Pneumoconiosis Field Research: Environmental conditions at Vane Tempest Colliery, 1971

This report tabulates respirable dust concentrations and composition at Vane Tempest Colliery for the period April 1971 to March 1972. Information regarding seams worked, outputs, methods of working, dust suppression and manpower together with the associated dust concentrations is presented in a series of face charts.At Vane Tempest Colliery^ the coal face mean respirable dust concentration was 4.2 mg/m3. The mean ash content of respirable dust sampled was 32.1 per cent and the mean quartz content 3.7 per cent, representing a concentration of O.l6.mg/m3. “”
