Abstract
In this article, variants of technological designing of new mining enterprise levels for obtaining the skills of engineering task execution are considered. The complex approach for the justification of a mine’s parameters is examined. The com- binations of quantitative and qualitative parameters for designing new coal-face and preparation works, transport, ven- tilation, and draining-out of gases, pumping, and mineral deposits while keeping cost reduction in mind for all stages of mining enterprise operations are presented. The obtained results allow us to lay the foundations for optimizing the pa- rameters of the development system and the rational order for the coal reserves, under the changing mining and geo- logical conditions of coal field deposit development. Conclusions regarding the implementation of the multivariance solutions in new coal mine level designing are made on the basis of undertaken investigations. The obtained results with sufficient accuracy in a practical application can be used to determine the development of new coal mine levels.
Highlights
Coal is the main fossil fuel used in the power generation
The mine as an operating mining enterprise is a set of many interrelated production processes and operations carried out with the help of machines and mechanisms according to a certain technological scheme
The general production processes interface circuit in a single continuous interaction through excavations and mechanization which means they can be defined as a technological scheme of the mine
Summary
Coal is the main fossil fuel used in the power generation. At the same time, coal is the most abundant energy resource and will continue to be the dominant energy source for the 20-40 years, but in the Ukraine even up to 50-60 years (Piwniak et al, 2005; Petlovanyi et al, 2018). Assessment of new coal mine levels at the stage of their design, development and operation should take into account the current and future needs of the national economy (Piwniak et al, 2007). From this point of view, the volume of reserves and mineral content in them play the main role (Griadushchiy et al, 2007). After all, when including the natural resource reserves on the coal mine balance sheet, where it is possible to justify mine development, and work them out technically, ecologically and in a cost-effective way, the geomechanics of the seams and rock massifs faulting, the complexity of coal excavation and other associated minerals, including methane gas become irrelevant (Khomenko et al, 2018; Saik et al, 2018; Zhao,et al, 2019)
