Abstract

The project reported here undertook a review of the communications systems in use at British Coal collieries and aimed to identify the requirements for an integrated communications architecture that satisfies the needs of a modern colliery. An analysis led to the conclusion that most of the requirements for an integrated colliery network would be satisfied by extending the surface local area network underground using fibre optics, and adopting a topology that provided a high degree of redundancy. This would be overlaid with a set of communication protocols that ensured secure and fault tolerant transfer of information. Problems with the installation of fibre optics have been overcome by using a cable technology and installation method, known as blown fibre. It was decided to carry out laboratory tests on the basic network strategy and a series of underground trials to determine the practicality and durability of the blown-fibre technique. Unfortunately, because of the major contraction in the coal industry that took place during the project an underground trial site could not be found and the project was terminated.
