Determination of critical value of an outburst risk prediction index of working face in a coal roadway based on initial gas emission from a borehole and its application: A case study
Fuel(2020)
Abstract
•A determination model of critical value of prediction index is proposed.•Apparent density and briquetting pressure of coal briquettes is exponential.•The characterization of initial gas emission from a borehole has three categories.
