Title

Testing of the Prototype Hydrominer in a Surface Coal Seam

Abstract

In May 1975 the U. S. Bureau of Mines contracted with the University of Missouri-Rolla, Rock Mechanics and Explosives Research Center to develop a Hydrominer modification to a longwall shearer unit, wherein the rotating pick-laced drums and connecting gear drives are replaced by a water jet cutting head. Initial design and successfully completed trials of this first test-bed type Hydrominer are dealt with. Particular reference is made to the design of the cutting head. Test results show that the Hydrominer can effectively mine coal with no dust.
