Description
Technical Field
The invention relates to the technical field of blasting devices and methods, in particular to a high-temperature high-pressure fluid hole internal circulation impact energy-release advanced pre-splitting rock breaking device and method.
Background
In the prior art, the development of construction technology is often restricted by the problem of hard rock crushing, and the construction period is seriously slowed down. The blasting fracturing method is mainly adopted in rock breaking construction at present, has the characteristics of high efficiency, low cost and the like, and is widely applied to rock excavation of mining engineering, underground traffic engineering, water conservancy and hydropower engineering and the like. In addition, when the blasting cracking method is used, in order to avoid contour lines of overbreak, underexcavation and controlled blasting, dense holes are drilled at the excavation boundary, and low-power explosives are used for advanced blasting pre-cracking.
The strong shock wave generated in the explosive blasting operation process can cause the disturbance and damage of near-zone rock mass and the vibration damage of the rock mass, thereby causing certain influence on the stability of the engineering rock mass and the safety of the surrounding environment. In order to improve the operation safety, reduce the strong impact disturbance and simultaneously achieve a more ideal rock breaking effect, a novel rock breaking technology of fracturing a rock body by utilizing high-energy gas expansion work, in particular CO is produced2The phase change expansion cracking technology is receiving wide attention in the fields of mining, tunnel excavation, municipal transportation and the like.
The high-energy gas fracturing technology is a method for fracturing rock mass by using shock wave and explosive gas generated by burning fire (explosive) in a short time. The reservoir is initially fractured by explosion by high explosive such as TNT, but the high explosive is gradually eliminated because the explosion damages the shaft and the stratum, and instead, the high-energy gas fracturing is performed by deflagration of explosive such as nitrocotton. In recent years, a series of high-energy gunpowder with more stable deflagration, safer detonation and higher efficiency, such as a thick nitromethane explosive, a liquid propellant and the like, also appear. In principle, CO2The phase change expansion cracking device also belongs to one of high-energy gas fracturing technologies, and is researched and developed by scientific research personnel in Europe and America at the earliest. ThePlant using liquid CO2Using liquid CO as medium2And a heating tube (explosive substance) are enclosed in a closed container. The heating tube is excited to generate high-temperature and liquid CO of over 800 ℃ within tens of milliseconds2The pressure is increased sharply, and high-pressure gas is released rapidly, causing the rock to crack or break. In CO2In the construction process of gas explosion cracking rock mass, as the heating tube (II type explosive) is triggered in advance under the action of accidental factors such as friction, static electricity and the like, the tube explosion or tube flying event of the cracking tube occurs. However, both the controlled blasting technology and the high-energy gas fracturing technology are currently used for I, II-type civil explosives (the heating powder used in the current carbon dioxide phase change expansion fracturing technology belongs to the II-type civil explosives), and the current fracturing technologies are all operated manually, so that the problems of safety and impact disturbance are not fundamentally solved while the efficiency is low.
