High-prequency electrothermal rock breaking

Soviet Mining Science, 1968
1. Rocks of the second and fourth groups [above] are those most favorable for high-frequency electrothermal breakage. 2. To break rocks of the third group, it is necessary to build a plant with parameters enabling the generator to be matched with the load. 3.

Rock Recognition Using Stereo Vision for Large Rock Breaking Operation

2013
At the work front in a quarry, many large rocks are generated by rock blasting. Since some of these rocks are too large to be fed into a rock crusher machine, a hydraulic breaker is used to break the oversized rocks into suitable sizes. The purpose of this study is an automation of rock breaking operation in working front of an open-pit quarry. In this
