摘要

目的。这项工作的目的是建立和分析顿巴斯Pavlohrad-Petropavlivka地区“Ternivska”矿区c522煤层中锗浓度、有毒元素和总硫含量之间的关系。方法。这项工作的事实依据是对煤层中锗、铍、氟、汞、砷和总硫的分析结果。采用定量发射光谱法测定Ge、Be、F的含量,采用原子吸收法测定Hg、As的含量。使用STATISTICA 13.3和IBM SPSS Statistics 22程序计算主要描述性统计指标的数值。利用Micromine程序实现的方法进行相关分析和回归分析,并在地质概念中进行分析。结果。证实了捷尔涅夫斯卡矿c526煤层中As、Hg、Ge和总硫的最低含量是在其形成的同生阶段共同积累的。Ge和Be在低浓度和异常低浓度区域含量的同时增加是由于这两种元素在煤层形成同生阶段的联合富集造成的,它们在最大含量区域的增加是由于“Zilbermints定律”的经验规律的表现。证明了捷尔涅夫斯卡煤矿c522煤层中Ge含量、有毒元素和总硫含量的分布不同于高斯-拉普拉斯分布和对数正态分布,分布的多模态是固定的,分布密度核向左偏移。所进行的研究结果的科学新颖性在于确定所有考虑元素的样本不符合正态或对数正态分布规律,而在所有情况下都记录了指标分布的多态,这是通过使用Kolmogorov-Smirnov, Shapiro-Uilk标准对高斯分布的研究参数的经验分布的对应性的分析计算来证实的。Lilliefors和Pearson的卡方一致。结果表明,所研究元素在克拉克附近浓度的煤和在含量增加的煤中的发现形式有显著差异。揭示了同生和表观生过程对捷尔涅夫斯卡煤矿c526煤层中Ge浓度、有毒元素与总硫含量关系性质的影响。研究结果的实际意义在于确定了锗和有毒元素浓度与总硫之间存在极低的相关性,因此,从煤层中提取锗在工艺过程中不会伴随锗的大量积累。事实证明,为了更真实地评价锗、有毒元素含量和总硫含量的集中趋势,有必要使用中位数而不是算术平均值。关键词:锗、铍、汞、砷、总硫、煤层、频率直方图、回归分析、相关分析、分布多态

RELATIONSHIP FEATURES OF GERMANIUM CONCENTRATIONS WITH THE CONTENT OF TOXIC ELEMENTS AND TOTAL SULFUR IN COAL SEAM C5B OF THE «TERNIVSKA» MINE
Purpose. The purpose of the work is to establish and analyze the relationship between germanium concentrations, toxic elements and the content of total sulfur in the coal seam c5в of the «Ternivska» mine field of the Pavlohrad-Petropavlivka area of Donbas. Methodology. The factual basis of the work was the results of germanium, beryllium, fluorine, mercury, arsenic and total sulfur analyzes in the coal seam c5в. The content of Ge, Be, and F was determined by quantitative emission spectral analysis, Hg and As by atomic absorption analysis. Using the STATISTICA 13.3 and IBM SPSS Statistics 22 programs, the values of the main descriptive statistical indicators were calculated. Correlation and regression analysis was carried out using the methods implemented in Micromine program and their analysis was carried out in geological concepts. Results. It is substantiated that the minimum contents of at least As, Hg, Ge and total sulfur in the coal seam c5в of the "Ternivska" mine were jointly accumulated at the syngenetic stage of its formation. The simultaneous increase in the content of Ge and Be in the area of their low and abnormally low concentrations is caused by the joint accumulation of these elements at the syngenetic stage of coal seam formation and their increase in the area of maximum contents is caused by the manifestation of the empirical regularity of the «Zilbermints law». It is proved that the distribution of the values of Ge content, toxic elements and total sulfur in the coal seam c5в of the «Ternivska» mine differ from the Gaussian-Laplace and lognormal distributions, in all cases the polymodality of the distribution is fixed and the kernel of the distribution density is shifted to the left. Scientific novelty of the results of the conducted research consists in establishing the non-compliance of the samples of all considered elements with the normal or lognormal distribution law, while in all cases the polymodality of the distribution of indicators is recorded, which is confirmed by analytical calculations of the correspondence of the empirical distributions of the studied parameters of the Gaussian distribution using the Kolmogorov-Smirnov, Shapiro-Uilk criteria, Lilliefors and Pearson's chi-squared agreement. It is proved that the forms of finding of the investigated elements in coal with their concentrations around Clark and in coal with increased contents differ significantly. The influence of syngenetic and epigenetic processes on the nature of the relationship between Ge concentrations, toxic elements and the content of total sulfur in the coal seam c5в of the «Ternivska» mine was revealed. Practical significance of the results of the work consists in establishing the presence of a very low correlation between the concentrations of Ge and toxic elements and total sulfur, therefore, the extraction of germanium from the coal seam will not be accompanied by their significant accumulation during technological processes. It has been proven that for a more realistic assessment of the central tendency of the content of Ge and toxic elements and total sulfur, instead of the values of the arithmetic mean, it is necessary to use the median values. Key words: germanium, beryllium, mercury, arsenic, total sulfur, coal seam, frequency histograms, regression analysis, correlation analysis, polymodality of distribution.
