“…In the first case, it is determined purely geometrically from one centre of mass to another, without taking into account the mining-and-transport complex operation. In the case of simulation modelling [24]- [27], this figure is summed up from the actual distance travelled by the dump trucks from the three points of loading overburden rock, taking into account the number of travels in each direction, which, in turn, also depends on the models of loading and transport equipment [28]- [30].…”

Purpose. The research purpose is to develop and adapt the existing scientific-methodological, as well as software and information base for managing the geotechnological complexes to implement the process approach at the level of design and operation of mining-and-transport complexes during opencast mining. The development is associated with the coverage of more and more relevant options for excavating-conveying, as well as excavating-automobile-conveying mining-and-transport systems used in quarries. Methods. The methodology for managing the geotechnological complexes involves an adequate step-by-step accounting and appropriate operational regulation of all the main factors in specific mining-engineering, mining-geometrical, mining-and-geological, economic and organizational conditions. The method of simulation logical-statistical modelling of mining-and-transport processes is used as the main method. Findings. The results indicate that simplified analytical approaches and inadequately considered factors that have a significant impact on the efficiency of mining operations lead to significant errors (10-20% or more) that determine the real practical profitability of the mineral deposits development. Originality. Scientific novelty is an integrated approach to a single research object, which is a geotechnological complex, a unique simulation logical-statistical modelling of mining-and-transport processes, the economics of process management, as well as integrated and corporate process management. Practical implications. The obtained results of an integrated technical and technological audit of a project for mining the coal deposit, with sufficient accuracy for practical application, will ensure the methodological base development for the designing, planning and management of mining and mining-transport operations, as well as an increase in the efficiency of scientific and scientific-practical research in this direction when solving the practical tasks of mining sector.

“…Of course, the determination of the boundaries of open pit mining should be carried out taking into account the conditions of stability of the massif of boundary rocks, which are performed by modern remote methods [17,18]. When determining the boundaries of the open pits according to known calculation principles, the economic calculating ratio is calculated according to technical and economic indicators, which are achieved at the time of design and its value is constant [19][20][21].…”

The article considers the determination of the final contours of the open pits. One of the problems of development of iron ore deposits at the present stage of development of opencast mining is described, which consists in the fact that in most open pits their working contours on the surface have reached final position. In these conditions, it is necessary to reevaluate the capabilities of the raw material base for further operation of mining enterprises. The analysis of scientific achievements in the decision of the final definition of the open pits` contours is executed. The well-known principle of determining the boundaries of opencast mining, the principle of which is to determine the boundaries based on a comparison of the allowable cost of ore production with the expected for the designed open pit. On the example of the open pits, which reflect the characteristic features of the development of steep-dipping deposits of Ukraine, the influence of current overburden ratio of the existing open pits on the economic overburden ratio, which serves as the main criterion in determining the boundaries of opencast mining for the designed open pits. A method for determining the boundaries of the open pits has been developed, which provides for the use of the economic overburden ratio of opening as a value not constant but variable over time, and one that depends on the change of current coefficients of opening in open pits-competitors. As a result, the theory in the field of determining the final contours of the open pits is improved. The new method differs from the known ones by taking into account the change in the economic overburden ratio over time, as well as determining the impact of technological indicators of open pits - competitors on the final depth of the designed open pit.

The economic efficiency of the enterprise and the length of its operation, the full utilization of mineral reserves and the total cost of operation depend on the selected depth and boundaries of opencast mining. In such conditions of the deposits' development it is necessary to evaluate the capabilities of the raw material base for the further development of the mining enterprise. The basis for determining of the border overburden ratio is on the condition that the price of manufactured marketable output of the designed enterprise should not exceed the price of the same marketable output in the world market. The realization of this condition is achieved analytically. This takes into account the impact of the rate of return on the final depth of the designed open pit. A new method of determining of the border overburden ratio is developed, which ensures the competitiveness of iron ore concentrate in the world market. The value of the border overburden ratio is developed for the Pershotravnevij open pit of the Northern mining and processing plant, depending on the situation of the iron-containing products' prices, which ensures the competitiveness of marketable iron-ore output in the domestic and world markets.
