As part of its continuing program in protecting the health and safety of the nation's coal miners, the Bureau of Mines, Department of the Interior, presented on November 3-4, 1969, a Symposium on Respirable Coal Mine Dust. The Symposium was cosponsored by the American Mining Congress, the National Coal Association, and the National Independent Coal Operator's Association. Within recent years it has become evident that a large number of our coal miners develop a severe occupational respiratory disease commonly referred to as "black lung," but more appropriately designated as "coal worker's pneumoconiosis." Studies in the United States as well as in European countries clearly demonstrate that prevention of the disease is related to the control and suppression of respirable coal mine dust. This Symposium dealt with the various engineering methods of controlling dust in underground coal mines including ventialation, water suppression, machine design, and dust collection; and a discussion of respirators and life support systems. The merits of these various procedures and their potential application to underground coal mining were examined. In every case attempts were made to secure outstanding talent in each of the major areas discussed. The proceedings of the Symposium should constitue a reference on current technology for dust control. The Symposium helped to delineate those areas where additional research is needed and highlighted the necessity for concentrated efforts by both industry and Government for intensive research and investigative programs on engineering procedures to control respirable coal mine dust within prescribed hygienic limits. Hopefully, research will move so rapidly that within a reasonably short time this publication will be out of date in terms of dust control technology
