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-cracking rock breaking device and method.
Background
In the prior art, the hard rock crushing problem often restricts the development of construction technology, and severely slows down the construction period. The blasting fracturing method is mainly adopted in the 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, hydraulic and hydroelectric engineering and the like. In addition, when using the blasting fracturing method, in order to avoid overexcavation, underexcavation and control of the contour line of blasting, dense holes are drilled at the excavation boundary, and advanced blasting pre-fracturing is performed by using low-power explosive.
The strong shock wave generated in the explosive blasting operation process can cause disturbance and damage of the near-zone rock mass and vibration hazard of the rock mass, so that certain influence can be caused 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 achieve the ideal rock breaking effect, the novel rock breaking technology for breaking the rock mass by using the high-energy gas expansion work, in particular to CO 2 The phase-change expansion fracturing technology is receiving wide attention in the fields of mining, tunneling, municipal transportation and the like.
The high-energy gas fracturing technology is to utilize shock waves and explosive gas generated by the combustion of fire (explosive) drugs in a short time to fracture the rock mass. Explosive fracturing is carried out on a reservoir by adopting high explosive such as TNT (TNT) at first, but the explosion is too large to destroy a shaft and a stratum and is gradually eliminated, and the detonation of a fire (explosive) such as nitrocotton is used for carrying out high-energy gas fracturing instead. In recent years, a series of high-energy gunpowder with more stable, safer and more efficient deflagration, such as thick nitromethane explosive, liquid propellant and the like, also appear. In principle, CO 2 The phase-change expansion fracturing device also belongs to one of the high-energy gas fracturing technologies, and is researched and developed by European and American national scientific researchers at the earliest. The device utilizes liquid CO 2 For the medium, liquid CO 2 And a heat generating tube (explosive material) is enclosed in a closed container. Exciting the heating tube to generate high temperature of 800 ℃ within tens of milliseconds, and liquid CO 2 The pressure increases sharply and the high pressure gas releases rapidly, causing the rock mass to crack or break. In CO 2 In the gas explosion fracturing rock mass construction process, a fracturing pipe explosion or a pipe flying event occurs because a heating pipe (II-class explosives) is triggered in advance under the action of accidental factors such as friction, static electricity and the like. However, the process is not limited to the above-described process,whether the blasting technology or the high-energy gas fracturing technology is controlled, the current method is used for I, II type civil explosives (the heating drugs used by the current carbon dioxide phase-change expansion fracturing technology belong to II type civil explosives) to different degrees, and the current method is manually operated when the fracturing technologies are used, so that the problems of safety and impact disturbance are not fundamentally solved while the efficiency is low.
