How computerized instrumentation monitors coal mine roofs.
Min Eng 1976 Sep; 28(9):40-43
A computerized instrumentation system has been developed by the federal Bureau of Mines, Spokane, Washington Mining Research Center, for measuring critical parameters needed to examine the structural behavior of a coal mine roof support system. This system provides instantaneous computation and plotting of load, load rates, deformation, stress, opening closure, etc., in an actual production situation, using conventional mining techniques, such as room-and-pillar. The measurement system provides total or random access of up to 400 underground instruments or measurement points, and consists of a minicomputer-acquisition system that can be located up to 2 miles underground. All instrumentation is advanced with the mining cycle and is installed within a foot of the face.
