Abstract

The present invention provides a rock-breaking device using high-frequency electric pulses to assist impacting and its construction technology. The high-frequency electric pulse is used in the process of mechanical rock breaking to form a strong impact force, which can specifically solve the problems of ordinary rock-breaking electric drill bits such as easy wear, high impact, large pollution, high risk factor, and difficult fine operation, etc., and the structure is simple and the material Easy to obtain, easy to operate, fast construction, greatly saving test cost and cycle, widely used in tunnel engineering, reservoir bank slope engineering, water conservancy engineering, coal mine tunnel and foundation pit engineering, has extensive engineering practical significance and application prospects .

Description

technical field [0001] The invention relates to a rock-breaking device utilizing high-frequency electric pulse assisted impact and its construction technology. The rock-breaking device uses high-frequency electric pulse jet to assist the drill bit to generate huge impact force, and integrates ultra-high-frequency electric pulse jet into mechanical impact rock-breaking In the process, it is widely used in tunnel engineering, reservoir bank slope engineering, water conservancy engineering, coal mine tunnel and foundation pit engineering. Background technique [0002] At present, rock crushing is a process of separating part of the rock mass from the parent body and breaking it into rock blocks during mining operations. There are mainly four methods in the prior art: explosive crushing, mechanical crushing, water jet crushing and thermal crushing. Among them, explosive fragmentation uses the huge energy released by explosives or other explosives to crush rocks. Currently, it is...
