The method of slurry filling is usually: the slurry is transported to the designated pit by pipeline, and the slurry uses its own gravitational potential energy to descend to fill the pit.

[0046] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0047] Considering that the total gravitational potential energy G1 of the slurry is much greater than the gravitational potential energy G2 required to fill the mine, at this time, the gravitational potential energy G1-G2 is wasted. Based on this, the embodiment of the present application provides a method, device, electronic device and medium for utilizing the gravitational potential energy of slurry filling to recycle the excess gravitational potential energy and improve the utilization rate of the total gravitational potential energy of the slurry, which is described below through an embodiment.

[0048] To facilitate understanding of this embodiment, a method for utilizing the gravitational potential energy of slurry filling disclosed in the embodiment of this application is first described in detail. Figure 1 As shown, the following steps S101-S104 are included:

[0049] S101: Determine the vertical height between the mine pit to be filled and the ground, and the total length of the slurry conveying pipeline set up for filling the mine pit; wherein, the outlet of the slurry conveying pipeline is set at the mine pit, and the inlet of the slurry conveying pipeline is set on the ground; the slurry conveying pipeline is used to transport the slurry on the ground to the mine pit through the gravitational potential energy of the slurry itself.

[0050] In this embodiment, the mine pit to be filled refers to a pit formed after mining. Generally, the distance between the mine pit and the ground is relatively far.

[0051] like Figure 2 As shown, the vertical height between the mine pit to be filled and the ground is H, and the total length of the slurry conveying pipeline set up to fill the mine pit is L=L1+L2+L3+L4+L5.

[0052] Usually, the outlet of the slurry conveying pipeline is set above the mine pit, so that the slurry from the outlet can fall directly into the mine pit. The slurry and the inlet of the slurry conveying pipeline are set on the ground, so that the slurry on the ground can be transported to the mine pit through the slurry conveying pipeline by utilizing the gravity potential energy of the slurry itself.

[0053] S102: Calculate the total gravitational potential energy of the slurry filled into the mine through the slurry conveying pipeline within the target time according to the total weight of the slurry filled into the mine through the slurry conveying pipeline within the target time and the vertical height.

[0054] In this embodiment, filling the mine pit with slurry is a long-term process, so the target duration can be one year, multiple years, or several months, which is not limited in this application.

[0055] In this embodiment, the total weight G of the slurry filled into the mine through the slurry delivery pipeline within the target time is:

[0056] G=mg

[0057] Wherein, m represents the total mass of slurry filled into the mine through the slurry delivery pipeline within the target time, and g is the gravitational acceleration.

[0058] The total gravitational potential energy E of the slurry filled into the mine through the slurry delivery pipeline within the target time P for:

[0059] E P =mgH

[0060] S103: Calculate the gravitational potential energy to be utilized of the slurry according to the vertical height and the total length, as well as the total gravitational potential energy.

[0061] In this embodiment, the gravitational potential energy of the slurry to be utilized is actually equal to the difference between the total gravitational potential energy of the slurry and the gravitational potential energy required to fill the mine.

[0062] In a possible implementation manner, when executing step S103, the following steps S1031-S1033 may be specifically performed:

[0063] S1031: Determine the filling multiple experience value and the actual filling multiple value according to the vertical height and the total length.

[0064] In this embodiment, the filling multiple empirical value is determined according to the vertical height H. For example, when the vertical height H=500 meters, the filling multiple empirical value may be equal to 8.

[0065] Calculate the ratio of the total length L to the vertical height H to get the actual filling multiple value.

[0066] S1032: Calculate the difference between the filling multiple experience value and the actual filling multiple value to obtain the remaining multiple.

[0067] S1033: Calculate the gravitational potential energy to be utilized of the slurry based on the filling multiple experience value, the remaining multiple, and the total gravitational potential energy.

[0068] In this embodiment, the ratio of the remaining multiple to the empirical value of the filling multiple is calculated to obtain the remaining multiple ratio; the product of the remaining multiple ratio and the total gravitational potential energy is calculated to obtain the gravitational potential energy to be utilized of the slurry.

[0069] S104: Determine parameter values ​​of parameters of each component in the energy conversion device according to the gravitational potential energy to be utilized, slurry parameters of the slurry, and the inner diameter of the slurry conveying pipeline; wherein the determined parameter values ​​are used to adjust the parameters of each component in the energy conversion device; the energy conversion device after parameter adjustment is used to be arranged in the slurry conveying pipeline, and in the process of conveying the slurry on the ground to the mine pit through the gravitational potential energy of the slurry itself, the gravitational potential energy to be utilized of the slurry is converted into electrical energy.

[0070] In a possible implementation, Figure 3 As shown, the energy conversion device includes rotating blades, a transmission device and a generator; wherein the rotating blades are used to convert the gravitational potential energy of the slurry to be utilized into rotational mechanical energy, the transmission device is used to transfer the rotational mechanical energy to the generator; and the generator is used to convert the rotational mechanical energy into electrical energy.

[0071] In this embodiment, the generator is connected to the energy storage device or the power grid. After converting the gravitational potential energy to be utilized into electrical energy, the generator stores the converted electrical energy in the energy storage device or directly transmits it to the power grid.

[0072] Slurry parameters include any one or more of the following: slurry concentration, slump, and spread.

[0073] When executing step S104, the following steps S1041-S1043 may be specifically performed:

[0074] S1041: Determine the number of rotating blades according to the slurry parameters; wherein the number of blades is negatively correlated with the slurry concentration, positively correlated with the slump, and positively correlated with the expansion.

[0075] In this embodiment, the higher the slurry concentration, the fewer the number of blades; the lower the slurry concentration, the more the number of blades.

[0076] Slump refers to the final deformation of the slurry after it flows due to its own gravity and stops due to internal resistance. It is one of the quantitative indicators of slurry fluidity. The larger the slump, the more leaves there are; the smaller the slump, the fewer leaves there are.

[0077] The expansion degree indicates that the slurry flows in the form of a colloid, and can also indicate the relative movement between the solid particles inside the slurry. In slurry testing, the expansion degree usually refers to the difference between the maximum radius and the minimum radius of the slurry after collapse (under certain conditions, such as when the difference between the maximum radius and the minimum radius of the slurry after collapse is within 50mm, measure and take the average value) or the height change of the slurry after pushing. Among them, the greater the expansion degree, the more blades there are; the smaller the expansion degree, the fewer blades there are.

[0078] S1042: Determine the blade size of the rotating blade according to the inner diameter of the pipeline; wherein the blade size is smaller than the inner diameter of the pipeline.

[0079] In this embodiment, the size of the blade is smaller than the inner diameter of the pipe, ensuring that the rotating blade can rotate in the pipe.

[0080] S1043: Determine the speed ratio of the speed increaser in the transmission device and the speed of the generator according to the gravitational potential energy to be utilized.

[0081] This embodiment does not specifically limit the execution order of steps S1041, S1042, and S1043.

[0082] In a possible implementation, when the energy conversion device is arranged in the slurry conveying pipeline, it is specifically used to:
