Cavitation mechanisms in the front chamber of a dual-chamber-controlled hydraulic rock drill

The coupling between the high-frequency reciprocating motion of the impact piston and the transient internal flow field in a hydraulic rock drill constitutes the dynamic origin of cavitation in the system. To reveal the mechanism of cavitation evolution in the front chamber, this study focused on a dual-chamber-control...

Stress-path diagnosis of coal-roof damage in conglomerate-bearing open-pit bench blasting

Near-seam open-pit bench blasting in conglomerate-bearing overburden must break the rock mass while limiting coal-roof damage. Peak stress is often used as a screening variable, but it cannot describe the pressure-dependent response of coal. This study treats coal-roof damage as a stress-path problem using a two-dime...
