Description

Technical Field

[0001] This utility model belongs to the field of coal mine production, and in particular relates to a system that can both increase the amount of gangue transported and expand the area of ​​gangue dumping. Background Technology

[0002] Coal gangue is a solid waste generated during coal mining and washing processes. It includes gangue from tunnel excavation, gangue extracted from the roof, floor, and interlayers during mining, and gangue removed during coal washing. Due to the large volume of coal gangue generated, effective management and disposal of this waste has become a significant issue.

[0003] Coal gangue disposal capacity refers to the ability of a coal mine to process and discharge coal gangue within a certain period of time. The type and performance of the disposal equipment directly affect the disposal capacity. In addition, effective management and planning are key to improving the disposal capacity. For example, by optimizing the disposal process, planning auxiliary roadways, and improving the disposal equipment, an efficient disposal system can be formed.

[0004] The average daily output of coal gangue underground is influenced by various factors, including tunnel excavation speed, daily cage hoisting frequency, geological conditions, mining technology, and management level. There is a close relationship between the capacity of the gangue removal system and the average daily output of coal gangue underground. An efficient gangue removal system can significantly improve the mining efficiency of coal mines and reduce production stoppages caused by poor gangue removal. Therefore, the design and optimization of the gangue removal system is crucial for the safe production and sustainable development of coal mines. However, due to advancements in technology and faster tunnel excavation speeds, the capacity of existing gangue transportation and unloading systems can no longer meet the rapid pace of gangue production during underground excavation.

[0005] In the current waste rock disposal system, the fixed mining cars can only discharge the waste rock to one side of the unloading platform, which causes the accumulation height of the waste rock in the dumping area to continuously increase. This prevents the waste rock dumping area from being effectively expanded and hinders the completion of subsequent waste rock dumping. Utility Model Content

[0006] The purpose of this invention is to provide a system that can both increase the amount of gangue transported and expand the area of ​​gangue dumping, in order to solve the problems that the existing gangue transport and unloading system cannot meet the gangue production speed of underground tunneling, and that the gangue dumping area is too small to hinder gangue dumping.

[0007] This utility model adopts the following technical solution: a system that can both increase the amount of gangue transported and expand the gangue dumping area, comprising:

[0008] The first pair of heavy-duty tracks are laid on the unloading platform above the gangue dumping area via trusses;

[0009] The second pair of heavy-duty car tracks are laid on the unloading platform above the gangue dumping area via trusses and are set parallel to the first pair of heavy-duty car tracks;

[0010] A single-sided curved rail side-discharge mine car travels on the first pair of heavy-duty rails and is used to pull gangue to the unloading platform and dump the gangue into the gangue dumping area.

[0011] The bottom-side unloading car travels on the second pair of heavy-duty car tracks and is used to pull the gangue to the unloading platform and dump the gangue into the gangue dumping area;

[0012] The unloading platform is rectangular or square in shape;

[0013] Among them, the single-sided curved rail side-discharge mine car is used to dump gangue to the first dumping side of the unloading platform, and the bottom-side unloading mine car is used to dump gangue to the second dumping side of the unloading platform, which can both increase the discharge of gangue and reduce the accumulation height of gangue in the dumping area; the first dumping side and the second dumping side of the unloading platform are adjacent.

[0014] Furthermore, the junction of the first pair of loaded car tracks and the unloading platform is connected to the second pair of loaded car tracks via the third pair of tracks, so that after unloading the gangue, the single-sided curved track side-discharge mine car enters the second pair of loaded car tracks along the third pair of tracks, and slides along the second pair of loaded car tracks to the empty car track by its own gravity.

[0015] Furthermore, an unloading curved track is laid on the unloading platform. The unloading curved track connects with the first pair of heavy-duty car tracks. The unloading curved track is used for the entry of single-sided curved track side-discharge mine cars and to complete single-sided unloading.

[0016] Furthermore, unloading the curve track includes:

[0017] The fourth pair of heavy-duty car rails is laid on the unloading platform and connects with the first pair of heavy-duty car rails;

[0018] The guide rail is set on one side at an angle, with its lower end close to the unloading platform and its upper end tilting upwards and close to the edge of the unloading platform.

[0019] The single-sided unloading track is horizontally set up. Its near end connects to the high end of the single-sided guide track, and its far end extends horizontally to the edge of the unloading platform. It is used for the single-sided curved track side-discharge mine car to stop and tilt and dump gangue.

[0020] The stop lever is set vertically, with its lower end fixedly connected to the far end of the single-sided unloading track, and its upper end extending upwards to limit the single-sided curved track side-discharge mine car, so that the single-sided curved track side-discharge mine car stops and dumps gangue.

[0021] The beneficial effects of this utility model are:

[0022] This utility model utilizes a single-sided curved rail side-discharge mine car to dump gangue to one side of the unloading platform, and a bottom-side unloading mine car to dump gangue to the other side of the unloading platform. This can increase the amount of gangue discharged and reduce the accumulation height of gangue in the dumping area, thereby expanding the gangue dumping area.

[0023] This invention sets a third pair of tracks at the junction of the first pair of loaded car tracks and the unloading platform, which connects to the second pair of loaded car tracks. This allows the single-sided curved track side-discharge mine car to enter the second pair of loaded car tracks along the third pair of tracks after unloading the gangue, and slide along the second pair of loaded car tracks to the empty car track by its own weight. At this time, the mine car loaded with gangue can continue to enter the first pair of loaded car tracks to dump the gangue, thereby increasing the gangue discharge per unit time.

[0024] This invention lays unloading curved rails on the unloading platform, allowing single-sided curved rail side-discharge mine cars to stop and tilt to dump gangue. A stop lever is used to limit the single-sided curved rail side-discharge mine cars, preventing them from moving forward. This facilitates the single-sided curved rail side-discharge mine cars to smoothly enter the unloading curved rails and complete single-sided unloading, thus improving the safety of the gangue discharge system.

[0033] The second pair of heavy-duty car tracks 2 are laid on the unloading platform above the gangue dumping area via trusses and are set parallel to the first pair of heavy-duty car tracks 1.

[0034] The single-sided curved track side-discharge mine car 3 travels on the first pair of heavy car tracks 1 and is used to pull gangue to the unloading platform and dump the gangue into the gangue dumping area.

[0035] The bottom-side unloading car travels on the second pair of heavy-duty car tracks 2 and is used to pull the gangue to the unloading platform and dump the gangue into the gangue dumping area.

[0036] The unloading platform is rectangular or square; a single-sided curved-rail side-discharge mine car 3 is used to dump gangue onto the first tilting side of the unloading platform, and a bottom-side unloading mine car is used to dump gangue onto the second tilting side of the unloading platform. This can both increase the amount of gangue discharged and reduce the accumulation height of gangue in the dumping area. The first and second tilting sides of the unloading platform are adjacent.

[0037] like Figure 1As shown, the junction of the first pair of loaded car tracks 1 and the unloading platform is connected to the second pair of loaded car tracks 2 via the third pair of tracks 4, so that the single-sided curved track side-discharge mine car 3 can enter the second pair of loaded car tracks 2 along the third pair of tracks 4 after unloading the gangue, and slide along the second pair of loaded car tracks 2 to the empty car track by its own gravity.

[0038] like Figure 2 As shown, this utility model also includes an unloading curved track 5, which is laid on the unloading platform and is connected to the first pair of heavy-duty car track 1.

[0043] The stop lever 9 is set vertically, with its lower end fixedly connected to the far end of the single-sided unloading track 8. The upper end of the stop lever 9 extends upward and is used to limit the single-sided curved track side-discharge mine car 3, preventing it from moving forward.

[0044] Example 1

[0045] The process of implementing this utility model in a certain mine is as follows:

[0046] Lay out the truss, and lay out the first pair of heavy-duty car rails 1, the second pair of heavy-duty car rails 2, the third pair of rails 4 on the truss, and make and install the unloading curved rails 5.

[0047] Purchase 5m 3 Single-sided curved rail side-discharge mine cars 3 and 1.5m 3 The wheelbase of the purchased single-sided curved rail side-discharge mine car 3 is 1300mm and the minimum turning radius is R9100mm. Therefore, the corresponding first pair of heavy car track 1 is adjusted at the bend and the corresponding JD-2.0 dispatch winch is installed.

[0048] Since the installation of this utility model at the mine, it has increased the amount of gangue transported per unit time. While meeting the gangue output requirements of underground tunneling, it also leaves a margin, ensuring efficient and rapid tunnel excavation and laying a certain foundation for the smooth completion of the entire mine construction project.

[0049] Calculations show that after using this utility model, the daily number of cage hoists at the mine will be reduced by 1141 / 6 - 1141 / 10 = 76 times while keeping the total hoisting volume unchanged. Based on a hoisting cost of 200 yuan per hoist, this will save 15,200 yuan per day. Assuming the main shaft is completed in one and a half years, this will save 15,200 yuan x 540 = 8,208,000 yuan, thus achieving the goal of cost reduction and efficiency improvement.

[0050] Calculations show that after using this invention, the mine's daily waste rock removal capacity increased from 850 m³ / h. 3 Increased to 1440m 3 Exceeding the daily coal production of 1141 cubic meters per second underground. 3 This ensures the sufficient amount of waste rock to be removed during tunnel excavation, effectively guaranteeing the smooth progress of tunnel excavation.
