Pneumoconiosis Field Research: Environmental Conditions at Vane Tempest Colliery, 1969

This report tabulates by face and site, in a series of charts, the respirable dust, ash and quartz concentrations for the period January, 1969 – March, 1970 at Vane Tempest Colliery. It is the second report of the series in which dust measurements were made by the M.R.E. Gravimetric sampler only.Information on methods of working, outputs and manpower is also given.The colliery had a coalface mean respirable dust concentration of 4.3 mg/m3 . The mean ash content was 29 per cent and the mean quartz 3.3 per cent (concentration 0.14 mg/m3 ).
