Human needs for resources are growing every year. Waste recycling and alternative sources of electricity will not be able to meet the growing needs of mankind. The number of useful resources on our planet, unfortunately, is limited [1, 2].

Purpose. Using the special pneumopercussion machines it is improving the efficiency of the process of the thermodynamic processes in the working chambers. Methodology. The studies were carried on thermodynamic processes of compressed air work in the working chambers of pneumopercussion machines for the increasing their efficiency.

Purpose. Using the special methods of processing it is proposed the forming of copper concentrate for further industrial usage. Methodology. The studies were carried on using continuous smelting of copper concentrates for the production of copper from sulfide concentrates by pyrometallurgical method.

Substantiation of new methods and technologies of processing and enrichment of technogenic wastes and previously formed wastes of mining and metallurgical production [1-5]. The choice of areas of rational use of man-made waste from mining and metallurgical production must be performed on the basis of a comprehensive study of raw materials, as well as the analysis of potential consumers in the region of the producer.

Purpose. Identifying the causes of additional energy consumption for deformation of the drill string. Methodology. The study was conducted by analyzing the causes of deformations and justifying their impact on the dynamic parameters of the drill string.

Study of the mineralogical and chemical composition of waste rocks from the Western Donbass coal mines dumps to establish the presence of valuable components and their subsequent industrial development. The present work is a continuation of work [1-3]. This work expands the knowledge about the availability of valuable components in waste dumps for industrial development of their resources in the future [4-12].

Purpose. Study the impact of the peculiarities of international and national legislation in the field of colored gems mining on the success of the world's leading companies in order to activate the gemstone market in Ukraine. Methodology.Researches were performed by analyzing information from open sources, both scientific publications and annual reports of companies.

Purpose. Study of the spatial distribution of manganese in the coal seam c 5 of the “Blagodatna” mine field and the establishment of relationship between its content and the main technological parameters of coal in the region. Methodology. For the purpose of determine the composition of geochemical associations, correlation coefficients (r) between toxic and potentially toxic elements contents were calculated. Elements in which the relationship between the content is described by a correlation coefficient exceeding 0.5 with a significance level of at least 95% were combined into a single geochemical association. During the calculation of correlation coefficients, all values of manganese concentrations were normalized.

To study the physical-and-chemical parameters of soil substrates used for coal dump reclamation in Western Donbas, in particular black soil and red-brown clay; to investigate the Bioconcentration Factors, Translocation Factors and Tolerance Index of indicator plants; to compare the different additions to soil substrate in order to increase the phytostabilization by testing in model laboratory experiments examples of different biosorbents and biomeliorants.

Purpose. Studies of energy distribution at different frequency ranges in the process of propagation of cavitation-pulsation action on an array of rocks found that the maximum value of energy is realized at the pulse repetition frequency and the more pronounced the more cavitation bubbles. Methodology. We have formalized the general problem, which is reduced to the choice of technological solutions to intensify the destruction of rock, taking into account the frequency distribution of energy from the peeling of cavitation bubbles at the bottom of the well.
