Rock breaking device for auxiliary impacting through high-frequency electric pulses and construction technology of rock breaking device

Abstract

The invention provides a rock breaking device for auxiliary impacting through high-frequency electric pulses and a construction technology of the rock breaking device. A high-frequency electric pulsedevice is used for rock splitting engineering taking schist as priority, the high-frequency electric pulses are used in the mechanical rock breaking process in the direction of the rock schistosity toform strong impact force, particularly, the problems that an ordinary rock breaking electric drilling bit is prone to being abraded, large in impact performance, heavy in pollution, high in danger coefficient, not prone to being finely operated and the like can be solved, the structure is simple, materials are easy to obtain, operation is easy, construction is rapid, the test cost is saved greatly, the test period is shortened greatly, and the rock breaking device is widely suitable for tunnel engineering, reservoir bank slope engineering, hydraulic engineering and coal mining mine adit and foundation pit engineering, and has wide engineering practice 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...
