Inexpensive method helps predict methane content of coalbeds.
Coal Age 1976 Jun; 81(6):102-106
Researchers at the Bureau of Mines Pittsburgh (Pennsylvania) Mining and Safety Research Center have developed an inexpensive method of calculating the gas content of a coalbed from exploration cores before mining. The resulting data and design charts can be used to estimate the gas resource potential of the coalbed and to design adequate mine ventilation systems to handle any problem. Cost of the analytical equipment is less than $100, and the time required to conduct the tests is normally less than 1 month.
