Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
As shown in fig. 1 and 2, a system 1 for processing waste rock in a mine according to an embodiment of the present invention includes a first conveying device (not shown), a crushing device 10, a screening device 20, and a storage device (not shown).
First conveyor, breaker 10, sieving mechanism 20 and storage device all establish in the mine, and first conveyor is used for carrying the barren rock that the in-process produced of exploiting in the mine, and breaker 10 is used for breaking into the rubble of different granularities with the barren rock in the mine, and sieving mechanism 20 is used for sorting out the rubble of different granularities, and storage device is used for storing different types of rubble respectively.
Specifically, in the actual processing process, the waste rocks generated in the mining process in the mine are conveyed to the crushing device 10 through the first conveying device for crushing, then the crushed gravels are sorted through the screening device 20, and the sorted gravels with different particle sizes are stored in the storage device.
The inventor finds that in the related art, the waste rock in the mine is transported to the ground surface through the material vehicle for processing, the transportation cost of the waste rock is high, and the processing and the accumulation of the waste rock on the ground surface cause environmental pollution.
According to the processing system 1 for the waste rock in the mine, provided by the embodiment of the invention, the first conveying device, the crushing device, the screening device and the storage device are arranged in the mine, so that the processing process of the waste rock can be finished in the mine, the environmental pollution is avoided, the transportation cost of the waste rock can be reduced, and the cost is saved.
In some embodiments, as shown in fig. 1 and 2, the mine has a crushing chamber 30 and a sand storage chamber 40 arranged at intervals, the crushing device 10 is arranged in the crushing chamber 30, and the storage device is arranged in the sand storage chamber 40. Therefore, the crushing chamber 30 and the sand storage chamber 40 can form mutually independent accommodating spaces, so that the crushing devices and the crushed stones are placed in order, the operation of the crushing devices is not easy to interfere, the distribution in the mine can be optimized, and safety accidents caused by random accumulation of the crushed stones are avoided.
In some embodiments, as shown in fig. 2, the mine further includes a waste rock transport mine 50 and a waste rock chute 60, the first conveyor being located within the waste rock transport mine 50, the waste rock chute being located below the waste rock transport mine 50, a first end of the waste rock chute 60 (an upper end of the waste rock chute 60 in fig. 2) being in communication with the waste rock transport mine 50, and a second end of the waste rock chute 60 (a lower end of the waste rock chute 60 in fig. 2) being in communication with the crushing chamber 30.
Specifically, as shown in fig. 1 and 2, the crushing chamber 30 is located below the waste rock transportation tunnel 50, and a waste rock chute 60 is connected between the waste rock transportation tunnel 50 and the crushing chamber 30 and communicates the waste rock transportation tunnel 50 and the crushing chamber 30. The first conveyor transports the waste rock along the waste rock transport mine 50 to the upper end of the waste rock chute 60, where the waste rock is then placed into the waste rock chute 60, along which the waste rock may fall into the crushing chamber 30. It should be noted that in this embodiment, the waste rock chute 60 may be arranged vertically or obliquely, depending on the environment in the mine.
From this, can utilize the gravity of barren rock self to realize the transfer of barren rock in the barren rock chute, simultaneously, adopt the mode of overall arrangement from top to bottom, can carry out three-dimensional arrangement with barren rock transportation ore way, barren rock chute and broken chamber, improve the utilization ratio in unit space, be favorable to optimizing the mine structure.
In some embodiments, the second end of the waste ore shaft 60 is provided with a control gate for communicating the waste ore shaft 60 with the crushing chamber 30 and disconnecting the waste ore shaft 60 from the crushing chamber 30. Thus, the waste rock chute can be used as a waste rock conveying passage as well as a waste rock storage space.
It will be appreciated that to avoid the high frequency of opening and closing of the crushing unit 10, it is generally necessary to bin the waste rock to a certain level and then uniformly crush it. Specifically, before the crushing device 10 is opened, the control gate disconnects the waste rock chute 60 from the crushing chamber 30, waste rock is placed in the waste rock chute 60 and then stored in the waste rock chute 60, and when the waste rock stored in the waste rock chute 60 reaches the pretreatment capacity, the control gate connects the waste rock chute 60 and the crushing chamber 30 so that the waste rock falls into the crushing chamber 30.
In some embodiments, the crushing device 10 is disposed adjacent to the waste chute 60 with the feed opening of the crushing device 10 disposed opposite the second end of the waste chute 60. In other words, the feed opening of the crushing device 10 is opposite to the second end of the waste rock chute 60 in the up-down direction. Therefore, when the control valve is communicated with the waste rock chute 60 and the crushing chamber 30, waste rocks in the waste rock chute 60 directly fall into the feeding hole of the crushing device 10 under the action of gravity, and special feeding equipment does not need to be arranged for the crushing device 10, so that the cost is saved.
