Description

Technical Field

[0001] The present application relates to the technical field of mining equipment, and in particular to a platform for improving the efficiency of slag loading on a ramp. Background Art

[0002] During the construction of underground mine ramps, the use of slag loading platforms is a common loading method. However, when loading slag with mining trucks, due to the high height of mining trucks and limited ramp space, a specific site is often required for slag loading. Each time the slag is loaded, the shovel needs to be driven to the platform, which not only affects the loading efficiency of slag, but also prolongs the time for cleaning the slag on the ramp, and may even cause the slag on the ramp to be cleaned in time, affecting the efficiency of ramp excavation. Therefore, how to effectively improve the loading efficiency of ramp slag, improve the efficiency of cleaning the slag on the ramp, and thus speed up the ramp excavation efficiency has always been a problem that needs to be solved in the field of mine ramp construction technology.

The shoveling equipment travels between the ramp and the chamber through the gap.

[0006] Optionally, the chamber is provided with a supporting structure, which includes an anchor net and anchor rods; the anchor net is a metal net made of φ6mm steel bars with a length of 2m, a width of 1.2m, and a mesh size of 0.1m×0.1m; the anchor rod is a φ43mm, 1.8m long seamed steel pipe, and the anchor net is fixed by a pipe seam anchor rod.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0021] In view of the problems in the above background, the embodiment of the present application provides a platform for improving the efficiency of ramp slag loading, which can effectively avoid the problem that the height of mining trucks is high, the ramp space is limited, and a specific site is required for slag loading, as well as the problem that the construction period of a specific slag loading platform is long and the construction is slow, which restricts the construction of the ramp, greatly shortening the construction time and difficulty of the ramp slag loading platform. At the same time, the utility model has simple construction, low investment cost, convenient slag loading, and is safer and more reliable during the slag loading process, and has a wide range of application prospects.

[0022] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2 The platform for improving the slag loading efficiency of the ramp shown in the figure comprises a ramp 1, a car blocking wall 7 and a chamber 2. The chamber 2 is set as a three-center arch with a length of 10m, a cross section of 3m wide and 3m high. Specifically, the cross section of the chamber 2 is as follows Figure 3As shown, the overall height is 3m, of which the bottom 2m is a square, and the top 1m is an arc arch, and the depth is 10m. In this way, the chamber 2 has enough space for the shoveling equipment 5 to enter and perform slag dumping operations.

[0024] The chamber 2 of the present application is arranged perpendicularly to the ramp 1 on a plane, and the car-blocking wall 7 is arranged in the middle of the ramp 1 close to one side of the chamber 2. A gap for the shoveling equipment 5 to pass through is arranged between the entrance of the chamber 2 and the car-blocking wall 7, and the shoveling equipment 5 travels between the ramp 1 and the chamber 2 through the gap.

[0025] In the present application, during the excavation of the ramp 1, the opening of the chamber 2 is selected according to the site requirements and rock conditions. After the excavation and support of the chamber 2 are completed, the car-blocking wall 7 at the mouth of the chamber 2 is cast. After 72 hours of mold maintenance, the car-blocking wall 7 can be removed from the mold for use. The chamber 2 and the car-blocking wall 7 are combined with the ramp 1 to form a slag loading platform, which can quickly form slag loading conditions. The slag transportation equipment 6 normally transports slag in the ramp 1, and the shoveling equipment 5 normally travels back and forth between the ramp 1 and the chamber 2. When the shoveling equipment 5 enters the chamber 2, the slag collected by the front end can be poured forward into the slag transportation equipment. In this way, there is no need to go to a distant fixed slag transfer platform, which greatly shortens the construction time of the ramp slag loading platform and makes the slag loading process safer and more reliable. In addition, the slag loading platform can also be used for material storage in the later stage.

[0026] In one embodiment, in order to provide sufficient support for the chamber 2, the chamber 2 of the present application adopts full-section anchor mesh support. Specifically, the support structure includes an anchor mesh 3 and an anchor rod 4, wherein the anchor mesh 3 is a metal mesh made of φ6mm steel bars with a length of 2m, a width of 1.2m, and a mesh size of 0.1m×0.1m; the anchor rod 4 is a φ43mm, 1.8m long seam steel pipe; the anchor mesh 3 is fixed by the pipe seam anchor rod 4, so that the surrounding rock of the chamber is more stable.

[0027] In one embodiment, the car-blocking wall 7 of the present application has a length of 1.5 m, a wall thickness of 0.5 m, and a height of 0.5 m. It is cast with unreinforced C20 concrete. The length of the car-blocking wall is smaller than the width of the reverse chamber mouth, and travel space is left for the shovel loading equipment 5, facilitating the travel of the shovel loading equipment 5.

[0028] In the process of excavating and discharging slag on the ramp, when the ramp is far from the slag loading, the reverse chamber can be opened in a place with better rock conditions according to the on-site rock conditions and the shoveling distance, and the function of loading slag on the ramp is realized by adding a car blocking wall in the reverse chamber of the ramp to prevent the car from slipping and untimely braking, etc., effectively avoiding the problem that the mining truck is high in height, the ramp space is limited, and a specific site is required for slag loading, and the specific slag loading platform has a long construction period and slow construction, which restricts the construction of the ramp, greatly shortening the construction time and construction difficulty of the ramp slag loading platform. At the same time, the utility model has simple construction, low investment cost, convenient slag loading, and is safer and more reliable during the slag loading process, and has a wide range of application prospects.

[0029] Finally, it should be noted that, in this article, relationships such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms include, include or any other variations are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
