Abstract Proper coal mine degasification minimizes, if not eliminates, the danger of mine explosion and the loss of liv It also cuts down the cost of coal production These two advantages alone justify degasification of all moderately and highly gassy coal seams Moreover, the recovered gases can be gathered, processed, and sold for added .
Coal mining and chronic obstructive pulmonary disease: a ,
The potential of coal mine dust to cause disabling pneumoconiosis has long been recognised, but research now suggests that pneumoconiosis is not the only respiratory hazard of coal mining Over the last 30 years evidence has accumulated that miners also experience an excess of chronic obstructive pulmonary disease (COPD), and this has led the British Government to classify chronic bronchitis .
