Integrated justification of technological structure for coal mine

Employment of up-to-date high-performance equipment in longwalls has created conditions for the increase in concentration of mining operations by means of reduction in number of longwalls, and has simplified the technological structure in the majority of coal mines in Russia at the preserved or even enhanced production capacity. At the same time, the longwall mine structure which is mostly used in underground mining of gently dipping coal seams can impair mining safety and efficiency. The aim of this study was to justify a sound technological structure of high-productive longwalls in mining gently dipping coal seams. The scientific novelty of the research consists in the integrated approach to selecting a rational technological structure of a mine to ensure safe and economically efficient underground coal mining. The advantages and disadvantages of a longwall mine are discussed. The capabilities of protective mining of coal seams as an effective regional ground control method in extraction of multiple coal seams under high risk of dynamic phenomena are described. The protected zone parameters for longwall mining of a protection seam are determined. It is discussed how it is possible to lift restrictions placed on longwall capacity by gas criterion in a group of gasbearing coal seams by means of advanced extraction of a less-productive seam with simultaneous efficient drainage of the mined-out void and reduction in methane content of undermined coal. Applicability of different variants of such technological structure and sequence of mining is considered in an idealized geological situation. The ranges of efficient use of different technological structures are identified. The recommendations on selection of a rational technological structure for mines operating in different geological conditions are given.

Keywords: underground mining, coal seams, technological structure, longwall mine, rational mining sequence, protective seams, geodynamic safety, coal methane content, methane release control, engineering-and-economic performance.
