Problems solved by technology
When mining shale gas in a mine, it is necessary to crack the underground rock formations. At present, people use crackers to crack the rock formations. Although the existing crackers can crack the rock formations, the cracking strength is not enough, making The extraction efficiency of shale gas is not high, and the energy utilization rate is not high, which brings inconvenience to users

The invention discloses a gas cracking device which comprises a main pipe, an energy dissipation device, an energy isolation release device, an energy charging electrode valve, an excitation device and a connecting component. Sealing devices are arranged on two sides of the main pipe. The device is reasonable in design and can be filled with various gases for fracturing a rock layer or cracking a coal bed, the gases are mixed with a small number of sand powder particles for the first time, cracking effects are better, duration time is longer, and energy use ratio is high. A plurality of devices can be connected and used for cracking ultra-deep holes, and the problems of unreliable circuits connected by a plurality of pipelines, insufficient energy supply and the like are solved. Pressure in the main pipe and pressure release are controlled by the energy isolation release device, so that the pressure and energy released by the cracking device are more accurate and controllable, and the controlled pressure is safer and more reliable. All circuit connections of the device are internal and totally closed, open flame is avoided in the whole operation process, and the device is safer to use in a mine with coal and gas burst.
Description
technical field [0001] The invention relates to the field of mine mining, in particular to a gas cracker. Background technique [0002] Our country is rich in overall resources, and there are various rich mineral resources underground. Minerals generally refer to all natural minerals or rock resources buried underground (or distributed on the surface, or weathered rocks, or rock deposits) that can be used by humans. According to the characteristics of minerals and their main uses, minerals are divided into energy minerals, Metallic minerals, non-metallic minerals and water gas minerals, shale gas is one of them. In order to exploit underground shale gas, people will build mines in resource areas, and mines are mines mined underground. When mining shale gas in a mine, it is necessary to crack the underground rock formations. At present, people use crackers to crack the rock formations. Although the existing crackers can crack the rock formations, the cracking strength is no...
