Environmental conditions at Vane Tempest Colliery, 1968

This report tabulates respirable dust concentrations in mg/m for the period August 1968 – January 1969 at Vane Tempest Colliery, and is the first report in which all dust measurements have been made using M.R.E. Gravimetric Sampler only.Information regarding methods of working, outputs and manpower is given. For each face occupation, the concentrations of the respirable dust, together with the ash and quartz concentrations for each face site are listed.Vane Tempest, a mechanised colliery, had a coalface mean respirable dust concentration of 4.8 mg/m3. The ash content of the respirable dust was 27 per cent and the mean quartz content in sample was 5 per cent (concentration 0.15 mg/m3). “”
