A dust survey was carried out in a group of eight haematite mines, prior to the use of water for dust control, and was repeated later, when practically all dust-producing sites were subjected to wet treatment. No changes in ventilation or other procedure were made in the intervening period. Settled dust samples had been shown to contain from 9 per cent. to 16 per cent. of free silica, and the ...

The local abundance of specular haematite within the interstices of coarse-grained sandstones within the Coal Measures suggests that these too may have acted as mineralising aquifers in suitable structural settings. If so, hitherto undiscovered haematite orebodies could exist to the west of the known west Cumbrian orefield.

oflung cancer associated with haematite mining. During the 20-year period there were 42 deaths attributed to lung cancer among iron mine employees resident in the study area: 36 ofthese occurred in miners working underground, which was significantly greater than that expected from local non-mining (20-6 deaths) or national (21-5 deaths) experience.
On the one hand, improvement in income can translate into better nutrition and health care. On the other, environmental degradation can adversely affect health status, including diarrhea, cough, and cognitive development. Overall, the local effects of mining on child health are mixed and far from uniform across countries.
Although a satisfactory reduction in dust concentration had been attained by wet methods in a group of haematite mines, as described in the previous abstract, excessive quantities of dust were still being raised by mucking operations. This was dealt with by increasing the ventilation, either by coursing main air directly through the stopes, or, in the case of dead ends, by forcing air in with...
