Experimental investigation of bench caving

  • A. É. Rozenplenter
Open-cut Mining


The caving process has a definite cycle with approximately constant parameters, other conditions (bench height, rock type, and composition), being equal. Collapse of the rock is preceded by the formation of cracks on the upper terrace and their relatively slow widening. This shows that the caving of underworked benches has its own particular laws. Extensive studies of these laws for varied bench heights, physical and mechanical rock properties and underworking methods will enable us to obtain a scientific basis for the use of the caving effect in working overburden benches. It is also necessary to study the conditions of landslide formation, so that this phenomenon can be used to work overburden benches.
