Abstract EN
With an increase in mining depth and production, the intensity and frequency of outburst of coal and gas have a tendency to increase.
Estimating the intensity of outbursts of coal and gas plays an important role because of its relation with the risk value.
In this paper, we described the semiquantitative relations between major parameters and intensity of outburst based on physical experiments.
The results showed increment of geostress simulated by horizontal load (from 1.4, 2.4, 3.2, to 3.4 MPa) or vertical load (from 2, 3, 3.6, to 4 MPa) improved the relative intensity rate (3.763–7.403% and 1.273–7.99%); the increment of porosity (from 1.57, 2.51, 3, to 3.6%) improved the relative intensity rate from 3.8 to 13.8%; the increment of gas pressure (from 0, 0.5, 0.65, 0.72, 1, to 1.5 Mpa) induced the relative intensity rate to decrease from 38.22 to 0%; the increment of water content (from 0, 2, 4, to 8%) caused the relative intensity rate to drop from 5.425 to 0.5%.
Furthermore, sensitivity and range analysis evaluates coupled factors affecting the relative intensity.
In addition, the distinction with initiation of outburst of coal and gas affected by these parameters is discussed by the relative threshold of gas content rate.
