[0002] In the related technology, the upward layered mining method is usually adopted for mining, and before the mining operation, it is usually necessary to excavate a central ventilation pedestrian skylight. However, during the excavation construction of the skylight, it is easy to encounter the situation that the ore body of the skylight working surface is broken and unstable, which can easily cause the skylight working surface structure to become unstable and there is a risk of collapse, which poses certain safety hazards. Moreover, if the skylight with the risk of collapse is not handled safely in time, the skylight collapse will also threaten the lives of the workers in the mining space. Therefore, how to achieve safe handling of the skylight with the risk of collapse has become a research goal of industry insiders. Summary of the invention

[0004] In order to achieve the above-mentioned purpose, the present disclosure provides a filling method for a patio, the filling method comprising: before the working surface structure of the patio becomes unstable but does not collapse, setting a blocking structure at the bottom of the patio to block the bottom of the patio; setting up a filling pipeline and an exhaust pipeline inside the patio; filling the patio in multiple times through the filling pipeline to form a filling structure, and the blocking structure, the filling pipeline and the exhaust pipeline are all connected to the patio through the filling structure.

[0005] Optionally, the skylight is filled multiple times through the filling pipeline to form a filling structure, including: pre-filling part of the space in the skylight through the filling pipeline to form a first filling structure, and the top wall of the sealing structure, the side wall of the filling pipeline and the side wall of the exhaust pipeline are all connected to the skylight through the first filling structure.

[0009] Optionally, the thickness of the second filling structure in the height direction of the patio is 80 cm-120 cm.

[0010] Optionally, after partially filling the space in the skylight for the second time through the filling pipeline to form a second filling structure, the remaining space in the skylight continues to be filled through the filling pipeline until the filling material filled in the skylight overflows from the outlet of the exhaust pipeline, and the filling operation is stopped.

[0011] Optionally, the filling pipeline and the exhaust pipeline are set up inside the patio, comprising: along the height direction of the patio, the filling pipeline and the exhaust pipeline are respectively passed through the blocking structure, so that the filling pipeline has an outlet located in the patio, and an inlet located outside the patio and connected to a filling material supply device, so that the exhaust pipeline has an air inlet located in the patio, and an air outlet located outside the patio; the filling pipeline and the exhaust pipeline are respectively extended to the top wall of the patio, and after the filling pipeline and the exhaust pipeline contact the top wall of the patio, the filling pipeline and the exhaust pipeline are respectively lowered to a preset height, so that there is a gap between the outlet of the filling pipeline and the top wall of the patio, and along the height direction of the patio, the extension length of the exhaust pipeline in the patio is not less than the extension length of the filling pipeline in the patio.

In addition, since the skylight is filled multiple times through the filling pipeline and the gas in the skylight can be discharged to the outside of the skylight through the exhaust pipeline, the filling effect in the skylight can be improved, which helps to make the filling structure saturated with the space in the skylight, increase the connection area between the filling structure and the working surface structure of the skylight, and make the filling structure and the working surface structure of the skylight firmly connected with each other with high reliability, further reducing the possibility of skylight collapse and improving the safety of mining operations in the mining space.

DETAILED DESCRIPTION

[0018] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0019] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0020] In the present disclosure, unless otherwise stated, "inside" and "outside" refer to the inside and outside relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another element and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0021] According to a filling method for a patio provided by the present disclosure, reference is made to Figure 1 and Figure 2 As shown, the filling method includes steps S100 to S300.

[0022] In step S100 , before the working surface structure of the patio 1 becomes unstable and collapses, a blocking structure 2 is provided at the bottom of the patio 1 to block the bottom of the patio 1 .

[0023] In step S200 , a filling pipeline 3 and an exhaust pipeline 4 are installed inside the skylight 1 .

[0024] In step S300 , the skylight 1 is filled multiple times through the filling pipeline 3 to form a filling structure 5 , and the blocking structure 2 , the filling pipeline 3 and the exhaust pipeline 4 are all connected to the skylight 1 through the filling structure 5 .

[0025] Through the above technical solution, that is, the filling method for the patio provided by the present disclosure, first, before the working surface structure of the patio 1 becomes unstable and collapses, a plugging structure 2 is set at the bottom of the patio 1 to block the bottom of the patio 1, and then a filling pipeline 3 and an exhaust pipeline 4 are set up inside the patio 1. Then, the patio 1 with the potential for collapse is filled through the filling pipeline 3 for multiple times to form a filling structure 5 in the patio 1, so that the plugging structure 2, the filling pipeline 3 and the exhaust pipeline 4 are all connected to the patio 1 through the filling structure 5, so as to achieve the re-stabilization of the working surface structure of the patio 1 through the support of the filling structure 5. In this way, the above filling method can achieve the safe treatment of the patio 1 with the potential for collapse, reduce the possibility of collapse of the patio 1, and improve the safety of the mining operation in the mining field space 7. In addition, since the ceiling 1 is filled multiple times through the filling pipeline 3 and the gas in the ceiling 1 can be discharged to the outside of the ceiling 1 through the exhaust pipeline 4, the filling effect of the ceiling 1 can be improved, which helps to make the filling structure 5 saturated with the space in the ceiling 1, and increase the connection area between the filling structure 5 and the working surface structure of the ceiling 1, so that the filling structure 5 and the working surface structure of the ceiling 1 can be stably connected with high reliability, further reducing the possibility of collapse of the ceiling 1 and improving the safety of mining operations in the mining space 7.

[0026] It should be noted that, since the working surface structure of the ceiling 1 is usually formed directly by the ore body 9, the present invention forms a filling structure 5 by filling the ceiling 1 with a potential collapse hazard, so that the filling structure 5 can be connected to the ore body 9 at the working surface of the ceiling 1, so as to achieve the re-stabilization of the working surface of the ceiling 1 (the surface of the ore body 9), reduce the possibility of collapse of the ceiling 1, and improve the safety of the mining operation in the mining space 7.

[0027] In addition, after the skylight 1 with the potential for collapse is safely handled, the on-site personnel can resume the skylight excavation work during the process of recovering in the mining area 7 by using the upward layered mining method. For example, the skylight after filling can be blasted so that the filling structure 5 in the skylight 1 is blasted and collapsed together with the ore body 9, and the collapsed filling structure 5 can also be used for laying the mining area concrete false bottom 12 at the bottom of the mining area 7, reducing the possibility of ground collapse in the mining area 7, and helping to ensure the safety and stability of operations in the mining area 7. In addition, the collapsed ore body 9 can also be collected and transported through, for example, the mining area ore chute 10 and the bottom tunnel 11 of the ore block in the mining area 7, wherein the specific structures of the ore chute 10 and the bottom tunnel 11 of the ore block can be adaptively designed by those skilled in the art according to actual application requirements, and the present disclosure does not make specific limitations on this.

[0028] Among them, the filling structure 5 can be formed by a filling material filled into the ceiling 1 through the filling pipeline 3. By way of example, the filling material can include, for example, concrete or foamed concrete. In this way, by using concrete or foamed concrete as the filling material, since concrete or foamed concrete has the advantages of strong bearing capacity and good durability, a stable connection can be formed between the filling structure 5 formed by the filling material and the working surface structure of the ceiling 1, which has high reliability, helps to reduce the possibility of collapse of the ceiling 1, and improves the safety of mining operations in the mining space 7.

[0029] In addition, in some embodiments, in order to ensure that the sealing structure 2, the filling pipeline 3 and the exhaust pipeline 4 are all firmly connected to the skylight 1 through the filling structure 5, the connection strength between the filling structure 5 and the sealing structure 2, the filling pipeline 3, the exhaust pipeline 4 and the skylight 1 is not less than 1 MPa, with high reliability, reducing the possibility of collapse of the skylight 1 and improving the safety of mining operations in the mining space 7.

[0030] In addition, the present disclosure does not specifically limit the specific structure of the above-mentioned blocking structure 2 and the sealing connection method between the blocking structure 2 and the bottom of the patio 1. Those skilled in the art can adaptively design it according to actual application requirements. For example, before the working surface structure of the patio 1 becomes unstable and collapses, on-site operators can form the above-mentioned blocking structure 2 by supporting a safety shed at the bottom of the patio 1 or by supporting a retaining wall at the bottom of the patio 1, and can take sealing measures at the connection between the blocking structure 2 and the bottom of the patio 1. The purpose is to achieve the purpose of blocking the bottom of the patio 1 and avoiding leakage of the filling material during subsequent filling operations in the patio 1.

[0031] In step S200, that is, setting up the filling pipeline 3 and the exhaust pipeline 4 inside the skylight 1 may include: for example, after sealing and preventing leakage at the bottom of the skylight 1, the on-site operator may set up the filling pipeline 3 and the exhaust pipeline 4 along the height direction of the skylight 1 (refer to Figure 1In the upper and lower directions of the middle figure), the filling pipeline 3 and the exhaust pipeline 4 are respectively penetrated into the blocking structure 2, so that the filling pipeline 3 has an outlet 310 located in the ceiling 1, and an inlet 320 located outside the ceiling 1 and connected to the filling material supply device (not shown), and the exhaust pipeline 4 has an air inlet 420 located in the ceiling 1, and an air outlet 410 located outside the ceiling 1, so as to achieve the purpose of filling the ceiling 1 through the filling pipeline 3 in multiple times, and discharging the gas in the ceiling 1 to the outside of the ceiling 1 through the exhaust pipeline 4, thereby improving the filling effect in the ceiling 1, helping to make the filling structure 5 saturatedly fill the space in the ceiling 1, and increasing the connection area between the filling structure 5 and the working surface structure of the ceiling 1, so that the filling structure 5 and the working surface structure of the ceiling 1 can be stably connected with each other, with high reliability, further reducing the possibility of collapse of the ceiling 1, and improving the safety of the mining operation in the mining field space 7.

[0032] It should be noted that the present disclosure does not specifically limit the specific structure of the above-mentioned filling material supply device, and its purpose is to be able to communicate between the filling material supply device and the inlet 320 of the filling pipeline 3 through the material delivery pipeline 8 to realize the supply of filling materials such as concrete or foam concrete. In addition, the above-mentioned filling pipeline 3 and exhaust pipeline 4 can be constructed as pipelines of metal materials such as galvanized steel pipes or stainless steel pipes to ensure that the filling pipeline 3 and the exhaust pipeline 4 have high structural strength and corrosion resistance, so as to facilitate the filling operation in the patio 1.

[0033] In addition, the filling pipeline 3 and the exhaust pipeline 4 can be formed by splicing multiple pipelines according to the depth dimension of the patio 1 (the depth of the patio 1 along the height direction), or can also be a whole pipeline, which is not specifically limited in the present disclosure. Moreover, after the filling pipeline 3 and the exhaust pipeline 4 are passed through the plugging structure 2 and erected in the patio 1, the connection points between the filling pipeline 3 and the exhaust pipeline 4 and the plugging structure 2 can be treated to prevent leakage, so as to ensure a high sealing effect.

[0034] In addition, in order to ensure that the filling material can flow out of the filling pipe 3 stably and the gas in the patio 1 can be discharged from the exhaust pipe 4 stably to the outside of the patio 1, in some embodiments, Figure 1 As shown, the on-site operator can extend the filling pipeline 3 and the exhaust pipeline 4 to the top wall 110 of the ceiling 1 respectively, and after the filling pipeline 3 and the exhaust pipeline 4 contact the top wall 110 of the ceiling 1, respectively lower the filling pipeline 3 and the exhaust pipeline 4 to a preset height so that there is a gap between the outlet 310 of the filling pipeline 3 and the top wall 110 of the ceiling 1 (the distance between the outlet 310 of the filling pipeline 3 and the top wall 110 of the ceiling 1 along the height direction of the ceiling 1). This operation is performed so that the filling material can flow out of the filling pipeline 3 stably.

[0035] In addition, along the height direction of the patio 1, the extension length of the exhaust pipe 4 in the patio 1 is not less than the extension length of the filling pipe 3 in the patio 1, that is, it can be understood that after the exhaust pipe 4 and the filling pipe 3 are sent into the patio 1 along the height direction of the patio 1, the position of the air inlet 420 of the exhaust pipe 4 in the patio 1 can be arranged flush with the position of the outlet 310 of the filling pipe 3 in the patio 1, or the position of the air inlet 420 of the exhaust pipe 4 in the patio 1 can be higher than the position of the outlet 310 of the filling pipe 3 in the patio 1. The arrangement can allow the filling material to flow out stably from the filling pipeline 3, and can also allow the gas in the ceiling 1 to be discharged stably from the exhaust pipeline 4 to the outside of the ceiling 1, thereby improving the filling effect in the ceiling 1, helping the filling structure 5 to saturate the space in the ceiling 1, and increasing the connection area between the filling structure 5 and the working surface structure of the ceiling 1, so that the filling structure 5 and the working surface structure of the ceiling 1 can be stably connected with each other with high reliability, further reducing the possibility of collapse of the ceiling 1, and improving the safety of the mining operation in the mining field space 7.

[0036] It should be noted that in order to ensure that the extension length of the exhaust pipe 4 in the ceiling 1 is not less than the extension length of the filling pipe 3 in the ceiling 1, the on-site operator can design the pipe lengths of the exhaust pipe 4 and the filling pipe 3 according to the depth dimension of the ceiling 1 with the risk of collapse (the depth of the ceiling 1 along the height direction). In this way, after the on-site operator sends the exhaust pipe 4 and the filling pipe 3 into the ceiling 1 along the height direction of the ceiling 1, the operator can, for example, obtain the extension lengths of the exhaust pipe 4 and the filling pipe 3 respectively located in the ceiling 1 based on the lengths of the exhaust pipe 4 and the filling pipe 3 outside the ceiling 1 and the thickness of the sealing structure 2 along the height direction of the ceiling 1, so as to achieve the purpose of ensuring that the extension length of the exhaust pipe 4 in the ceiling 1 is not less than the extension length of the filling pipe 3 in the ceiling 1.

[0037] Exemplarily, the above-mentioned gap can be, for example, 10mm-15mm, but the present disclosure is not limited thereto. Its purpose is to enable the filling material to flow out of the filling pipe 3 stably, and to enable the gas in the ceiling 1 to be discharged stably from the exhaust pipe 4 to the outside of the ceiling 1. Those skilled in the art can adaptively design the specific size of the gap according to actual application requirements.

[0038] In step S300, that is, filling the ceiling 1 multiple times through the filling pipeline 3 to form a filling structure 5 may include: for example, after setting up the filling pipeline 3 and the exhaust pipeline 4 inside the ceiling 1, the on-site operator can pre-fill part of the space inside the ceiling 1 through the filling pipeline 3 to form a first filling structure 510, and the top wall of the sealing structure 2, the side wall of the filling pipeline 3 and the side wall of the exhaust pipeline 4 are all connected to the ceiling 1 through the first filling structure 510. In this way, the gap at the top wall of the sealing structure 2 can be pre-sealed in advance by the first filling structure 510, so as to achieve the purpose of completely blocking the bottom of the ceiling 1 and the sealing structure 2 through the first filling structure 510, while ensuring that the bottom of the ceiling 1 and the sealing structure 2 have a high degree of airtightness, the first filling structure 510 can also be used to achieve preliminary fixation of the sealing structure 2, the filling pipeline 3 and the exhaust pipeline 4, so as to facilitate the subsequent filling operation.

[0039] Among them, it should be noted that when pre-filling part of the space in the ceiling 1 through the filling pipeline 3, the filled filling material accumulates to the bottom of the ceiling 1 under the action of gravity to form a first filling structure 510. Exemplarily, the thickness dimension a of the first filling structure 510 in the height direction of the ceiling 1 can be, for example, 20cm-50cm, so as to achieve the purpose of completely blocking the bottom of the ceiling 1 and the sealing structure 2 through the first filling structure 510, avoiding the problem of leakage of the filling material, and also realizing the preliminary fixation of the sealing structure 2, the filling pipeline 3 and the exhaust pipeline 4, so as to facilitate the subsequent filling operation.

[0040] In addition, in some embodiments, Figure 1 As shown, after pre-filling part of the space in the ceiling 1 through the filling pipe 3 to form a first filling structure 510, part of the space in the ceiling 1 is re-filled through the filling pipe 3 to form a second filling structure 520. In this way, the structural strength can be increased by the second filling structure 520, and the possibility of collapse and leakage during subsequent large-scale filling can be reduced, which helps to ensure a stable connection between the filling structure 5 and the working surface structure of the ceiling 1, with high reliability.

[0041] Among them, when filling part of the space in the ceiling 1 for the second time through the filling pipeline 3, the thickness dimension b of the second filling structure 520 in the height direction of the ceiling 1 can be, for example, 80cm-120cm, so as to increase the structural strength through the second filling structure 520 and reduce the possibility of collapse and leakage during subsequent large-scale filling.

[0042] In addition, in some embodiments, reference Figure 1As shown, before the partial space in the skylight 1 is filled for the second time through the filling pipeline 3 and after the first filling structure 510 is formed, a column support 6 can be set on the bottom wall of the blocking structure 2, so that the bottom of the blocking structure 2 can be supported by the column support 6, thereby enhancing the connection reliability of the connection between the blocking structure 2 and the bottom of the skylight 1 and reducing the possibility of collapse and leakage during subsequent large-scale filling.

[0043] Among them, the present disclosure does not specifically limit the specific structure of the above-mentioned column support 6. Those skilled in the art can select any known column structure in the field to support the bottom of the plugging structure 2 according to actual application requirements. The purpose is to enhance the connection reliability of the connection between the plugging structure 2 and the bottom of the patio 1, and reduce the possibility of collapse and leakage during subsequent large-scale filling.

[0044] In addition, in some embodiments, after partial space in the ceiling 1 is filled for the second time through the filling pipeline 3 to form a second filling structure 520, the remaining space in the ceiling 1 is continued to be filled through the filling pipeline 3 until the filling material in the ceiling 1 overflows from the outlet 410 of the exhaust pipeline 4, and the filling operation is stopped. This operation is performed to achieve saturated filling of the filling material in the ceiling 1, so that the filling structure 5 and the working surface structure of the ceiling 1 can be stably connected, thereby reducing the possibility of collapse of the ceiling 1 and improving the safety of the mining operation in the mining field space 7.

[0045] Among them, it should be noted that the present disclosure does not make any specific limitation on the total number of filling times. For example, the total number of filling times can be three times, four times or five times, etc., and the present disclosure does not make any specific limitation on filling the ceiling 1 several times to form the first filling structure 510, filling the ceiling 1 several times to form the second filling structure 520, and filling the remaining space in the ceiling 1 several times until the ceiling 1 is full. Those skilled in the art can adaptively adjust according to actual needs. The purpose is to achieve saturated filling of the filling material in the ceiling 1 so that the filling structure 5 can be firmly connected to the working surface structure of the ceiling 1.

[0046] In addition, after the filling material overflows from the air outlet 410 of the exhaust pipe 4, the on-site operator can use a plugging member (not shown) to block the air outlet 410 of the exhaust pipe 4 to prevent the filling material from leaking and affecting the filling effect of the ceiling 1. The present disclosure does not specifically limit the specific structure of the plugging member, and those skilled in the art can select any well-known plugging block or plugging member in the art to seal the air outlet 410 of the exhaust pipe 4 according to actual application requirements.

[0047] In addition, the thickness dimension a of the first filling structure 510 in the height direction of the ceiling 1 and the thickness dimension b of the second filling structure 520 in the height direction of the ceiling 1 are exemplary. Those skilled in the art can adaptively adjust the thickness dimension a of the first filling structure 510 in the height direction of the ceiling 1 and the thickness dimension b of the second filling structure 520 in the height direction of the ceiling 1 according to actual needs. The purpose is to achieve saturated filling of the filling material in the ceiling 1 so that the filling structure 5 can be firmly connected to the working surface structure of the ceiling 1.
