Description

Technical Field

[0001] The present invention relates to the technical field of blasting devices and methods, and particularly relates to an automated device and method for an advanced pre-splitting rock-breaking device. Background Art

[0002] In the prior art, the problem of hard rock fragmentation often restricts the development of construction technologies and seriously delays the construction period. In current rock-breaking construction, the main method used is blasting-induced fracturing. The blasting-induced fracturing method has characteristics such as high efficiency and low cost, and is widely used in rock mass excavation in mining engineering, underground traffic engineering, water conservancy and hydropower engineering, etc. In addition, when using the blasting-induced fracturing method, in order to avoid over-excavation, under-excavation, and control the blasting contour line, dense holes are drilled at the excavation boundary and low-power explosives are used for advanced blasting pre-splitting.

[0003] The strong shock waves generated during the explosive blasting operation will cause disturbance and damage to the rock mass in the near zone, as well as vibration hazards to the rock mass, which will thus have a certain impact 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 at the same time achieve a relatively ideal rock-breaking effect, a new rock-breaking technology that uses high-energy gas expansion to do work to fracture the rock mass has emerged. In particular, the CO2 phase change expansion fracturing technology is receiving extensive attention in fields such as mine exploitation, tunnel excavation, and municipal transportation.

[0004] The high-energy gas fracturing technology is a technology that uses the shock waves and explosive gases generated by the combustion of gunpowder (explosives) in a short period of time to fracture the rock mass. At first, high explosives such as TNT were used to implement explosive fracturing of the reservoir, but it was gradually phased out due to the too large damage to the wellbore and formation by the explosion. Instead, the high-energy gas fracturing is implemented by using the deflagration of gunpowder (explosives) such as nitrocellulose. In recent years, a series of high-energy gunpowders with more stable deflagration, safer, and more efficient have emerged, such as thick nitro-methane explosives and liquid propellants. In principle, the CO2 phase change expansion fracturing device also belongs to a kind of high-energy gas fracturing technology, and was first developed by scientific research personnel in European and American countries. This device uses liquid CO2 as the medium, and encapsulates liquid CO2 and a heating tube (explosive substance) in a closed container. The heating tube is excited to generate a temperature above 800 °C within dozens of milliseconds, the pressure of the liquid CO2 increases sharply, and the high-pressure gas is rapidly released, causing the rock mass to crack or break. During the construction process of fracturing the rock mass by CO2 gas explosion, due to the premature triggering of the heating tube (Class II explosive) under accidental factors such as friction and static electricity, events such as the explosion or flying of the fracturing tube have occurred. However, whether it is the controlled blasting technology or the high-energy gas fracturing technology, currently, Class I and Class II civilian explosives are used to varying degrees (the heating agent used in the current CO2 phase change expansion fracturing technology belongs to Class II civilian explosives), and currently, these fracturing technologies are all manually operated, with low efficiency and without fundamentally solving the safety and impact disturbance problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automated device for the existing advanced pre-splitting rock-breaking technology, which realizes the automation of advanced pre-splitting rock-breaking and improves the safety and repeatability of advanced pre-splitting rock-breaking.

[0013] Preferably, the second telescopic arm includes a cylinder two. The cylinder two is perpendicular to the central axis of the stainless steel hollow cylinder body. A rack two is provided at the bottom of the cylinder two. The rack two is engaged with the gear of the 2# servo motor. The 2# servo motor drives the cylinder two to move left and right.

[0014] Further, the repeatable automatic electrical excitation device includes two symmetrically arranged Z-shaped conductive rods. One end has a wiring device on the outside and one end is inside the cylinder body. The inner end is provided with a telescopic metal contact. Wiring holes are symmetrically provided on the left and right sides of the stainless steel hollow cylinder body. The two Z-shaped conductive rods respectively pass through the wiring holes and are connected to the detonator. When the piston is fixed by the second telescopic arm, the two telescopic metal contacts respectively contact the two electrodes in the shaped charge. The two Z-shaped conductive rods are symmetrically arranged with respect to the above axis. A feed port is provided on the left side of the stainless steel hollow cylinder body.

[0016] Further, the automatic pressure relief device includes an inverted bursting disc storage box with an opening facing downwards arranged on the right side of the stainless steel hollow cylinder body. A spring plate is fixedly provided at the top of the inverted bursting disc storage box. A number of bursting discs are provided below the spring plate. A 3# cylinder body channel in the horizontal direction is provided at the bottom of the inverted bursting disc storage box. A hole four and a hole five are respectively provided on the left and right sides of the automatic pressure relief device.

[0017] The present invention also provides a tunneling method for an automation device of an advanced pre-splitting rock-breaking device, including the following steps:

[0018] In the initial state, the hydraulic cylinder, the first telescopic arm, the second telescopic arm, and the push rod are all in the retracted state, the shaped charge gripper is in the open state, the bursting disc is installed, and the outer end of the Z-shaped conductive rod is connected to the initiator.

[0019] Step 1: The shaped charge enters the device through the shaped charge channel. After being at the center of the shaped charge gripper, the small servo motor drives the shaped charge gripper to clamp the shaped charge, and the 1# servo motor drives the first telescopic arm to enter the cylinder through the 1# cylinder channel until the axis of the shaped charge is collinear with the central axis of the stainless steel hollow cylinder.

The small servo motor drives the shaped charge gripper to open, and the 1# servo motor drives the first telescopic arm to retract.

[0021] Step 3: The hydraulic cylinder continues to be pressurized until the through hole in the piston is connected to the 2# cylinder channel. The 2# servo motor drives the second telescopic arm to enter the 2# cylinder channel to fix the piston.

High-pressure fluid is injected from the feed port, the excitation device is excited, and the shaped charge and the high-pressure fluid react in the reaction chamber formed by the repeatable automatic electric excitation device and the automatic pressure relief device in the space of the stainless steel hollow cylinder.

[0023] Step 5: After the pressure in the reaction chamber reaches the critical value, the bursting disc ruptures, and the high-temperature and high-pressure fluid is instantly discharged to break the rock.
