A high-voltage pulse-focused jet generating system and its application method

Abstract

The invention discloses a high-voltage pulse energy-gathering jet generating system and its application method. The system includes a high-pressure pulse energy-gathering jet generator, a gas supply system, a fluid supply system and a hydraulic oil supply system. The high-voltage pulse energy-gathering generator includes a rear End cover, pressure cylinder, piston, sliding sleeve, piston sleeve, energy-concentrating nozzle and front end cover, this system can adjust the delivery pressure of the air source supply system according to different rock hardness conditions, and can form the maximum pressure without increasing power consumption The high-pressure pulsed energy-concentrating jet that is several times stronger than the rock can achieve efficient crushing of hard rock formations and improve the efficiency of hard rock roadway excavation.

Description

technical field [0001] The invention relates to the field of high-voltage pulsed energy-focused jets, in particular to a high-voltage pulsed energy-focused jet generating system and a method for using the same. Background technique [0002] China is still the world's largest energy consumer, accounting for 24% of global energy consumption and 34% of global energy consumption growth. Coal accounts for 58% of my country's primary energy structure. , coal will still be the most important basic energy source in my country, and with the continuous mining of coal resources in my country, the slow driving speed of hard rock roadways and the imbalance of mining ratio have become the key problems restricting the development of my country's coal industry. [0003] At present, domestic rock roadway excavation mainly adopts drill-and-blast method and fully-mechanized excavation method. The specific energy consumption per unit is large, the tool wear is serious, the vibration of the mach...

Problems solved by technology

[0003] At present, domestic rock roadway excavation mainly adopts drill-and-blast method and fully-mechanized excavation method. The specific energy consumption per unit is large, the tool wear is serious, the body vibration is too large, and the reliability of the machine is weak. Neither of the two traditional construction techniques can achieve efficient tunneling in hard rock roadways.
