From a commercial viewpoint, mine methane is the most promising object in field of reducing emissions climate-active gases due to circular waste management. Therefore, task this research estimate technogenic reservoirs resources when implementing management concept. The novelty authors’ approach lies reconstructing response space for dynamics release from front and cross projections: CH4 = ƒ(S; t) L), respectively. established polynomial dependence nonlinear changes concentrations mixture extracted by type 4 wells massif undermined as result mining full-retreat panel. And distance face start panel reduced 220 m. For reason, emission methane, case degasification network disruption 15 days, can amount more than 660 thousand m3 only no. 4.

At the current stage of development, transition to a circular economy is single option achieve sustainable mining. Purpose was identify direction for mining tailings usage based on waste management. The novelty author's approach lies in regulation mechanical treatment slag optimize backfill composition. methodology involved study (slag) obtained from major (eight) metallurgical plants Russia. For mathematical processing primary data, smoothing and deterministic three-dimensional interpolation methods were used. As result, first time it has been established that ultimate uniaxial compressive strength after increases by logarithmic laws. curing 10 days 90 (with addition Ca or Si) 21 % (7 23 %). possibility completely replacing traditional cement binder with composite proven. It use activation (both chemical) makes possible increase characteristics samples their curing. principle organizing production implemented, which provides intermediate products (blast furnace granulated slag), previously classified as technogenic waste, closed cycle. introduction this will eliminate (minimize) formation man-made waste. scientific merit slag) allows implementation
