 The decarbonization of the mining industry can be achieved through the closure of energy generation, cogeneration of coal mine methane, and internal consumption of the mine. Additionally, known issues with deep underground mining prevent the realization of the potential of man-made gas reservoirs due to the deterioration of the conditions of developing reserves of georesources. To ensure sustainable development, the following steps should be taken. 1. Improving recommendations for the substantiation of drilling parameters for undermined drainage boreholes for increasing methane production from unconventional coal gas collectors. 2. Smoothing, less, of the experimental data of two similar types of wells. 3. Deterministic interpolation methods in combination with a three-dimensional representation of the response function in GNUplot. 4. Increasing the inclination angle from 40 degrees to 60 degrees leads to a significant transformation of the model of the studied process, accompanied by a decline in the dynamics of methane emission and a decrease in the distance of the productive work zone of this type of well-from.
