Description

Technical Field

[0001] This application relates to the field of underground mining and transportation equipment technology, and in particular to an underground ore discharge structure for rapid ore discharge. Background Technology

[0002] In underground ore mining operations, ore chute discharge, a process where ore is transferred from the stope to the intermediate transport roadway, directly impacts mine production efficiency. Traditional ore passes, due to their slow discharge speed, result in long waiting times during loading, severely restricting underground ore transportation efficiency. Furthermore, the traditional method using a single vibratory ore pass is inefficient; the limited capacity of a single machine fails to meet the rapid ore discharge needs of mining companies. During periods of high ore production, this can lead to large ore accumulation in the pass, hindering efficient subsequent mining operations and ultimately reducing the overall operational efficiency of the underground ore mining system. Utility Model Content

[0003] To address or partially address the problems existing in related technologies, this application provides a rapid ore discharge underground ore discharge structure that optimizes the existing ore pass structure and achieves high-speed and uniform ore discharge based on two vibrating ore dischargers.

[0004] The first aspect of this application provides a rapid underground ore discharge structure, including: a ore pass, a first ore discharge machine, a second ore discharge machine, a middle transport roadway, and an operating chamber. The bottom of the ore pass is widened to form a funnel-shaped ore bin. The first and second ore discharge machines are installed in parallel at the bottom of the ore pass, and a middle transport roadway is set below it. Multiple mine cars are set in the middle transport roadway. The operating chamber is equipped with a control switch for controlling the opening and closing of the first and second ore discharge machines.

[0005] The control chamber is equipped with a controller, and laser sensors are installed on the middle transport roadway corresponding to the No. 1 and No. 2 ore feeders. The laser sensors are connected to the controller.

[0006] The controller is connected to indicator lights, which are installed in the operating chamber.

[0007] The technical solution provided in this application may include the following beneficial effects:

[0008] This application provides a rapid underground ore discharge structure that effectively improves ore discharge efficiency. The simultaneous operation of two vibratory ore dischargers significantly increases the overall ore discharge capacity, improving efficiency by 40%-60% compared to a single vibratory ore discharger. It also ensures uniform ore discharge; through reasonable layout and coordinated control, the two vibratory ore dischargers ensure even ore discharge from the ore pass, preventing ore segregation and ensuring uniform ore particle size distribution in subsequent ore processing, which is beneficial for stabilizing processing technology and improving product quality. Furthermore, it effectively reduces energy consumption and equipment wear. Simultaneous discharge by two vibratory ore dischargers shortens discharge time, avoiding prolonged high-load operation of a single device. The reasonable operating conditions reduce wear on equipment components, extend the service life of the vibratory ore dischargers, and lower equipment replacement and maintenance costs.

Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0015] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0016] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0017] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0018] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 The diagram illustrates a rapid ore discharge underground structure, comprising: a ore pass 1, a first ore discharge machine 2, a second ore discharge machine 3, an intermediate transport roadway 5, and an operating chamber 6. The bottom of the ore pass 1 is widened to form a funnel-shaped ore bin, which can accommodate the parallel installation of the first ore discharge machine 2 and the second ore discharge machine 3. The intermediate transport roadway 5 is located below the first ore discharge machine 2 and the second ore discharge machine 3, and multiple mine cars 4 are installed within it. The operating chamber 6 contains control switches for controlling the opening and closing of the first ore discharge machine 2 and the second ore discharge machine 3.

[0020] The bottom of the ore pass 1 is widened to form an ore bin, which can accommodate two vibrating ore feeders. The dimensions of the ore cars 4 are measured in the bottom area of ​​the widened ore pass 1. One vibrating ore feeder is installed in the center of each of the two adjacent ore cars 4. The electric locomotive drives the transport ore cars 4 from the middle transport roadway 5 and stops when it reaches the vibrating ore feeder. The operator in the operating chamber 6 turns on the vibrating ore feeder control switch, and the two vibrating ore feeders operate simultaneously to open the gate, and the ore flows from the ore pass 1 into the two adjacent ore cars 4.

[0021] Furthermore, to facilitate operators' confirmation of the arrival of the mine car 4, a controller and indicator lights are installed in the operating chamber 6, with the indicator lights mounted next to the control switch. Laser sensors are installed on the intermediate transport roadway 5 corresponding to the No. 1 ore feeder 2 and the No. 2 ore feeder 3, and the laser sensors are connected to the controller.

[0022] The laser sensor determines the position of the mine car 4 by emitting a laser beam and detecting the reflected light. In the intermediate transport roadway 5, a laser sensor is installed at a suitable position directly below the feeder. When the mine car 4 enters the detection range of the laser beam, the laser is reflected by the mine car 4, accurately detecting whether the mine car 4 has reached the designated position. When both laser sensors detect the arrival of the mine car 4, the controller issues a command to illuminate the warning light according to preset logic. When both laser sensors detect the arrival of the mine car 4, the warning light illuminates green, informing the operator that the conditions for opening the vibration ore discharge control switch have been met.

[0023] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0024] The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the units can be selected to achieve the purpose of this embodiment according to actual needs.

[0025] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
