[0040] Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] Figure 1 It is a schematic flow chart of a reverse construction method for a high-angle blind inclined shaft according to an embodiment of the present invention.

[0042] like Figure 1 As shown, the reverse construction method of a high-angle blind inclined shaft provided by the present invention includes steps S110 to S140.

[0043] S110, a scavenging winch is arranged at the top of the inclined shaft, and the slag is loaded into a side-discharging mine car located at the slag loading position by using the scavenging winch and the electric rock rake. A safety door is arranged at the wellhead of the inclined shaft. Along the setting direction of the side-discharging mine car, the safety door is arranged in front of the mining hoist. The rock loading range of the scavenging winch and the electric rock rake is 115 meters.

[0044] S120. The side-discharging mine car filled with rock slag is transported downward to the slag chute along the track set in the inclined shaft by a mining hoist arranged at the bottom of the inclined shaft with a steel wire rope. The hoisting center line of the mining hoist is arranged on the right side of the tunnel, and the hoist has a rope deviation angle of 1°30" at the vertical wheel group setting; that is, the rope deviation angle of 1°30" of the hoist wire rope required by the specification is ensured at the vertical wheel group setting; and the steel wire rope of the mining hoist adopts a bottom-out rope method, wherein the number of winding layers is less than 3. The number of the horizontal wheel groups arranged is greater than or equal to 2 groups.

[0045] S130, after the side-unloading mine car is automatically tipped over by the unloading curved rail to unload the slag, the side-unloading mine car is automatically reset by the unloading curved rail; wherein the slag unloading chute is arranged at the lower part of the inclined shaft. Along the traveling direction of the unloading mine car, the unloading curved rail is arranged on the right side of the track.

[0046] S140, using the reverse lifting guide system to change the traction direction of the wire rope, the unloaded side-dumping mine car is lifted upward along the track set in the inclined shaft to the loading position for the next round of slag loading.

[0047] The reverse lifting guide system includes a horizontal wheel group for providing support for the wire rope and guiding the wire rope to change its traveling direction and a vertical guide wheel group for ensuring that the wire rope derived from the self-elevator drum meets the specific rope deflection requirements; the horizontal wheel group is above the track of the loading position, and the wheel groove of the guide wheel of the horizontal wheel group is precisely aligned with the center line of the wire rope; wherein the vertical guide wheel group is set at a distance of 29m from the hoist; the rope outlet point of the vertical guide wheel group coincides with the center line of the hoist drum. In a specific embodiment, the reverse lifting guide system includes the two sets of horizontal wheel groups for supporting and changing the direction of the return rope in the horizontal direction and a set of vertical guide wheel groups for ensuring the rope deflection of the wire rope from the hoist drum; wherein the vertical guide wheel group is set at a distance of 29m from the hoist; the horizontal wheel group is set above the track of the loading position, and the wheel groove of the horizontal wheel group is aligned with the center line of the wire rope; the rope outlet point of the vertical guide wheel group coincides with the center line of the hoist drum.

[0049] Example 2

[0050] Figure 2-Figure 5 The various structures of the reverse construction device for high-angle blind inclined shaft are described in general. Specifically, Figure 2 It is a structural schematic diagram of a reverse construction device for a high-angle blind inclined shaft according to an embodiment of the present invention. Figure 3 Schematic diagram of the arrangement of a mining hoist according to an embodiment of the present invention. Figure 4 It is a schematic diagram of the layout of a slag chute according to an embodiment of the present invention. Figure 5 is a schematic structural diagram of a blocking system according to an embodiment of the present invention.

[0051] The present invention also protects a construction device for a reverse construction method of a large-angle blind inclined well, which is used to implement the reverse construction method of a large-angle blind inclined well, such as Figure 2 As shown, the device includes a scraper winch 1 arranged at the top of the inclined shaft 6, an electric rock scraper 2 is relay-connected to the scraper winch 1, and a slag loading position is provided at the end of the electric rock scraper 2; a slag unloading chute 5 is provided at the lower part of the inclined shaft 6; a track 12 for transporting side-discharge type mine cars is provided between the slag loading position and the slag unloading chute 5; an unloading curved track 13 for automatic tipping and automatic resetting of the carriage of the side-discharge type mine car 4 is provided at the slag unloading chute 5; a mining hoist 7 is provided at the bottom of the inclined shaft 6, and the mining hoist 7 is connected to the side-discharge type mine car 4 through a wire rope; a reverse lifting guide system 3 for changing the traction direction of the wire rope is provided above the slag loading position.

[0052] In the specific implementation process, a P60-B electric rock scraper has a rock loading distance of 60m, and the working face is relayed by a 2JP-30 scraper winch with a rock loading distance of 55m. The total rock loading range of the slag loading system is 115m. When the reverse guide system does not need to move forward, the free excavation project length is 115m, which effectively reduces the number and time of forward slag loading terminals and improves construction efficiency. The monthly excavation footage is not less than 70m, which is much higher than the construction efficiency of 40m per month of other methods. The universal JTP-1.6x1.5P mining hoist is used as the transportation power system, equipped with a 2.5m 3The mine car has lengthened the P60-B electric rock scraper through technical transformation, and at the same time relayed the 2JP-30 scraper winch to load the rock. It uses traditional and low-cost equipment for optimal combination, fully utilizes the equipment performance, and greatly improves the efficiency of small equipment use.

[0053] The reverse lifting guide system includes two groups of horizontal wheel groups for supporting and changing the direction of the return rope in the horizontal direction and one group of vertical guide wheel groups for ensuring the rope deflection angle of the wire rope coming out from the hoist drum; wherein, the vertical guide wheel group is arranged at a distance of 29m from the hoist; the horizontal wheel group is arranged above the loading position track 12, and the wheel groove of the horizontal wheel group is aligned with the center line of the wire rope; the rope outlet point of the vertical guide wheel group coincides with the center line of the hoist drum. A semi-enclosed protective shell is arranged on the periphery of the horizontal wheel of the horizontal wheel group. Reverse lifting by means of the horizontal guide wheel located on the track 12 eliminates the risk and hidden danger of falling off and rope shaking caused by rock changes of the ordinary top plate vertical fixed guide wheel, reduces the risk of overturning and falling off the track caused by excessive vertical force of the mine car, and the semi-enclosed guide wheel better protects the wire rope and improves the safety of the entire inclined shaft upward transportation.

[0054] In the specific implementation process, in the mine hoisting system, changing the traction direction of the wire rope is one of the key technologies to realize the up and down transportation of the mine car in the inclined shaft. The setting of two sets of φ600mm horizontal semi-enclosed protective horizontal wheels and one set of φ600mm vertical guide rollers needs to be carefully designed to ensure the effective guidance and direction change of the wire rope. The setting of the horizontal semi-enclosed protective horizontal wheels, the main function of these two sets of horizontal wheels is to maintain the stability and direction change of the wire rope in the horizontal direction when the mine car goes up and down the inclined shaft. As an implementation method, the horizontal wheel should be set at a position close to the top of the inclined shaft, so that it can provide stable guidance for the wire rope when the mine car goes up and down the inclined shaft. It should be noted that the wheel groove of the horizontal wheel should be aligned with the center line of the wire rope to ensure that the wire rope remains centered when passing through and reduce wear. Due to the semi-enclosed protective design, it should be ensured that the protective shell can effectively prevent debris from entering the wheel groove, while allowing necessary maintenance and inspection of the wheel. In addition, the vertical guide roller is used to change the traction angle of the wire rope. It is set at a distance of 29m from the hoist to ensure that the rope deviation angle of 1°30" required by the hoist wire rope specification is met at the vertical wheel assembly. The vertical guide roller should be able to adjust the angle to accommodate fine-tuning of the wire rope outlet angle, which may require an adjustable bracket or base. Due to the tension when the wire rope changes direction, the vertical guide roller must be strong enough to withstand high loads and wear.

[0055] Through this setting, two sets of horizontal semi-enclosed protective horizontal wheels and a set of vertical guide rollers work together to ensure that the traction direction of the wire rope in the inclined shaft can be changed smoothly, thereby achieving safe and efficient transportation of the mine car. This setting is crucial to maintaining the stability and safety of the mine hoisting system.

[0056] The 0.6-meter-diameter reverse wheel, frame and steel are connected by 8.8-grade high-strength bolts and welded to ensure the stability and safety of the structure. 250mm*20mm steel and 24kg / m rails, as well as 150-type sleepers, are standard materials for building mine tracks and support systems. φ36 round steel is used as ground anchors, and two sets of HW-250MM steel are used to build the support structure of the track. The ground anchors are used to fix the structure, and the track and sleepers are the basis for the operation of the mine car. The down track is equipped with φ160mm rollers, which are used to support and guide the mine car on the track.

[0057] like Figure 3 As shown, the drum centerline of the mine hoist 7 should be aligned with the right side of the roadway to meet the specific rope deflection angle requirements. For example, when the mine hoist is arranged horizontally, the hoist centerline should be placed on the right side of the roadway to meet the rope deflection angle requirement of 1°30" at 29m. Ensure that the drum centerline is positioned correctly to facilitate proper guidance and tension distribution of the wire rope.

[0058] Among them, a safety door 11 is arranged at the wellhead of the inclined shaft. Specifically, a steel anti-collision safety door should be arranged in front of the mine hoist to prevent the wire rope from touching the tunnel wall when swinging, causing damage to the wire rope. That is, along the setting direction of the side-unloading mine car, the safety door 11 is arranged in front of the mine hoist. The safety door (mine hoisting safety door) is an openable door to prevent vehicles, materials, and personnel from falling into the well. The safety door should have a certain strength to prevent the inertial movement of the mine car from sliding into the shaft. The specifications and models of the safety door depend on the tonnage of the cage and the mine car, the number and number of layers of the cage, and the number of mine cars accommodated in each layer of the cage. In order to keep the safety door in a closed state, some mines install a limit electrical switch on the safety door beam, which is electrically interlocked with the hoist signal. If the safety door is not closed, the mine hoist cannot be started.

[0059] In the specific implementation process, the design of the tunnel needs to consider the safety and efficiency of transportation, and the support material loading track should be stable to ensure the safe transportation of materials. The foundation excavation boundary should be comprehensively considered based on the size and number of lifting containers, the size of ladder rooms, cables, water pipes, gas pipes, etc. and the necessary safety spacing, which will be determined by the design. The shaft should adopt full-section support measures, and reinforced concrete pouring support should be used within 20 meters from the ground and in the broken areas passed. The wire rope of the mining hoist adopts the bottom rope method, and the number of winding layers is less than three. This is to reduce the wear of the wire rope and improve the lifting efficiency.

[0060] like Figure 4 As shown, in the specific implementation process, the side-discharging mining car 4 is 2.5m 3 Mine car. During the journey, the unloading curved rail 13 is used to realize the automatic tipping and unloading of the car and automatic resetting. This mine car has an advanced structure and is made of special steel, which is sturdy and durable. The size of the chute is 3 meters × 1.5 meters × 5.25 meters. It is used for unloading ore and waste rock and is an important part of the unloading system. The specification of the track is 900mm. This is the track on which the mine car runs, ensuring the stable operation of the mine car and the smooth transportation of materials. The unloading curved rail 13 is placed on the right side and unloaded on the left side along the forward direction. This design enables the mine car to be automatically unloaded when passing through the unloading curved rail. The left step on the uphill side is 0.8 meters and is processed and installed with steel plates. This is to provide a stable step for the safe operation of personnel and equipment.

[0061] In summary, the unloading system includes key components such as side-unloading mine cars, slag chutes, transport tracks, unloading curved tracks, steps, etc. These components work together to achieve safe and efficient unloading of ore and waste rock. Each component has its specific specifications and functions to ensure the smooth progress of the entire unloading process.

[0062] like Figure 5 As shown, as an improvement of this embodiment, a first blocking member 8, a second blocking member 8, a third blocking member 9 for blocking the unloading mine car and a control system 10 for controlling the first blocking member 8, the second blocking member 8, and the third blocking member 9 are provided in the inclined shaft 6; the first blocking member and the second blocking member are buffers provided on the track; the third blocking member is a vehicle barrier provided above the track. The control system can be an electric retractor, and the lifting wire rope of the electric retractor passes through the fixed pulley provided at the top and is respectively connected to the first blocking member 8, the second blocking member 8, and the third blocking member 9. In other words, as long as the control system 10 is triggered, the first blocking member 8, the second blocking member 8, and the third blocking member 9 all perform the falling blocking operation driven by the lowering of the lifting wire rope 14.

[0063] Generally speaking, at the top of the inclined shaft, a mine-raking winch is installed to assist the electric rock-raking machine to collect the crushed stone and rock slag. The electric rock-raking machine is arranged in the middle and upper part of the inclined shaft, responsible for collecting the rock slag and transporting it to the side-dumping mine car in the loading area. The side-dumping mine car filled with rock slag is transported down the inclined shaft by the mine hoist located at the bottom of the inclined shaft. During this process, the mine car uses the inclination angle of the inclined shaft and the power of the hoist to safely transport the rock slag to the slag unloading area at the bottom of the inclined shaft. After reaching the bottom of the inclined shaft, the side-dumping mine car operates through a specific unloading curved track to unload the rock slag into the slag unloading chute. The slag unloading chute is located at the bottom of the inclined shaft and is used to collect and guide the rock slag to the designated unloading location. After unloading is completed, the empty side-dumping mine car is lifted back to the loading position at the top of the inclined shaft through the reverse lifting and guiding system. This system allows the mine car to efficiently return to the loading area after unloading, ready for the next round of rock slag loading.

[0064] In summary, the reverse construction device and method of a high-angle blind inclined shaft of the present invention is achieved by arranging a ore-raking winch and an electric rock-raking machine at the top of the inclined shaft, a slag chute at the bottom, and a mining hoist at the bottom to pull the side-discharging mine car through a wire rope; the reverse hoisting guide system is used to change the traction direction of the wire rope, so that the side-discharging mine car can quickly travel back and forth between the loading position and the slag chute, thereby improving the flexibility and continuity of the construction and the transportation efficiency of the rock slag. The high efficiency, high safety and low cost of the reverse construction of a high-angle and long-distance blind inclined shaft are achieved, and it has a technical effect of important practical value for the construction of deep mines. The present invention is suitable for the scenario of simultaneous construction of multi-stage inclined shafts, which greatly saves infrastructure investment and shortens construction period, bringing economic benefits to construction projects.
