Abstract:
Dynamic impact test facilities are widely accepted for the testing and qualification of ground support systems intended for use in dynamic ground conditions, namely seismicity and rockbursting. As more underground mining operations target extraction of ore in higher rock stress environments, the demand for dynamic ground support continues to increase. It is therefore important that designers and manufacturers of ground support are capable of qualifying support systems under extreme loading conditions. To support industry requirements, Jennmar has designed and commissioned a direct impact dynamic test facility (the ‘DIT105Z’) which is capable of testing support elements with high energy impulse of up to 105 kJ in a single impact. The DIT105Z is capable of conducting dynamic tests with a quick turn-around and processing of data, allowing for agile research and development and product verification. Over the past 2 years, several new dynamic products have been developed and tested on the DIT105Z and these products are now implemented at a number of mines globally. This paper presents the capabilities of the DIT105Z and the results of a number of dynamic testing campaigns.
