The State-of-the-art in Continuous Mining Machine Bit Technology.
NTIS: PB/225-633 Available for Reference At Bureau Libraries :211 pages
After many years of research, the occurrence of pneumoconiosis, black lung disease, among miners has been related to the mass of respirable coal dust to which mining personnel have been exposed. As a result of the restrictions imposed by Public Law 91-173 in 1969, much work has been done in determining methods of either eliminating or suppressing respirable dust. The purpose of this project was to determine the state-of-the-art in continuous-mining machine bit technology, particularly with regard to dust production. The scope of the survey included visits to bit manufacturers, mining companies, mining machine manufacturers, and consultants in order to determine what bits are the best available, why they are the best, and the level of acceptance of past and present bits by the mining industry.
