Abstract

This report gives an appreciation into the design and development of the ThunderBurst testing
frame undertaken as part of USQ’s research project.

ThunderBurst is a conceptual design for a driver-less machine used in underground mining to destroy large boulders following a designated blast without using explosive material. Russell Mineral Equipment Pty Ltd (RME) first started investigation into the feasibility of the project in 2002. This machine uses RME ThunderBolt hammer technology to impart a high-energy blow to a
column of water inside a rock.

The ThunderBolt test frame is designed to provide this high-energy system with a fixed location to
impact a water column and conduct the pressure wave analysis of the subsequent shock waves.
This consistent position will ensure the accurate calculation the pressure waves and energy values
through a column of water during its operation. On-going research project undertaken by RME to
increase understanding into future energy requirements of hydro-rock fracture will be achieved with
the development of this project. It is hoped that the preliminary research into the pressure wave
motion using the test frame will help develop the design of the ThunderBurst energy delivery
system and conclusions drawn from the project will form the foundation of continued development
of this product.
