Abstract
The global challenge facing the domestic mining industry is to ensure "decarbonization" of coal mining to achieve sustainable development of mining production. In this regard, the purpose of the work was to improve the methodology of determining the step of artificial strips of partial filling to reduce the emission of climatically active gases, by increasing the stability of degasification wells under development. The result of the work was the approbation of the methodology of estimation of dynamic spatial and temporal changes in methane concentration during the formation of the maximum roof span. In addition, the value of the limit state of the roof rocks (150 m), which determines the frequency of construction of artificial structures in the area of the longwall mined-out space, was determined.
Keywords
Sustainable production, roof stability, methane emissions, gas flows, backfilling, underground wells.
