Thermal-Mechanical Fragmentation of Hard Rock - Field Tests
As with explosive energy, experimentation has shown that heat energy is much more effective in fracturing rock when it is applied internally. Creation of internal thermal stress fields results in controlled fracture of rock in place when proper displacement relief is provided. Fracture is exploited and block removal accomplished with mechanical rock splitters. Experimentation is supported by theoretical analysis and finite element calculations. The characteristics of the technique are favorable for application, as are the results of cost and systems analysis.
