Hydrothermal rock breaking cracking device, detonating network and directional cutting method thereof

Abstract

The invention discloses a hydrothermal rock breaking cracking device, a detonating network and a directional cutting method thereof, and belongs to the field of mine mechanical engineering. The devicecomprises a directional cracker (2). The directional cracker (2) contains an ion water solution (11). The directional cracker (2) is provided with an inner container heat conducting pipe (3). A weakgap (2-1) is formed in the lower middle end of the directional cracker (2). The directional cutting method comprises the following steps that S1, water is injected into hydrothermal rock breaking devices; S2, hydrothermal rock breaking devices are in series-parallel connection; S3, hole forming, orienteering and hole sealing are performed; S4, the detonating network is connected, and the connectivity is detected; S5, security alert is given, and detonation is performed; S6, after one-time directional cutting operation is completed, the steps 1-5 are executed repeatedly, and circulation at thenext stage is started. Hydrothermal rock breaking cracking is adopted for replacing carbon dioxide gas explosion cracking, potential safety hazards in the storage, transporting and using processes aregreatly reduced, meanwhile, vibration disturbance and noise can further be lowered, and the device is particularly applicable to some specific environments where intense vibration and noise are forbidden.

Description

technical field [0001] The invention belongs to the field of mining machinery engineering, and in particular relates to a hydrothermal rock-breaking fracturing device, an initiating network and a directional cutting method thereof. Background technique [0002] In municipal transportation projects such as mining and stone mining, excavation of foundation pits, construction of tunnels and underground spaces, safe blasting and demolition of stubborn rocks / solitary rocks, and dredging of pipelines and other blockages, it is often necessary to excavate rock mass. In order to ensure the safety of surrounding structures and personnel, and reduce rock-breaking vibration and noise, CO 2 Gas explosion technology is being widely concerned in mining, tunneling, municipal transportation and other fields. [0003] However, there are three potential safety hazards in traditional carbon dioxide gas explosion technology. 1) The filling, storage and transportation of liquid carbon dioxide i...

Problems solved by technology

[0003] However, there are three potential safety hazards in traditional carbon dioxide gas explosion technology. 1) The filling, storage and transportation of liquid carbon dioxide involve high-pressure containers, which are prone to explosion risks; 2) carbon dioxide gas explosion requires the use of flammable and explosive materials. 3) After the carbon dioxide gas explosion device is filled with liquid carbon dioxide, it is easy to generate high pressure. The explosive type of fever medicine is directly placed in the high-pressure liquid carbon dioxide and directly contacted. Gas explosion device presents a risk of explosion
