Description

Technical Field

[0001] The present invention relates to the technical field of gold mining, and more particularly to a tunneling device and a tunneling method for gold mining. Background Art

[0002] Gold, as a vital strategic resource, holds a key position in the national economy. With the gradual depletion of shallow gold resources and the increasing depth of mining, the mining environment is becoming increasingly complex. Deep mining often faces complex geological conditions such as high ground pressure, high ground temperature, and high water pressure. These conditions, coupled with increased fractured rock mass, poor surrounding rock stability, and significant deformation, present numerous challenges to raise shaft construction and mining operations.

[0003] Prior art publication number CN118855460A discloses a coal mine excavation device comprising a machine body, a drive box, a transmission box, and a main drum. The drive box houses a driving motor, a rotating shaft, a through-tube, and an adjustment structure. The first end of the rotating shaft is connected to the output end of the driving motor, and the through-tube is disposed outside the rotating shaft and connected to the adjustment structure. The transmission box houses a transmission mechanism connected to the second end of the rotating shaft, and the transmission box housing is connected to the through-tube. The main drum is located on one side of the transmission box in an axial direction, and its drum housing is connected to the transmission box housing. The main drum is connected to the transmission mechanism so that power from the driving motor is sequentially transmitted to the main drum via the rotating shaft and the transmission mechanism. The adjustment structure drives the through-tube to rotate about its own axis, which in turn drives the transmission box housing to rotate about the axis of the through-tube, allowing the angle formed between the central axis of the main drum and the horizontal plane to be adjustable. This application addresses the problem of existing coal mine excavation devices having poor sidewall brushing performance on both sides of the roadway.

[0004] Although the device has many beneficial effects, the following problems still exist: Although the tunneling device can solve the problem of poor brushing effect of existing coal mine tunneling devices on both sides of the tunnel, if the heat generated during the tunneling process cannot be recovered, it will be directly dissipated into the environment, causing energy waste. Especially in deep mining, the increase in ground temperature causes the temperature of the tunneling working face to be too high, and additional refrigeration equipment is required to maintain the working environment, further increasing energy consumption.

[0012] Preferably, a semi-arc-shaped notch is provided on the outer surface of the inlet, and a connecting seat is fixedly connected to the bottom of the inlet. The connecting seat is arc-shaped, and a snap-in groove is provided inside the connecting seat.

[0016] A tunneling method for gold mining using a tunneling device comprises the following steps:

[0017] S1. After the device is started, the electric control box controls the operation of each cylinder and motor. By adjusting the extension and contraction of the first, second, third, and fourth cylinders, the posture of the device body can be flexibly adjusted to ensure the accurate excavation direction of the cutting head. The fourth cylinder pushes the rear support legs to expand, providing stable support for the device and ensuring stability during the excavation process. The turntable rotates under the drive of the third cylinder, driving the shovel and other excavation components to adjust to the appropriate angle;

[0019] S3. During the excavation process, the heat generated inside the device enters the box of the heat recovery component through the inlet. The first filter set at the inlet performs preliminary filtering on the incoming air to prevent large particles of impurities from entering the heat recovery system. The heat is exchanged with the spirally distributed heat recovery pipe in the box. The cooling medium flowing in the heat recovery pipe absorbs heat and the temperature rises. The heat exchange box and the heat recovery pipe are tightly connected, which further promotes heat transfer and improves heat exchange efficiency. The cooling water after absorbing heat flows into the cooling water tank through the water pipe and is recycled after cooling to achieve continuous heat recovery. During the heat exchange process, some impurities may enter the separation box with the air. The second filter in the separation box performs secondary filtering on the air to effectively intercept impurities. The second filter is slidably connected to the separation box through a slide slot for easy disassembly and cleaning. The magnetic connection between the second magnet and the first magnet ensures that the filter is firmly installed. The air after heat exchange and filtration is discharged from the box through the outlet, completing the entire heat recovery process.

[0020] S4. The two movable wheels rotatably connected on the outer surfaces of both sides of the device body realize the movement of the device through tracks to adapt to the walking needs of different terrains.

The fourth cylinder (8) pushes the rear support legs (7) to expand, providing a stable support force for the device, ensuring stability during the excavation process. The turntable (607) rotates under the drive of the third cylinder (606), driving the excavation components such as the shovel plate (603) to adjust to a suitable angle. S2, the first cylinder (601) drives the shovel plate (603) to move up and down, cooperating with the rotation of the turntable (607) to cut and crush the gold mine rock mass to achieve the tunneling function. The second cylinder (602) assists in adjusting the position and angle of the tunneling components through the connecting plate and other structures to adapt to the tunneling requirements under different geological conditions; S3. During the excavation process, the heat generated inside the device enters the box (901) of the heat recovery component (9) through the inlet (902). The first filter (908) provided at the inlet (902) performs preliminary filtration on the incoming air to prevent large particles of impurities from entering the heat recovery system. The heat is exchanged with the spirally distributed heat recovery pipe (909) in the box (901). The cooling medium flowing in the heat recovery pipe (909) absorbs the heat and the temperature rises. The heat exchange box (910) is tightly connected to the heat recovery pipe (909), further promoting heat transfer and improving heat exchange efficiency. The cooling water after absorbing the heat passes through the water pipe (91 1) Flowing into the cooling water tank (905), and being recycled after being cooled, the heat is continuously recovered. During the heat exchange process, some impurities may enter the separation box (912) along with the air. The second filter (914) in the separation box (912) performs secondary filtration on the air, effectively intercepting the impurities. The second filter (914) is slidably connected to the separation box (912) through the chute (915), making it easy to disassemble and clean. The magnetic connection between the second magnet (918) and the first magnet (916) ensures that the filter is firmly installed. The air after heat exchange and filtration is discharged from the box (901) through the outlet (903), completing the entire heat recovery process. S4. Two movable wheels (2) rotatably connected to the outer surfaces of both sides of the device body (1) realize the movement of the device through the crawler (3) to adapt to the walking requirements of different terrains. The rear support legs (7) are expanded and retracted under the drive of the fourth cylinder (8), providing stable support force for the device and ensuring stability and safety during the excavation process.
