Pneumoconiosis Field Research: Environmental Conditions at Vane Tempest Colliery, 1970

This report tabulates respirable dust concentrations and compositions at Vane Tempest Colliery for the period 5th April, 1970 to 3rd April, 1971 Information regarding methods of working, outputs and manpower is also given.The colliery had a coalface mean respirable dust concentration of 5.2 mg/m3 . The mean ash content of the respirable dust was 37.6 per cent and the mean quartz content 4.4 per cent (concentration 0.21 mg/m3).The ‘volunteer carrier’ system of sampling, which was introduced during the period, is described. “”
