Due to recent increased competition in the energy market, the British Coal Corporation needs to increase production efficiency by increasing machine utilisation. To do this necessitates a comprehensive knowledge of plant operation and of machine performance over the full operating spectrum, as well as a thorough understanding of strata behaviour during the coal extraction process. Portable underground instrumentation will have an important part to play. It will complement existing on-board surveillance devices, providing additional or more detailed on-site information. It will also enable parameters to be recorded in areas where permanent instrumentation is not available. A portable solid-state modular instrumentation package has been developed, specifically for use in operational and investigational applications. The interchangeable modular flexibility of the system permits a variety of configurations designed to suit specific applications. The system is compatible with existing data transmissions systems for on-line monitoring or long-term data gathering. In-situ verification that data have been successfully recorded and the ability to display data underground are essential features. Additionally recorded data can be retrieved underground and manually brought to the surface for computer analysis. All the instrumentation developed complies with recognised standards concerning analogue signals in coal mines, and is certified intrinsically safe to BS1259 : 1958 or is in the process of being so certified.
