Mechanism of Increasing the Permeability of Water-Bearing Coal Rock by Microwave Steam Explosion

Table 4

Temperature rise rate of coal rock samples with different water contents under microwave irradiation.

Water content (%)	Volume ratio (%)			Effective parameters of coal rock mass			(°C/s), initial temperature 25 °C	Predicted temperature (°C)	Measured temperature (°C)	Error (%)
