The determination of gas content and gas amount in the extraction areas is important for safe coal production.
The are different methods for forecasting of gas content and amount:
- Methods for regions with high gas content and their determination of parameter
The following data are necessary to forecast the gas content and to evaluate the amount of CMM
- characteristis of coal mining process, available amount of methane in the mined region or closed mining shafts
- plan of the mine
