REDUCTION IN ENVIRONMENTAL IMPACT OF UNDERGROUND COAL MINING WITH BACKFILLINGMETHOD OF EXERCISE WORK FOR SMALL COAL CUTS WITH THE APPLICATION OF AN ADVANCED MINE OPERATING COMBINE

In the northern regions with decentralized energy supply, the social importance of energy supply comes out on top. In these areas there are many small dispersed energy consumers that generate heat and electricity from small autonomous power plants, while coal is one of the key fuels. Coal delivery to remote Arctic consumers is carried out with two, three or more transshipments and storage on the way, resulting in its significant loss due to spills, blowing, leaching at all stages of transportation, reducing the quality characteristics of coal due to its crushing, oxidation and clogging with residues other goods. The article proposes to carry out the transportation of coal to small consumers in soft containers, ensuring the safety of the qualitative and quantitative characteristics of the mineral. It is proposed to develop small coal mines using a mining combine equipped with a sorting plant to extract small coal fractions, a system of pneumatic transport of small fractions and an automatic packaging unit for differentiated packing of large and small fractions of coal produced into soft containers. The method allows mining operations at the same time sorting and packing of coal with a minimum amount of mining equipment, which is especially important when developing small cuts.

Keywords
