Firedamp drainage at Cardowan and Valleyfield collieries
Determination of appropriate methods of borehole drainage of firedamp having regard to pressure at which gas would be tapped; investigation of best position, angle, diameter, length and distance apart of boreholes, and duration of gas outflow from boreholes drilled in different directions; effect of firedamp drainage on quality of ventilating air passing through workings. (See also Instn Min Engrs -- Trans v 114 pt 7 Apr 1955 p 579-604 (discussion) 604-10)
