Abstract

The invention discloses a mechanical device for generating plasma blasting rock with a liquid-electric effect. The mechanical device comprises a device body. The device body comprises a first casing pipe, a plasma generating part and a pressing part. The first casing pipe is provided with a sealing part used for sealing a drill hole drilled in the rock blasting process. The pressing part is used for pressing the sealing part so as to make the sealing part seal the drill hole. The plasma generating part is at least partially located inside the first casing pipe. An opening allowing the plasma generating part to release energy is formed in the first casing pipe and further located in the lower end of the sealing part. According to the mechanical device, the sealing part is used for sealing the drill hole drilled in the rock blasting process, and therefore the blasting energy can be sealed into the drill hole and be further concentrated to rock blasting, and the hard rock like granite canbe blasted. By adoption of the device, a non-explosive rock blasting method can be available.

Description

technical field [0001] The invention relates to the technical field of rock crushing, in particular to a mechanical device for blasting rocks with plasma generated by hydroelectric effect. Background technique [0002] Plasma rock crushing technology is an emerging high-efficiency rock crushing method at home and abroad. Plasma is generated by discharging at the electrode through high-voltage pulses, and the dielectric is crushed in the drill hole under the action of high temperature and high pressure. The force produced by the electric explosion method is the longitudinal tensile stress on the rock, the crushing effect is better, there is no pollution and flying stones in the rock breaking process, the energy consumption is small, and the noise and danger are low. [0003] South Korea, Russia, the United States and other countries have carried out research work on plasma rock breaking technology, and some plasma rock breaking equipment has been used in engineering. The spa...
