Pneumoconiosis Field Research: Environmental conditions at Lady Victoria Colliery 1980/81

This report tabulates respirable dust concentrations and compositions at Lady Victoria Colliory for the period April 1980 to March 1981, the date at which production ceased.Information regarding scans worked, outpats, methods of working, explosives used, dust suppression, manpower and mean travelling times to faces, together with associated, dust concentrations, is presented in a series of face charts and tables.At Lady Victoria Colliery the mean coalface respirable dust concentration was 3.5mg/m3. The mean ash content was 48.3 per cent and the mean quartz content 8.6 per cent (18.1 per cent of the ash) representing a quartz concentration of 0.3mg/m3.Face total dust concentrations are tabulated and were 7.9 times as high as the respirable dust concentrations. Total dust concentrations for development, outbye, and surface groups are noted.
