Трофометаболическая активность дождевых червей (Lumbricidae) как зоогенный фактор поддержания устойчивости рекультивированных почв к загрязнению медью

Рассматриваются вопросы зоогенного формирования защитных возможностей почвы к действию повышенного содержания тяжелых металлов в условиях техногенеза. Исследованы особенности трофометаболической активности дождевых червей на участке лесной рекультивации Западного Донбасса с различными вариантами насыпных почвогрунтов. Доказано, что копролиты червей активно влияют на иммобилизационную способность почвогрунтов (в частности, на буферность к тяжелым металлам на примере меди), которая увеличивается для копролитов в ряду «безгумусный лессовидный суглинок – верхний гумусированный слой чернозема обыкновенного». Эффективность иммобилизации меди копролитами дождевых червей на участке с насыпкой из чернозема статистически достоверно больше, чем эффективность иммобилизации исходного почвогрунта. Проведенные исследования позволяют рассматривать трофометаболическую активность дождевых червей как зоогенный фактор, важный для ограничения движения избыточного количества химических элементов, поддержания устойчивости и повышения защитных свойств почвогрунтов к загрязнению медью. При этом возможно ускорение натурализации искусственного лесного эдафотопа на рекультивированных землях и возрастание его экологической ценности.

Ecological safety of subterranean water on the territory of mining enterprises

Specific features and sources involved in forming the modern ecological state of subterranean water in Western Donbas at the location zone of filtering gathering ponds of mining water have been estimated. Mechanisms of the metamorphization and the level of ecological safety of subterranean water at different aquifers were determined. The priority toxicant components were separated, and the developed pollution areas of subterranean water were identified that require the monitoring and prediction of their ecological state.

Usage of Cable Bolts for Gateroad Maintenance in Soft Rocks

This paper analyses the effectiveness of gateroad reinforcing by means of cable bolts under weak rock conditions. In the worldwide mining industry the method of gateroad support reinforcement using cable bolts is considered to be effective. The experimental application of cable bolts was performed in gateroad #165 of the "Stepova" mine, Western Donbass, Ukraine, and required instrumental control of "support-rock mass" system conditions. Obtaining absolute displacement of "support-rock mass" system elements and extensometer anchors by means of levelling in order to improve the method of observation. The peculiarities of geomechanical behaviour of rock mass in the roof of gateroads is investigated. It has been established that the application of cable bolts allows for a reduction in the vertical convergence of the gateroad, both in front of and behind the longwall face. Advantages of cable bolts instead of end-face support and props in case of a high advance rate of the longwall face are shown. 1. There are no regulations and state standards in regard to cable bolt installation parameters in the mines of Ukraine, consequently the usage of cable bolts for gateroad maintenance required preliminary testing under geological conditions at the Western Donbass mines with soft enclosing rocks. 2. Combining levelling with observations using extensometers allowed for the detection of the rock layers' uniform sagging zone in the roof of the gateroad.

Basin evolution and coal geology of the Donets Basin (Ukraine, Russia): An overview

Abstract The Donets Basin is a major coal-mining district in eastern Ukraine and adjacent portions of Russia. It comprises the Donbas Foldbelt, which is the uplifted and compressionally deformed part of the Pripyat–Dniepr–Donets (PDD) Basin, and the significantly less deformed Western Donbas region. The PDD Basin is a Late Devonian rift structure located within the East European Craton. Thick coal-measures formed during the post-rift stage of the basin in Serpukhovian to Moscovian times, when about 130 seams, each with a thickness over 0.45 m, have been deposited. Early Serpukhovian coal accumulated in a relatively narrow shore-zone. It is rich in inertinite and liptinite and very low in ash. Bashkirian and Moscovian coal have a significantly wider lateral extension and are generally rich in vitrinite. Bashkirian and Moscovian coal seams usually have high ash yields (12–18%) and high sulfur contents (2.5–3.5%), but these data vary significantly depending on peat facies. Coal rank ranges from subbituminous to anthracite and is mainly controlled by the depth of the seams and the heat flow during maximum (Permian) burial. Permo-Triassic thermal events locally overprinted the resulting coalification pattern. Coked coal occurs at the contact to presumed Permian sills and dikes southwest of Donetsk. Deep Permian burial was followed by major Permian and Mesozoic uplift events. The Donets Basin hosts proven reserves in the order of 60 Gt at the exploitable depth. The thickness of coal seams currently mined is in the range of 0.6 to 2.5 m. Production during 2009 was 68.7 Mt in the Ukrainian and 4.9 Mt in the Russian part of the basin. Coal mines in the Donets Basin are among the gassiest in the world. The average methane content of coal is 14.7 m³/t, but numerous seams have significantly higher gas content. The high methane content presents a severe mine safety problem. On the other hand, it represents also a high potential for coal mine bed methane projects. Emissions of coal gas released by mining and related structurally induced underground hazards (coal and gas outbursts) are a major problem for safe and efficient coal exploitation in the basin.

Analysis of primary productivity of robinia pseudoacacia plantations on reclaimed lands of steppe Pridneprovye

Pattern of phytomass spatial distribution and interrelation between spreading 15 and 17-years-old robinia plantings and forest-vegetable conditions created on the revegetated areas of Western Donbas are analyzed in the present article. Primary productivity depends on thickness and fertility of used substrates, relief and landing density.

Petrographic structure and composition of the Lower Carboniferous coal seams, western Donbas; their influence on chemical and technological properties of coals

The Lower Carboniferous coals which have been discovered and explored in the western Donbas since the war differ from those in the productive series of the old Donbas in age, petrographic composition and chemotechnological properties. From the Orel' river in the west to me Kal'mius river M the east the following have been recognized in the Lower Carboniferous: Visean coals of the sub-coal measures suite C2 1(b), Visean coals of the Samarsk suite C3 1 (c), and Namurian coals of suites C4 1 and C5 1 (d and c). The Lower Carboniferous coals over most of the western Donbas have (for a given rank) a higher yield of volatiles and primary tar, heat of combustion, sintering capacity, and hydrogen content. The rank increases to the northeast and produces a zonal disposition of coals of industrial type. The degree of coalification also increases with burial of the seams in the southwest limb of the Dneprovsk-Donets basin at depth. The basic aspect of metarnorphisrn is regional.'
