Abstract:
Parameters for degassing outburst-prone seams using hydraulic fracturing are determined. It is proposed that the distance between seam drainage boreholes be determined based on the condition of reducing gas content to safe emission limits and taking into account the filtration properties of the coal. Dependencies are provided for calculating gas permeability coefficients depending on natural factors to determine the total amount of methane released into the drainage borehole. The results of studies on the relationship between injected fluid pressure, coal properties, and seam bedding conditions are presented. It has been established that the pressure of fluid injected into a seam depends on the physical properties of the coal, the depth, and the dip angle of the seam, and not just the burial depth. It is noted that the physical properties of the seam can be approximately accounted for by the average value of Poisson’s ratio and the yield of volatile substances.
