[0002] With the strengthening of safety supervision in the mining industry and the improvement of mine production safety awareness and management concepts, more and more attention has been paid to the production management of mine spoil dumps. Due to complex site conditions, the single-step slope of the spoil dump is prone to be high, the road layout is difficult under complex terrain conditions, the project volume is huge, and safety accidents caused by heavy rock transport vehicles going downhill often occur.

[0003] In view of this, the present invention is proposed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a method for draining and dumping spoil in a spoil dump under complex site conditions, so as to solve the technical problem of reducing the height of the spoil dump slope and reducing the mining production demand of heavy vehicles going downhill under complex site conditions.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A method for dumping soil in a dump under complex site conditions by draining and dumping soil in reverse, comprising the following steps:

[0007] S100, determining the number of chutes according to the total amount of discarded materials and the discharge specifications of the chutes;

[0008] S200, determining the number and size of the bottom storage yard according to the number of chutes and the types of abandoned materials;

[0009] S300, determining the number of unloading stations and the plane size of the unloading platform according to the number of chutes and the type of transport vehicles;

[0010] S400, determining the minimum spacing of the chutes according to the plane size of the unloading platform and the size of the bottom yard;

[0011] S500, build connecting roads and chutes, and then carry out sluicing and reverse discharge operations.

[0012] Preferably, in step S100:

[0013] The chute discharge specifications include the depth of the chute, the width of the bottom of the chute and the slope of the chute.

[0014] Preferably, in step S200:

[0015] The number of the chutes is the same as the number of the bottom yards.

[0016] Preferably, in step S300:

[0017] The number of unloading stations is the product of the number of chutes and the number of types of transport vehicles.

[0018] Preferably, in step S300:

[0019] There are two types of transport vehicles, and every two unloading stations correspond to a set of chutes.

[0040] S300, determining the number of unloading stations 4 and the plane size of the unloading platform 3 according to the number of chutes 1 and the type of transport vehicles;

[0041] Among them, Figure 1 As shown, in the above steps, the number of unloading stations 4 is the product of the number of chutes 1 and the number of transport vehicle types. Generally, there are two types of transport vehicles, which is equivalent to the number of unloading stations 4 being twice the number of chutes 1, so that every two unloading stations 4 correspond to a group of chutes 1.

[0042] like Figure 1 As shown, in a preferred embodiment of the present invention, the chute 1 is located in the middle of two corresponding unloading stations 4.

[0043] S400, determining the minimum spacing of the chutes 1 according to the plane size of the unloading platform 3 and the size of the bottom yard 2;

[0044] Among them, Figure 2 As shown, in the above steps, a heavy vehicle line 6 and an empty vehicle line 7 are set on the unloading platform 3, which are used for the fully loaded and unloaded vehicle routes respectively. In this way, the empty vehicle and the fully loaded vehicle travel according to their own routes respectively, which further promotes the soil discharge efficiency.
