Golder RMT

Golder RMT* is a specialist team providing rock mechanics consultancy in the field of mining and tunnelling together with the manufacture and supply of a range of geotechnical instrumentation for in situ measurements of ground movements and rock stresses.

We specialise in the use of quantitative investigations of rock behaviour, and reinforcement performance, supplemented by computer modelling, to solve geotechnical problems. Particular areas of expertise include tunnel support, pillar behaviour and mine layout design. Our investigation techniques have led to significant advances in the understanding of excavation behaviour and rock reinforcement design in complex stress fields in mines, resulting in improved performance and lower costs. Based on this experience, we provide practical and theoretical training in rock reinforcement techniques for mining personnel worldwide.

Our team of 26 professionals, based at Bretby, Derbyshire, UK, are qualified in a range of disciplines allied to geotechnics and are experienced in solving rock mechanics and mining problems in coal, soft rock and hard rock mines. As well as providing services to the mining industries in the UK and South Africa, staff have worked for clients throughout Europe, Russia, USA, Canada, India, Africa, Egypt, Australia and Japan on assignments including rock reinforcement design, pillar design, mine layout and supply of geotechnical instrumentation.

We also undertake a significant research and development programme. This allows the company to continually develop its services and investigation techniques. Current research projects include major European Community and HSE funded projects into aspects of coal mine roof reinforcement and layout issues. These projects include collaboration with other European research organisations and mine operators.  See our Research page for more information.

Our on-site facilities at Bretby include instrumentation and testing laboratories. Rock property tests, including tri-axial testing using a 1,000kN stiff test machine, are routinely undertaken. We have also developed laboratory-based tests for testing rock reinforcement materials in rock to determine in situ performance characteristics.

We manufacture a wide range of geotechnical instrumentation to meet the needs of monitoring underground rock behaviour; as well as the manufacture and supply, worldwide, of specialist communications equipment for underground rescue and confined space working. See our Instrumentation page for more information.
