Description

Technical Field

[0001] The invention belongs to the field of coal mine production, and in particular relates to a system which can both increase the transportation volume of gangue and expand the dumping area of ​​gangue. Background Art

[0002] Coal gangue is solid waste discharged during coal mining and coal washing. It includes excavation gangue during tunnel excavation, gangue mined from the roof, floor and interlayer during mining, and washed gangue picked out during coal washing. Due to the large amount of coal gangue generated, how to effectively manage and treat these wastes has become an important issue.

[0003] Gangue discharge 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 gangue discharge equipment directly affect the gangue discharge capacity. In addition, effective management and planning are the key to improving gangue discharge capacity. For example, by optimizing the gangue discharge process, planning auxiliary tunnels, improving gangue discharge equipment and other measures, an efficient gangue discharge system can be formed.

[0004] The average daily amount of gangue discharged underground is affected by many factors, including tunneling speed, daily lifting times of cages, geological conditions, mining technology, management level, etc. There is a close relationship between the transportation capacity of the gangue discharge system and the average daily amount of gangue discharged underground. An efficient gangue discharge system can significantly improve the mining efficiency of coal mines and reduce production stagnation caused by poor gangue discharge. Therefore, the design and optimization of the gangue discharge system is crucial for the safe production and sustainable development of coal mines. However, due to the improvement of technical level and the acceleration of tunneling speed, the transportation capacity of the existing gangue transportation and unloading system can no longer meet the gangue production speed of underground excavation.

[0005] In the current gangue discharge system, fixed mine vehicles can only discharge gangue to one side of the unloading platform when transporting gangue to the unloading platform, so the accumulation height of gangue in the dumping area continues to increase, making it impossible to effectively expand the gangue dumping area, thus hindering the completion of subsequent gangue dumping. Summary of the invention

[0006] The purpose of the present invention is to provide a system that can both increase the transportation capacity of gangue and expand the area for gangue dumping, so as to solve the problem that the transportation capacity level of the existing gangue transportation and unloading system cannot meet the gangue production speed of underground excavation, and the area of ​​the gangue dumping is too small to hinder the dumping of gangue.

[0007] The present invention adopts the following technical solution: a system that can both increase the transportation volume of gangue and expand the dumping area of ​​gangue, comprising:

[0008] The first pair of heavy vehicle tracks are laid through trusses above the waste rock dumping area and on the unloading platform;

[0009] The second pair of heavy vehicle tracks are laid on the unloading platform above the gangue dumping area through trusses and are arranged parallel to the first pair of heavy vehicle tracks;

[0010] The single-side curved track side-dumping mine car runs on the first pair of heavy vehicle tracks and is used to pull the gangue to the unloading platform and dump the gangue into the gangue dumping area;

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

[0012] Among them, the unloading platform is rectangular or square;

[0013] Among them, the single-sided curved track side-unloading mine car is used to dump gangue to the first dumping side of the unloading platform, and the bottom-unloading mine car is used to dump gangue to the second dumping side of the unloading platform, thereby increasing the discharge volume of gangue and reducing 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 between the first pair of heavy vehicle tracks and the unloading platform is connected to the second pair of heavy vehicle tracks through the third pair of tracks, so that the single-sided curved track side-unloading mine car can enter the second pair of heavy vehicle tracks along the third pair of tracks after unloading the gangue, and slide along the second pair of heavy vehicle tracks to the empty vehicle tracks using its own gravity.

[0015] Furthermore, an unloading curved track is laid on the unloading platform, and the unloading curved track is connected to the first pair of heavy vehicle tracks. The unloading curved track is used for the single-side curved track side-unloading mine car to enter and complete the single-side unloading.

[0016] Further, unloading the curved track includes:

[0017] The fourth pair of heavy vehicle tracks are laid on the unloading platform and connected to the first pair of heavy vehicle tracks;

[0018] The single-side guide rail is tilted, with its lower end close to the unloading platform and its upper end tilting upward and close to the edge of the unloading platform;

[0019] The single-side unloading track is horizontally arranged, with its proximal end connected to the high end of the single-side guide track, and its distal end extending horizontally to the edge of the unloading platform, on which the single-side curved track side-unloading mine car stops and rolls over to dump the gangue;

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

[0021] The beneficial effects of the present invention are:

[0022] The present invention utilizes a single-side curved track side-discharging mine car to dump the gangue to one side of the unloading platform, and utilizes a bottom-side unloading mine car to dump the gangue to the other side of the unloading platform, which can not only increase the discharge amount of the gangue, but also reduce the accumulation height of the gangue in the dumping area, thereby expanding the gangue dumping area;

[0023] The present invention arranges a third pair of tracks at the junction of the first pair of heavy vehicle tracks and the unloading platform to connect with the second pair of heavy vehicle tracks, so that the single-side curved track side-unloading mine car can enter the second pair of heavy vehicle tracks along the third pair of tracks after unloading the gangue, and slide along the second pair of heavy vehicle tracks to the empty vehicle track by its own gravity. At this time, the mine car loaded with gangue can continue to enter the first pair of heavy vehicle tracks to dump the gangue, thereby increasing the gangue discharge per unit time.

[0024] The present invention lays an unloading curved track on the unloading platform so that the single-side curved track side-unloading mine car can stop and tip over to dump the gangue, and uses a stop lever to limit the single-side curved track side-unloading mine car to prevent the single-side curved track side-unloading mine car from moving forward, making it convenient for the single-side curved track side-unloading mine car to smoothly enter the unloading curved track and complete single-side unloading, thereby improving the safety of the gangue discharge system.

[0044] Example 1

[0045] The process of implementing the present invention in a certain mine is as follows:

[0046] Lay the truss, and lay the first pair of heavy vehicle tracks 1, the second pair of heavy vehicle tracks 2, the third pair of tracks 4 on the truss, and make and install the unloading curved track 5.

[0047] Purchase 5m 3 Single-side curved track side-dumping mine car 3 and 1.5m 3 The bottom side unloading mine car, the purchased single-sided curved rail side unloading mine car 3 has a minimum wheelbase of 1300mm and a minimum turning radius of R9100mm.
