Розробка заходів щодо зменшення газового балансу шахти «Краснолиманська» при відпрацюванні пласта k5

Abstract

The scheme of the disclosure, the way of preparation of the mine field and the system of development used are analyzed. The choice and justification of means of mechanization of treatment works is carried out. The mine variant of degassing of methanogenic sources has been analyzed, its deficiencies have been identified. Measures have been developed to reduce the influence of the gas factor on the work of the treatment face. The parameters of these measures, their economic efficiency in comparison with the mine option on the main elements of expenses are calculated: wages, materials, electric power and depreciation. The specific costs of degassing per 1 ton of coal mined in the lava will decrease by 1.69 times, with a 2.6-fold increase in the pressure on the treatment blast.
