Improvement of Intensive In-Seam Gas Drainage Technology at Kirova Mine in Kuznetsk Coal Basin

One of the ways to resolve “green energy-economic development” dilemma, in which coal industry is situated, by improvement technologies and integrated use extracted resources, including methane gas as a clean energy source. Using example Kirova mine, located Kuznetsk basin—one ecologically unfavorable mining regions Russia—this article discusses an technology for extraction coalbed (ECBM), makes it possible reduce greenhouse (methane) emissions improve safety intensity mining. The with its 3 Mt production 2019, one leaders Russia. available equipment has potential significantly increase output; however, limiting factor this. customary approaches seam degassing have already been petered out. miners mine science are facing challenge validate test alternative ensure effective in-seam drainage prior vigorous This gives account track record used pre-treat seams intensive safe extraction. suggests, at first stage, hydraulic loosening target through wells drilled from surface (SSHL), then fracturing (HF) boreholes underground development headings, followed high-permeability coal-gas reservoir created standard wells. Results presented this paper field testing improved SSHL technique. Findings on parameters HF technology. Methodological recommendations offered selecting viable
