IC 7248 Some Preliminary Data On Methods For Allaying Coal Dust In Tipples And Cleaning Plants ? Introduction

The control of coal dust on coal tipples and cleaning plants has not been given the consideration that is afforded underground dust hazards. This apparent oversight is undoubtedly due to the general opinion that coal-dust accumulation in tipples or cleaning plants does not present the same type of hazard that it does underground. That this opinion is at least in part a fallacy has been proved many times, and the Bureau of Mines has on record many examples of explosions in tipples and cleaning plants.3/ In addition to this explosion hazard, coal dust is considered by sonic authorities to be injurious to the health of individuals exposed to it.4/ Obviously, it reduces visibility and contributes materially to accident hazards and the discomfort of the employees. Several companies have recognized this dust hazard and the advantages derived from controlling it; consequently, they have installed equipment to allay and control the dust on, their cleaning plants and tipples. The object of this paper is to. Summarize briefly some of the methods new in effect.
