For coal seams with high rockburst risk, the spacing of pressure relief holes can be set to be less than or equal to 0.5 m, which can greatly improve the energy dissipation effect of coal seams. The studies can provide a theoretical basis for the optimization parameters of pressure relief holes for rockburst prevention.
Coal Seam
Methane is the major component of gas in coal, comprising 80%–95% of the total gas content. The balance is made up of ethane, propane, butane, carbon dioxide, hydrogen, oxygen, and argon. All coal seams begin to oxidize when exposed to ventilation air in a mine and produce some carbon monoxide and hydrogen sulfide.
