电能转换法已经广泛地用于发展新的岩石破碎工艺。在近十年内,美国、苏联、荷兰、日本、德国和英国已进行了研究。从根本上讲,通过内部或外部的换能机械,能够实现岩石的电破碎。要使岩石内部产生应力就必须将电能送进岩石。电功率可转化为电 Energy conversion methods have been widely used to develop new rock crushing processes. In the past ten years, the United States, the Soviet Union, the Netherlands, Japan, Germany and the United Kingdom have conducted research. Fundamentally, electric rock fragmentation can be achieved through internal or external transducing machinery. To make the rock internal stress must be sent to the rock energy. Electric power can be converted into electricity
