The presented study shows the impact of changes in the content of continuing education programs on the assessment of the quality of courses by students in the center of additional vocational education. The developed system of evaluation and input and output questionnaires made it possible to identify point changes that need to be implemented to improve the quality of both the course attendees and the customers. The presented system of impact on the quality of professional development through continuous balancing of the thematic content of the program of additional professional education allows managing the development of the competencies of employees. Point changes in the proportions of the content blocks of the programs made it possible to achieve the optimal set of topics that satisfies the needs of the customer in terms of developing certain competences in the employees, as well as the course participants themselves in terms of interest in learning and personal growth. The developed approach makes it possible for the company of the customer to introduce a system of continuous professional training, advanced training and retraining of personnel by controlling the level of competence of trained employees to improve performance.

The article covers the issues of increasing the efficiency of tunneling&cleaning combines “Ural”, widely applied at domestic potash mines. It is pointed out that it is possible to provide rational parameters of the process of destroying potash arrays with cutting tools of the executive bodies of mining combines. This assumption is based on the assessment of the drivers load which will reduce the specific energy consumption for ore extraction and will reduce the number of small unenriched classes in breakage products. The authors substantiate rational regime parameters of the operation of the planetary-disk executive bodies in the Ural combines. A method for automatic control of the tunnel&cleaning combine “Ural” is proposed, which ensures the implementation of the process of destruction of the potash massif with rational cutting parameters on the basis of information on the drivers load.

The article discusses the extraction of solid mineral resources (SMR) from the bottom, such as ferromanganese nodules (FMN) and cobalt-manganese crusts (CMC), occurring in both offshore and deep regions of the World Ocean. For separating and lifting the water surface is used mining complex, which includes a hydraulically dragheads and intermediate capsule with atmospheric pressure introduced into the of extraction process in order to increase energy efficiency through the organization of a two-stage hydroascent, the first stage is carried out by external hydrostatic pressure. To determine the optimum depth of immersion of the intermediate capsule composed mathematical model. It is based on the sustainable hydroascent provided at the first stage transport (from the bottom to capsule), and reducing power consumption slurry pump performing the second stage transport (from the capsule to the sea surface). In determining the rational immersion depth were taken into account design features of slurry pipeline, mine geological parameters, the parameters of extracted minerals, performance of dragheads, the slurry flow parameters, such as concentration, consistency, density. Presents an example calculation and determined the optimal capsule insertion depth for offshore geological environments.
