Purpose. To improve the theoretical and methodological postulates for motivation and remuneration system providing the basis for the generalization of the conclusions and recommendations for further development of management at enterprises. Methodology. In order to improve the theoretical and methodological postulates for motivation and remuneration system we have used scientific and special methods: method of critical analysis and synthesis of theoretical studies, method of systematic approach, method of economic and mathematical modeling. The timeliness and accurateness of the calculations have been provided by Excel 7.0 software. Results. We have proved that the mechanism of compensation should be organically integrated into the strategy of mining companies and it should be the main object of improving the systems of personnel management in the current economic situation. Originality. On the base of the flexible fare concept we have improved so-called dynamic model of wages. In this model, the tariff should have the main incentive load. The optimal wage structure has following proportions: rate - 85%, the periodic premium for individual achievement - 10%, the premium for the results of the company as a whole - 5%. Periodic bonus should encourage employees to make additional efforts related to the development of new technology and introduction of new forms of work organization, mastering related professions, working methods, etc., which lay the foundation (base) to the productivity increase. Practical value. A basic scheme for the formation of wages in relation to strategy development management of mining enterprises, which is a set of individual integrated components, intended to meet the needs of the employees and the interests of employers, which correspond to the general concept of the innovation development of Ukraine.

Purpose. To choose the simplest types of explosives and provide the theoretical and practical rationale for the change-over to economical, safe and environment friendly TNT-free explosives. Methodology. To determine the prospects of TNTfree explosives use in ore mines with underground production we have used following scientific and special methods: methods of mathematical, statistical and graphical simulation, method of systematic approach, method of economic and mathematical modeling. Findings. The effectiveness of use of simple explosives in the underground conditions depends on strength and water content of rocks, as well as on the physical stability of the explosive mixture. During blasting it is necessary to exclude the use of explosives with oxygen disbalance or containing unstable components which vary depending on the geological conditions in the wells. Originality. We have found out that the explosive mixtures of equal chemical composition but different by physical features this displacement have different values of the critical limit and dcr, dpr charge diameter. Thus, the mixtures of diesel fuel with nonporous nitrate and with porous nitrate in cartridges with hard shell have d cr of 120-160 mm and 70-100 mm respectively. Critical parameters of detonation and explosive characteristics of igdanite with charge diameter under the limit strongly depend on the properties of nitrate granules, their porosity, absorbency regarding diesel fuel, surface area, etc. Practical value. To supply the mining companies of Ukraine with waterproof and safe explosives it is recommended to use emulsion explosives of "EPA-R" brand of 2 nd class for loading cartridges with diameter of 32-90 mm into wells. These explosives are initiated from a blasting cap or the detonator fuse and are used in mines which are not dangerous by of gas and dust parameters. By performance and safety the packaged explosives of "EPA" brand excel traditional ammonite no.6 ZhV. Source
