REINFORCEMENT DEVICES AND PROCESSES IN THE FLOWING OF LU504494
UNDERGROUND BACKFILL SLURRY
The present invention relates to the field of mine filling technology, particularly a kind of reinforcement devices and processes in the flowing of underground backfill slurry.
Backfill mining method is one of the important mining methods in the mining field, and the preparation and transportation of filling slurry in this method directly affect the quality of backfill body, and have a significant impact on the safety of mine filling. With the deepening of the research on the preparation methods of filling slurry, it has been found that adding an appropriate amount of reinforcement materials (such as steel fibers, polyethylene fibers, straw fibers, etc.) to the filling slurry can not only improve the strength of the backfill body but also reduce the volume of cement and the cost of filling.
Currently, there is only one method for reinforcing filling slurry, that is, directly add reinforcement materials into the slurry during the preparation process, mix them well before transporting the filling slurry to the underground voids through filling pipelines. However, due to the significant differences in the physical and chemical properties between the reinforcement materials and the cement, tailings, etc. in the filling slurry, they cannot be mixed well. Most reinforcement materials tend to float on the upper layer of the filling slurry. Even if they are uniformly mixed on the surface, during long-distance transportation through pipelines, the reinforcement materials can be unevenly distributed due to the segregation effect, and may even cause pipe blockage.
The existing technologies have provided a filling material containing straw fibers and its application in backfill mining. First, mix straw fibers, cement, graded tailings, and rod-milled sand in a mixer, then add water to the mixture and stir it evenly in an agitator to prepare the filling slurry. Although with this technology straw fibers are added to enhance the strength of the subsequent backfill body during the preparation of filling slurry, the straw fibers tend to separate from the slurry during long-distance transportation through filling pipelines, leading to pipe blockage. 1/16
Therefore, it is necessary to design a reinforcement device with simple structure and, 4494 process to be used in the flowing of underground filling slurry toavoid the separation between reinforcement materials and slurry during transportation.
To solve the above problems, the present invention provides a reinforcement device and process used in the flowing of underground filling slurry. It introduces high-pressure air into the high-pressure reinforcement hoppers, driving the reinforcement materials to be added into the filling pipeline under the action of high-pressure air, and thoroughly mixed with the flowing slurry. This not only improves the quality of the backfill body but also reduces the volume of cement and the cost of filling.
To achieve the above objectives, the technical solution adopted by the present invention includes:
A reinforcement device used in the flowing of underground filling slurry, comprising two sets of high-pressure reinforcement hoppers with inlet and outlet ports, high-pressure air input components that supply high-pressure air to the two sets of high-pressure reinforcement hoppers, and reinforcement material conveying pipelines that are connected to the discharge ports of the two sets of high-pressure reinforcement hoppers and to the filling pipeline at the other end. The reinforcement material conveying pipelines are equipped with reinforcement material conveying control components, and an air-liquid separation air cushion is provided at the connection between the reinforcement material conveying pipelines and the filling pipeline.
Furthermore, the high-pressure air input components comprise an underground high-pressure air pipe, a high-pressure air input manifold connected to one end of the underground high-pressure air pipe, and two sets of high-pressure air input branches connected to the other end of the high-pressure air input manifold. The two sets of high-pressure air input branches are respectively connected to two sets of air inlets provided on the two sets of high-pressure reinforcement hoppers
The high-pressure air input manifold is equipped with an underground high-pressure air valve and a pressure gauge, and the two sets of high-pressure air input branches are respectively equipped with a first manual valve and a second manual valve. 2/16
The outlet ports are set at the bottom of the high-pressure reinforcement hoppers, and the 50 4494 reinforcement material conveying pipelines comprise two sets of discharge branches connected to the outlet ports of the high-pressure reinforcement hoppers, and a discharge manifold connected to the other end of the two sets of discharge branches. The other end of the discharge manifold is connected to the filling pipeline, and the discharge manifold and the filling pipeline are arranged perpendicular to each other.
The two sets of discharge branches are respectively equipped with a third manual valve and a fourth manual valve, and the reinforcement material conveying control components and the air-liquid separation air cushion are provided on the discharge manifold.
The air-liquid separation air cushion is set at the bottom of the discharge manifold, and the reinforcement material conveying control components comprise an electromagnetic valve located in the middle of the discharge manifold, and a control device connected to the electromagnetic valve. The control device comprises a control switch, a control chip, and a power battery.
Both the discharge branches and the discharge manifold are made of high-pressure rubber air pipes, and their inner diameter is 5 to 8 times greater than the maximum length of the reinforcement material.
The feed ports are set at the top of the high-pressure reinforcement hoppers, and a high-pressure sealing ring is provided on the feed ports.
A safety valve and a support are provided at the top and the bottom of the high-pressure reinforcement hoppers, respectively.
A reinforcement process used in the flowing of underground filling slurry is adopted using the above-mentioned reinforcement device, comprising the following steps:
S1: Install the reinforcement device at a distance of 10 to 15 meters from the filling outlet.
After installation, set the switching frequency and time of the electromagnetic valve in the control chip according to the amount of reinforcement material to be added, and then turn on the control switch.
S2: Open the feed port of one set of high-pressure reinforcement hoppers, and add the 3/16 reinforcement material. Then, close the feed port and tighten the high-pressure sealing ring. After, 504494 adding, open the first manual valve and the third manual valve, then open the underground high-pressure air valve and ensure that the reading on the pressure gauge is 0.1 MPa higher than the pressure in the filling pipeline.
S3: When the current set of high-pressure reinforcement hoppers are conveying material, open the feed port of the other set of high-pressure reinforcement hoppers and add the reinforcement material. Then, close the feed port and tighten the high-pressure sealing ring.

S4: Repeat steps S1 to S3 until the filling operation is completed. Then sequentially close the control switch, the fourth manual valve/third manual valve, the second manual valve/first manual valve, and the underground high-pressure air valve.
Compared to existing technologies, the beneficial effects of the present invention are as follows: 1. The reinforcement device and process in the flowing of underground filling slurry in the present invention involve the installation of two sets of high-pressure reinforcement hoppers at a distance of 10 to 15 meters from the filling outlet in the underground filling process.
High-pressure air is introduced into the hoppers, driving the reinforcement materials to be added into the horizontal filling pipeline. Under the action of high-pressure air, the reinforcement materials are well mixed with the flowing slurry. This not only improves the quality of the backfill body but also reduces the volume of cement, thereby reducing the filling cost.
The reinforcement device and process in the flowing of underground filling slurry in the present invention utilize high-pressure air as the power source for transporting the reinforcement materials. This enables the transportation of reinforcement materials into the filling pipeline, and ensures uniform mixing with the filling slurry. The impact of high-pressure air also assists in homogenizing the filling slurry and addressing situations where the slurry is unevenly mixed or prone to layering, thereby improving the workability of the filling slurry.

As shown in Fig. 1, a reinforcement device 100 in the flowing of underground filling slurry comprises two sets of high-pressure reinforcement hoppers 10, each with a feed port 13 and a discharge port. The high-pressure air input components are connected to the two sets of reinforcement hoppers 10, and a reinforcement material conveying pipeline is connected to the respective discharge ports of the reinforcement hoppers. The other end of the reinforcement 5/16 material conveying pipeline is connected to the filling pipeline 30. A reinforcement material 5) 4494 conveying control component is set on the reinforcement material conveying pipeline, and an air-liquid separation air cushion is installed at the connection between the reinforcement material conveying pipeline and the filling pipeline 30. The amount of reinforcement material added is controlled by the reinforcement material conveying control component.
High-pressure reinforcement hoppers 10 are set underground at a distance of 10-15m from the filling discharge port to ensure sufficient time for uniform mixing of the reinforcement material. The slurry inside the filling pipeline 30 has an initial flow velocity, and although the viscosity coefficient increases significantly after adding the reinforcement material, the short distance to the underground goaf allows for uniform mixing without pipe blockage. The high-pressure reinforcement hoppers 10 store the reinforcement material to be added (such as steel fibers, polyethylene fibers, and plant fibers). The capacity of the high-pressure reinforcement hoppers 10 should be sufficient to store the reinforcement material lasting for at least half an hour at the predetermined conveying rate. The high-pressure air input components convey high-pressure air to the high-pressure reinforcement hoppers 10, enabling the transport of reinforcement material into the filling pipeline 30. The high-pressure air also facilitates the uniform mixing of the reinforcement material with the flowing filling slurry, assisting in the case of uneven mixing and layering to improve the workability of the filling slurry.
By setting two sets of high-pressure reinforcement hoppers 10 underground at a distance of 10-15m from the filling discharge port, and supplying them with high-pressure air, the reinforcement material is driven by the high-pressure air into the horizontal filling pipeline 30, and thoroughly mixed with the flowing slurry. This improves the quality of the filling mass, reduces the volume of cement used, and consequently reduces the filling cost.
As shown in Fig. 1, in some embodiments, the feed port 13 is located on the side of the top end of the high-pressure reinforcement hopper 10, and a high-pressure sealing ring 11 is installed at the feed port 13. The high-pressure sealing ring 11 ensures a tight seal of the feed port 13, preventing the leakage of high-pressure air introduced into the high-pressure reinforcement hopper 10. Additionally, a safety valve 12 is installed on the other side of the top end of the high-pressure reinforcement hopper 10, which is pre-set with a high-pressure threshold. When the internal pressure of the high-pressure reinforcement hopper 10 exceeds the set limit, the 6/16 safety valve 12 automatically opens to reduce the pressure, ensuring safety. LU504494
The upper part of the high-pressure reinforcement hopper 10 is cylindrical, while the lower part is cone-shaped to facilitate the discharge of the reinforcement material. Specifically, a bracket 14 is set at the bottom of the high-pressure reinforcement hopper 10 to ensure stable placement on a horizontal surface.
As shown in Fig. 1, in some embodiments, the high-pressure air input components comprise an underground high-pressure air duct 20, a high-pressure air input manifold 40 connected to one end of the underground high-pressure air duct 20, and two sets of high-pressure air input branches 43 connected to the other end of the high-pressure air input manifold 40. The two sets of high-pressure air input branches 43 correspond to the two sets of inlets on the high-pressure reinforcement hoppers 10. The underground high-pressure air duct 20 is horizontally arranged underground, which receives high-pressure air input from a high-pressure pump and a high-pressure air storage tank. The two sets of high-pressure air input branches 43 are connected to the high-pressure air input manifold 40 through T-joints. The two sets of high-pressure air input branches 43 are connected to the respective inlets using clamps.
The high-pressure air input manifold 40 is equipped with an underground high-pressure air valve 41 and a pressure gauge 42. The underground high-pressure air valve 41 controls the air passage between the high-pressure air input manifold 40 and the underground high-pressure air duct 20. The pressure gauge 42 provides real-time readings of the pressure inside the high-pressure air input manifold 40 to ensure that the pressure is 0.1 MPa higher than that in the filling pipeline 30, preventing backflow of the filling slurry. The two sets of high-pressure air input branches 43 are each equipped with a first manual valve 44 and a second manual valve 45, which control the air passage for introducing high-pressure air into the two sets of high-pressure reinforcement hoppers 10.
As shown in Fig. 1, in some embodiments, the discharge port is located at the bottom of the high-pressure reinforcement hopper 10, in an intermediate position. The reinforcement material conveying pipeline comprises two sets of discharge branches 51 connected to the respective discharge ports, and a discharge manifold 50 connected to the other end of the discharge branches 51. The discharge branches 51 and the discharge manifold 50 are connected through 7/16
T-joints, and the discharge branches 51 are clamped to the discharge ports. Both the discharge, 4494 branches 51 and the discharge manifold 50 are made of high-pressure rubber air pipes with strong pressure resistance. Their inner diameter is 5-8 times larger than the maximum length of the reinforcement material to prevent blockage. The other end of the discharge manifold 50 is connected to the filling pipeline 30, and the discharge manifold 50 is made of rubber. The discharge manifold 50 and the filling pipeline 30 are vertically arranged with each other.
The two sets of discharge branches 51 are each equipped with a third manual valve 52 and a fourth manual valve 53, which control the flow of the reinforcement material in the conveying pipeline. The reinforcement material conveying control component and the air-liquid separation air cushion are installed on the discharge manifold 50.
Specifically, the air-liquid separation air cushion is located at the bottom of the discharge manifold 50, preventing backflow of the filling slurry. The air-liquid separation air cushion is a unidirectional high-pressure air cushion installed inside the filling pipeline 30, with a protruding interface. When high-pressure air is supplied, the air cushion opens under pressure, allowing the high-pressure air to transport the reinforcement material into the filling pipeline 30. When the supply of high-pressure air is stopped, the air cushion restores its original shape due to elasticity, preventing backflow of the filling slurry.
The reinforcement material conveying control component comprises an electromagnetic valve 60 set in the middle of the discharge manifold 50, and a control device connected to the electromagnetic valve 60. The control device consists of a control switch 61, a control chip 62, and a power battery 63. The power battery 63 supplies power to the electromagnetic valve 60.
Users can pre-set the switching frequency and time of the electromagnetic valve 60 in the control chip 62 based on the amount of reinforcement material and the actual site conditions to achieve precise feeding.
As shown in Fig. 2, a reinforcing process in the flowing of underground filling slurry, using a reinforcement device in the flowing of underground filling slurry, comprising the following steps:
S1: Install the reinforcement device at a distance of 10-15m from the filling discharge port.
After installation, set the switching frequency and time of the electromagnetic valve 60 in the 8/16 control chip 62 according to the amount of reinforcement material. Then, open the control switch, 504494 61.
In this step, the high-pressure reinforcement hoppers 10 are set underground at a distance of 10-15m to ensure sufficient time for uniform mixing. The filling pipeline 30 has an initial flow velocity, and although the viscosity coefficient increases significantly after adding the reinforcement material, the short distance to the underground goaf allows for uniform mixing without pipe blockage.
S2: Open the feed port 13 of one set of high-pressure reinforcement hoppers 10, and add the reinforcement material. Then close the feed port 13 and tighten the high-pressure sealing ring 11.
After adding the material, open the first manual valve 44 and the third manual valve 52. Then open the underground high-pressure air valve 41, and ensure that the pressure gauge 42 reading is 0.1 MPa higher than the pressure in the filling pipeline 30.
In this step, the added reinforcement material should be sufficient for the supply lasting for at least half an hour.
S3: While the conveying is ongoing from the current set of high-pressure reinforcement hoppers 10, open the feed port 13 of the other set of high-pressure reinforcement hoppers 10, and add the reinforcement material. Then close the feed port 13 and tighten the high-pressure sealing ring 11. Afterwards, when the reinforcement material conveying from the current set of high-pressure reinforcement hoppers 10 is completed, open the second manual valve 45 and the fourth manual valve 53, and close the first manual valve 44 and the third manual valve 52.
In this step, the two sets of high-pressure reinforcement hoppers 10 are used alternately to continuously add reinforcement material into the filling pipeline 30 until the entire filling operation is completed. The volume of the high-pressure reinforcement hoppers 10 need not to be excessively large, thereby facilitating the installation underground.
S4: Repeat steps S1 to S3 until the filling operation is completed. Then, sequentially close the control switch 61, the fourth manual valve 53/third manual valve 52, the second manual valve 45/first manual valve 44, and the underground high-pressure air valve 41.
In this step, the first manual valve 44 and the third manual valve 52 correspond to one set of 9/16 high-pressure reinforcement hoppers 10, while the second manual valve 45 and the fourth 50 4494 manual valve 53 correspond to the other set of high-pressure reinforcement hoppers 10.
Additionally, to prevent the air-liquid separation air cushion from being blocked by the filling slurry, high-pressure air can be introduced for flushing after the filling pipeline cleaning,
