The paper discusses enhancement of gas drainage well productivity in coal seams using the hydraulic fracturing technology. Filling of a fracture with proppant provides a long-term increase in the gas drainage well performance. The results of the laboratory experiments to determine coal permeability under various stress conditions show that proppants significantly reduce fracture compressibility and the propped fracture becomes less sensitive to stress variations.
