[0019] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] The filling preparation station 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. Figure 1-Figure 4 As shown, the filling preparation station 100 according to an embodiment of the present invention includes a first material bin 11, a second material bin 12, a first conveying chamber 21, a first conveying device 31, a second conveying chamber 22, a second conveying device 32, a stirring chamber 23, a stirring device 33 and a first conveying pipe 41.

[0021] The first conveying device 31 is arranged in the first conveying chamber 21, and the receiving end of the first conveying device 31 cooperates with the discharge port of the first material bin 11, so that the first conveying device 31 can convey the material in the first material bin 11. The second conveying device 32 is arranged in the second conveying chamber 22, and the receiving end of the second conveying device 32 cooperates with the discharge port of the second material bin 12, so that the second conveying device 32 can convey the material in the second material bin 12.

[0022] The stirring chamber 23 is located below each of the first conveying chamber 21 and the second conveying chamber 22, and the stirring device 33 is disposed in the stirring chamber 23. The feeding port of the stirring device 33 cooperates with each of the discharging end of the first conveying device 31 and the discharging end of the second conveying device 32, so as to stir the materials conveyed by the first conveying device 31 and the second conveying device 32. The first end of the first conveying pipe 41 is connected to the discharging port of the stirring device 33, and the second end of the first conveying pipe 41 can extend to the filling area.

[0023] The filling preparation station 100 according to the embodiment of the present invention can be provided with the first conveying chamber 21, the second conveying chamber 22 and the stirring chamber 23, so that the main part of the filling preparation station 100 can be arranged underground. This can not only save the industrial site on the surface of the mine, but also enable the filling preparation station 100 to meet higher environmental protection requirements, and further enable the filling preparation station 100 to be arranged at a position close to the filling area of ​​the mine, so as to reduce the length of the first conveying pipe 41 and improve the economy of the filling preparation station 100.

[0024] Moreover, by locating the stirring chamber 23 below the first conveying chamber 21 and the second conveying chamber 22, the underground excavation space can be greatly reduced, thereby not only greatly improving the stability and safety of the filling preparation station 100, but also reducing the difficulty of supporting the stirring chamber 23, the first conveying chamber 21 and the second conveying device 32.

[0025] Therefore, the filling preparation station 100 according to the embodiment of the present invention has the advantages of occupying a small industrial site, being environmentally friendly, having high stability, good safety, and good economy.

[0026] like Figure 1-Figure 4 As shown, the filling preparation station 100 includes a first material bin 11, a second material bin 12, a first conveying chamber 21, a first conveying device 31, a second conveying chamber 22, a second conveying device 32, a stirring chamber 23, a stirring device 33 and a first conveying pipe 41. The filling preparation station 100 can be adjacent to the ventilation channel and the escape channel of the mine system. In this way, the ventilation channel and the escape channel of the filling preparation station 100 can be better integrated with the ventilation channel and the escape channel of the mine, so that the construction amount of the ventilation channel and the escape channel of the filling preparation station 100 can be reduced, so as to reduce the construction cost of the filling preparation station 100.

[0027] The first material bin 11 is a horizontal bin, and dry sand and tailings can be contained in the first material bin 11. The second material bin 12 is a vertical bin, and cement can be contained in the second material bin 12. Each of the first material bin 11 and the second material bin 12 is arranged underground. By arranging each of the first material bin 11 and the second material bin 12 underground, not only can the area of ​​the industrial site occupied by the filling preparation station 100 be further reduced, so as to further save the industrial site on the surface of the mine, but also the filling preparation station 100 can meet higher environmental protection requirements.

[0028] By making the first material bin 11 a horizontal bin, the number of first material bins 11 can be reduced. That is, if the first material bin 11 is a vertical bin, two first material bins 11 need to be provided; if the first material bin 11 is a horizontal bin, only one first material bin 11 needs to be provided. This not only reduces the construction cost of the filling preparation station 100, but also facilitates the arrangement of the first material bin 11 and the second material bin 12.

[0029] like Figure 1-Figure 3 As shown in FIG. 1 , the first conveying chamber 21 is located below the first material bin 11, and the second conveying chamber 22 is located below the second material bin 12. Figure 3 As shown by arrow A in FIG.

[0030] The first conveying device 31 is arranged in the first conveying chamber 21, and the receiving end of the first conveying device 31 cooperates with the discharge port of the first material bin 11, so that the first conveying device 31 can convey the material in the first material bin 11. The second conveying device 32 is arranged in the second conveying chamber 22, and the receiving end of the second conveying device 32 cooperates with the discharge port of the second material bin 12, so that the second conveying device 32 can convey the material in the second material bin 12.

[0031] Optionally, the first conveying device 31 is a quantitative feeder, and the second conveying device 32 is a screw feeder. The length of the first conveying device 31 is greater than or equal to a preset value. In this way, the first material bin 11 and the mixing chamber 23 can be separated by a preset distance, so that the two large excavation projects can be separated, so that the engineering structure of the first material bin 11 and the engineering structure of the mixing chamber 23 will not affect each other.

[0032] like Figure 1-Figure 3 As shown, the stirring chamber 23 is located below each of the first conveying chamber 21 and the second conveying chamber 22. Optionally, the stirring chamber 23 is connected to each of the first conveying chamber 21, the second conveying chamber 22 and the filling chamber 24. This can make the structure of the filling preparation station 100 more reasonable.

[0033] The stirring chamber 23 may be adjacent to the equipment transportation layer of the mine. This allows the equipment transportation layer of the filling preparation station 100 to be well integrated with the equipment transportation layer of the mine, thereby reducing the construction volume of the equipment transportation layer of the filling preparation station 100, so as to reduce the construction cost of the filling preparation station 100. Moreover, by making the stirring chamber 23 adjacent to the equipment transportation layer of the mine, the stirring chamber 23 can be used as the main equipment transportation layer of the filling preparation station 100. Since the stirring device 33 is a large piece of equipment of the filling preparation station 100, the difficulty of equipment transportation can be reduced by using the stirring chamber 23 as the main equipment transportation layer of the filling preparation station 100.

[0034] The stirring device 33 is transported to the stirring chamber 23 through the equipment transportation layer of the mine. The first conveying device 31, the second conveying device 32 and the filling pump 47 can be first transported to the stirring chamber 23 through the equipment transportation layer of the mine, and then transported to the corresponding chamber through the lifting hole.

[0035] like Figure 2 and Figure 3 As shown, the stirring device 33 is disposed in the stirring chamber 23. The feed port of the stirring device 33 cooperates with each of the discharge end of the first conveying device 31 and the discharge end of the second conveying device 32 to stir the materials conveyed by the first conveying device 31 and the second conveying device 32.

[0036] Optionally, the stirring device 33 includes a first spiral stirrer 331 and a second spiral stirrer 332, the feed port of the first spiral stirrer 331 cooperates with each of the discharge end of the first conveying device 31 and the discharge end of the second conveying device 32, the discharge port of the first spiral stirrer 331 is connected to the feed port of the second spiral stirrer 332, and the discharge port of the second spiral stirrer 332 is connected to the first end of the first conveying pipe 41.

[0037] like Figure 1-Figure 4 As shown, the filling preparation station 100 further includes a filling chamber 24 and a second conveying pipe 42. The filling chamber 24 is located below the stirring chamber 23, and the filling chamber 24 has an accident pool 2. The first end of the second conveying pipe 42 is connected to the discharge port of the stirring device 33, and the second end of the second conveying pipe 42 is connected to the accident pool 2. The first end of the first conveying pipe 41 is connected to the discharge port of the stirring device 33, and the second end of the first conveying pipe 41 can extend to the filling area.

[0038] By locating the filling chamber 24 below the stirring chamber 23, the underground excavation space can be further reduced, thereby not only further improving the stability and safety of the filling preparation station 100, but also reducing the difficulty of supporting the stirring chamber 23, the filling chamber 24, the first conveying chamber 21 and the second conveying device 32.

[0039] Furthermore, by providing the filling chamber 24 with the accident pool 2 and the second delivery pipe 42 connected to the accident pool 2, the filling material in the stirring device 33 can be delivered to the accident pool 2 when an accident or failure occurs. This can prevent the filling material from being unable to leave the stirring device 33. Since the filling material solidifies after a period of time, if the filling material cannot leave the stirring device 33, the filling material will block the stirring device 33.

[0040] like Figure 1 As shown, the filling preparation station 100 further includes a filling pump 47, which is located in the filling chamber 24 and is arranged on the first conveying pipe 41. By providing the filling pump 47, the filling material can be conveyed to the filling area above the stirring chamber 23, thereby expanding the application range of the filling preparation station 100.

[0041] like Figure 1 As shown, the filling preparation station 100 further includes a first high-pressure water pipe 43, an additional water pipe 44, a second high-pressure water pipe 45 and a third high-pressure water pipe 46. The water outlet of the first high-pressure water pipe 43 is connected to the feed port of the stirring device 33, so that the stirring device 33 can be flushed by the first high-pressure water pipe 43. The water outlet of the additional water pipe 44 is connected to the feed port of the stirring device 33, so that water, dry sand, tailings and cement are mixed through the stirring device 33 to obtain filling materials.

[0042] The water outlet of the second high-pressure water pipe 45 is connected to the first delivery pipe 41, and the water outlet of the second high-pressure water pipe 45 is located upstream of the filling pump 47. The water outlet of the third high-pressure water pipe 46 is connected to the first delivery pipe 41, and the water outlet of the third high-pressure water pipe 46 is located downstream of the filling pump 47. Thus, the filling pump 47 can be flushed by the second high-pressure water pipe 45, and the part of the first delivery pipe 41 located downstream of the filling pump 47 can be flushed by the third high-pressure water pipe 46.

[0043] Among them, "upstream" and "downstream" are determined according to the flow direction of the filling material in the first conveying pipe 41. The filling material first flows through the water outlet end of the second high-pressure water pipe 45 and then flows through the filling pump 47. The filling material first flows through the filling pump 47 and then flows through the water outlet end of the third high-pressure water pipe 46.

[0044] The present invention also provides a mining system. The mining system according to an embodiment of the present invention includes a mine and a filling preparation station 100 according to the above embodiment of the present invention. The mine has a ventilation passage, an escape passage, and an equipment transportation layer. The filling preparation station 100 is adjacent to the ventilation passage and the escape passage, and the stirring chamber 23 of the filling preparation station 100 is adjacent to the equipment transportation layer.
