Tunnelling Machine Instrumentation for Use in Coal Mines

摘要

An instrumentation system has been developed to monitor the cutting and overall performance of a full-face tunneling machine. Information from transducers on the tunneling machine was electronically conditioned and then transmitted to the surface for recording and subsequent analysis. A Certificate of Intrinsic Safety has been obtained for the equipment, allowing its use in a coal mine. (Copyright (c) Crown Copyright 1979.)
