Mining Testing Services

We offer a variety of testing services related to underground excavation support in the fields of rock and support system testing.

Our testing services include the following (these titles are hyperlinked to the text below):

 



Rock Bolt Integrity Testing (in situ)

A rock/cable bolt integrity testing system has been developed which uses a tuneable radio frequency (RF) source. The equipment is clipped to the bolt/cable and is therefore quick and simple to use. The RF system can provide information on the length of the installed bolt/cable and can be used to detect broken bolts/cables.

Support Load Measurement & Pulltesting

We offer a comprehensive strain gauge installation and monitoring service for steel supports, concrete linings, rockbolts and long tendons, using vibrating wire and resistance gauges. Rock and soil extensometry can be undertaken using sonic, resistance wire or potentiometric devices. In mining and other applications, we offer in-situ reinforcement system testing for bond strength using pull tests to industry standards.

Rock Testing

Our company resources and related technical expertise allow a complete rock testing service to ISRM standards encompassing core logging, sample preparation and determination of a range of rock properties. Key points:

  • Company geologists available for core logging.
  • Sample preparation for a wide variety of rock types and sample sizes.
  • Routine testing for Uniaxial Compressive Strength, Young's Modulus and Poisson's Ratio.
  • Specialist tests include Multistage Triaxial Testing with confining pressure to 70MPa with full reporting of peak and residual strength envelopes.
  • Interpretation of results as input parameters for computer modelling of excavations.

Support System Testing

We offer an integrated service for laboratory testing of support systems and associated items for mining and civil engineering purposes. Test programmes can be planned to confirm the suitability of a support system. Unbiased advice is offered on optimum support/reinforcement system design. A full range of mechanical tests is available on support/reinforcement elements. Precise laboratory pull testing to measure system bond strength in a range of rock types can be undertaken. Other test services include double embedment and other tests for reinforcement systems to BS7861, metallurgical investigations and laboratory rock drilling tests.
