Some Aspects of the Compatibility of Mineral Mining Technologies

Abstract

Sometimes in mining, it is necessary to combine di erent extracting technologies within one enterprise. So, in this paper, the analysis of scienti c and technical mining operations with combined technologies is carried out, and the search for structure and their operation in the mining enterprise is performed. The processes and technological parameters of mineral extraction by two fundamentally di erent technologies are investigated in detail. Due to the introduction of additional technologies, it is possible to involve sub-standard reserves in the production process, and an algorithm for determining the technological parameters is developed. This algorithm consists of criteria that make it possible to nd compatibility in the work of one or more development technologies while maintaining an e ective level of extraction. To do this, all processes at the enterprise are grouped: by degree of exploration, feasibility and economic e ciency. For each of them, certain coe cients were determined on the example of the operation of two speci c combined technologies: the extraction of uranium ores and coal. For each group of criteria, certain coe cients are identi ed that allow assessing the feasibility of applying technology in their area. Their product is a general coe cient of compatibility, which shows the feasibility of introducing additional technology at the enterprise with the feasibility study. It de nes the amount of funds invested in the development of an enterprise to achieve e cient mineral extraction with combined technologies within one enterprise. This point can be used to predict the grade variability of stockpiles from the origin source and the methodology allows characterizing the iron grades within stockpiles without any extra sampling.

Some Aspects of the Control for the Radial Distribution of Burden Material and Gas Flow in the Blast Furnace

“…The complexity of the problem results from the high level of dust content in the space above the burden, as well as the boiling and fluidizing of the burden surface layer caused by the gas flow [24][25][26][27]. The attempts at solving the problem by the application of mechanical, microwave and even x-ray monitoring instruments failed [28].…”

Research into the moisture influence on the physical-chemical tuff-stone characteristics in basalt quarries of the Rivne-Volyn region

“…At the same time, for the integrated mining and processing of mineral raw materials, it is necessary to solve a number of geotechnological problems related to improving the mining system [6 -8], optimizing planning decisions [9,10], taking into account the ecological component of minerals mining and processing [12 -16], as well as determining the effect of moisture together with its filtration processes on the physical-chemical properties of mineral raw materials [17 -20]. Particular attention should be paid to modern technologies for the integrated mining and processing of raw materials based on the latest methods [21 -23].…”
