Device for in Situ Measurement of Coal-cutting Forces.
MISSING :25 pages
The Bureau of Mines devised and demonstrated a portable linear- cutting tester that directly measures and records the in situ cutting forces required of continuous-mining machine picks to cut coal in underground mines. It requires only two operators to transport and operate the tester, which can be assembled and operated through a complete test cycle within a single mine work shift. This report reviews the factors considered in the design and development of the tester and the results of its system verification testing at coal mine sites.
