层的详细岩石学和化学技术特征。与中石炭统其他地层的煤相比较,首次确定了三角洲-沼泽-海相组煤的组成和质量特点。实用价值。已经确定了顿巴斯北部地区三角洲-沼泽-海洋和冲积-沼泽-海洋地层的煤组成和质量的区域(“省”)特点,这将使其合理使用的方向得到证实。提出的方法使预测烟煤分布区的含煤量以及煤的组成和质量成为可能。将顿巴斯北部的煤炭加入乌克兰燃料基地的方便性和前景得到了证实。

Influence of the geotectonic regime on property formation of coal in the northern edges of the Donetsk basin
Purpose. To determine the influence of the geotectonic regime during accumulation of carbon formation on development of coal-bed properties of the northern Donbas. Methodology. To perform the tasks set, a number of research methods were used which include petrographic, chemical and technological, facies and tectonic, computational, statistical and analytical, informational, chronological, genetic, comparative and other methods. Findings. The effect of the geotectonic regime on the formation of coal properties has been established. It is proved that the change in the number of maceral groups is of a regular nature. The reduction in the number of maceral groups of liptinith and irtinitis, in the light of the increase in the number of maceral wind group, is taking place in the direction of the growth of the total amplitude and average speed of the oscillating movements of the Earth’s crust during the accumulation of carbon formation. Originality. Coal formation is considered regarding a unified geodynamic perspective as an integral part of a complex set of natural processes that accompanied the development and interaction of deep structures (plates) of the lithosphere. The main attention is paid to the peculiarities of the composition and quality of coal formed under geodynamic conditions with different motion nature of the lithosphere. For the first time, comparative analysis of the coal-bearing formation of the middle Carboniferous period of the Old and Northern Donbas has been performed. Detailed petrographic and chemical-technological characteristics are given to the coal seams of the Northern Donbas. The peculiarities of the composition and quality of the coal of the deltaic-bog-marine formation have been determined for the first time compared to the coal of other formations of the Middle Carboniferous. Practical value. Regional (“provincial”) peculiarities of coal composition and quality of deltaic-bog-marine and alluvial-bog- marine formations of northern Donbas regions have been defined, which will allow substantiating the directions of its rational use. The proposed approach makes it possible to predict coal content as well as composition and quality of coal in the areas of distribution of bituminous coal. The expediency and prospects of adding the coal of northern Donbas to the fuel base of Ukraine are proven.
