Purpose. Determination of ecological patterns for vegetation cover formation in the mining waste dumps of the Lviv-Volyn coal basin based on the ecotopes floristic composition analysis of waste heaps reclaimed and non-reclaimed. Methods. The phytoindication of ecological regimes is used based on the ecological parameters of herbaceous species of vegetation covering the mining waste dumps; data retrieval techniques (Data Mining methods); plant species multivariate ordination based on the main components analysis (Principle Component Analysis); statistical processing of ecotopes ecological parameters of the mining waste dumps. Findings. A phytoindication assessment has been performed of the conditions in the places of growing 8 ecological-cenotic groups and 5 subgroups of plant species representing various ecotopes of reclaimed and non-reclaimed waste dumps of mines according to nine parameters: Tmthermal regime, Knclimate continentality, Omombroclimate, Crcryoclimate, Hdsoil moisture, Trsalt content, Rcsoil acidity, Ntmineral nitrogen, Lcluminosity-shadowing regime. It has been found that with decreasing parameters of climate humidity, shadowing in cenosis and soil moisture, the indexes of thermal regime, continentality, soil pH and salt content increase. It is recommended to present the typological scheme of the vegetation covering the mining waste dumps in the form of a quadrangle, in the centre of which meadow and synanthropic vegetation is located, and in the cornersboreal and psammophilous vegetation; nemoral-forest; hydrophilous; meadowsteppe and calcetrophilic. Originality. It has been revealed that the vegetation covering the mining waste dumps of the Lviv-Volyn coal basin is characterized by an ecological-cenotic areal. It has been assessed on the basis of the species ordination on the axes of complex environmental gradients, and the center of this areal is occupied by meadow and synanthropic species, which demonstrate greatest sustainability under the conditions of mining waste dumps. The most vulnerable species are meadow-steppe, calciphilous, hydrophilous vegetation, the ecological-cenotic areal of which is characterized by the location on the periphery of the general vegetation areal of mining waste dumps. Practical implications. The ecological parameters of flora species make it possible to determine their position in the ecological-cenotic areal of vegetation covering the mining waste dumps of the Lviv-Volyn coal basin, as well as to predict their sustainability and dynamics.

“…Therefore, there are increasing numbers of studies highlighting the succession of post-industrial habitats, including in the context of restoration ecology and conservation biology (Harabis, Tichanek, & Tropek, 2013;Lundholm & Richardson, 2010;Walker & Moral, 2003). The most common studies focusing on organisms colonizing such places relate to vegetation (Ash et al, 1994;Kovar, 2004;Prach et al, 2013;Song, Shu, Wang, & Liu, 2014). There are several papers focusing on primary succession of arthropods in post-industrial habitats, however, they focus mainly on specific topics e.g.…”

Purpose. Investigation of the choice of parameters of equipment for extinguishing coal mining wastes that go to the formation of waste dumps, the choice of the main components of equipment for the operation of technological units and a schematic diagram of equipment for extinguishing coal mining wastes are proposed. Methods. Analysis of existing approaches to technological solutions to prevent combustion of waste dumps; environmental assessment of alternative options for technological solutions to prevent combustion of waste dumps; creation of an environmentally friendly design technology for the use of coal mining waste. Results. Based on in-depth analysis of the main components of technological units for the operation of the equipment, MFP FullJet irrigation nozzles by Spraying Systems Co. were proposed. – USA, their main advantages are considered. The expediency of using a hydraulic network, which includes pipelines made of polypropylene material produced by “Aquatherm” – Germany, are substantiated; the main component of the pipelines is the material “Fusiolen”, the advantages of which are given in the article. An integral part is pumping equipment, consisting of centrifugal pumps for water supply (1VNS 60-66) and (VNSp 2.5) for supplying limestone suspension to irrigation nozzles of the transporting dump mass. Scientific novelty. Equipment for extinguishing coal mining waste (rock dumps) resistant to spontaneous combustion is proposed, in which the introduction of new structural elements and their interconnection is achieved by the continuous control and management of spraying per unit of the transported surface of the dump rock, dispersed with an inert substance (lime suspension), which prevents the formation of active combustion centers during the operation of waste heaps. Timely coverage of the dump mass with an inert substance reduces the time of contact of the rock with the environment, which is an important stage in the formation of rock dumps, especially of a conical shape, reduces the cost of operation and maintenance due to the formation of fire-resistant dumps, regardless of the influence of environmental conditions. Practical implication. Efficiency from the use of equipment for extinguishing coal waste can be obtained due to the continuous work achieved by covering the dump mass with an inert mixture during transportation, this reduces the contact of the rock with the environment, which is an important stage in the formation of rock dumps of a particularly conical shape, and reduces operating costs and their maintenance due to the formation of fire-resistant waste dumps regardless of the influence of environmental conditions.
