Description

Technical Field

[0001] This invention relates to the field of coal mining technology, and in particular to a method for determining the safe zone for delamination grouting, a storage medium, and an electronic device. Background Technology

[0002] The grouting and backfilling method for coal mining in the abscission zone involves establishing grouting stations and drilling holes in the goaf to inject high-pressure grout into the rock strata in the abscission zone. This fills the abscission space between the rock strata, reducing the subsidence rate of the abscission zone strata and thus minimizing surface subsidence and deformation, which is beneficial for underground mining. Abscission water (hereinafter referred to as abscission water) is a new type of water hazard that gradually forms during the mining of thick coal seams. Abscission water is characterized by its strong concealment and suddenness. During the mining of thick coal seams, the overlying rock strata in the goaf gradually subside. Due to differences in lithology, the subsidence rates of different rock types vary, gradually leading to abscission and the formation of cavities. Simultaneously, the subsided strata generate numerous fissures from bottom to top, extending upwards and penetrating major aquifers such as the Jurassic Zhiluo Formation and the Cretaceous Luohe Formation. Pore water from the sandstone in these aquifers gradually converges into the abscission cavities along these water-conducting fissures. Because mudstone strata have a certain water-retaining effect, water accumulates in the abscission cavities over time, increasing in volume and exerting a stronger force on the underlying rock. As mining activities continue to cause overburden damage, the balance between the gravity of the water in the cavity and the supporting force of the rock strata at the bottom of the cavity is broken. The abscission water then breaks through the weakest point of the rock at the bottom of the cavity and suddenly bursts out, surging from the goaf into the working face (usually from both ends or low-lying areas of the working face), causing a water inrush accident.

[0003] Currently, to protect aquifers, existing technologies for preventing aquifer delamination water involve pre-drainage in coal preparation roadways and drilling straight-through diversion holes from the surface into the aquifer space. However, the inventors discovered during the development of this invention that existing aquifer delamination water prevention measures all rely on on-site construction during coal mining, which can easily lead to water-related accidents. Furthermore, it is impossible to accurately determine the safe zone for aquifer grouting before coal mining, resulting in low safety. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that cannot accurately determine the safety zone for delamination grouting before coal mining, resulting in low safety, and to provide a method, storage medium, and electronic device for determining the safety zone for delamination grouting.

[0005] The technical solution of the present invention provides a method for determining the safe zone of delamination grouting, comprising:

[0009] A physical similarity simulation model of the mining area is established based on the physical and mechanical parameters to obtain the second grouting safety zone. The second grouting safety zone is the distance from the first key layer above the collapse zone to the first key layer below the water-bearing zone in the physical similarity simulation model of the mining area.

[0017] In one of the alternative technical solutions, determining the lower limit of the third grouting safety zone based on the mining height of the working face includes:

[0018] The lower limit of the third grouting safety zone is obtained by calculating the product of the preset constant and the mining height of the working face.

[0019] In one of the alternative technical solutions, the step of calculating the rock strata curvature parameters of the key strata below the aquifer layer layer by layer from the mining face toward the key strata of the aquifer includes:

[0020] The bending parameters of the rock strata are calculated using the following formula:

[0021]

[0022] Where θ is the bending parameter of the rock strata; τ is the shear bearing capacity of the key stratum, τ i The critical layer represents the actual shear force it bears, c represents the cohesion, and σ represents the shear force it bears. a This is the actual normal stress. It is the internal friction angle.

[0023] In one of the alternative technical solutions, determining the upper limit of the third grouting safety zone based on the rock stratum tortuosity parameters includes:

[0024] If the rock stratum bending parameter is less than or equal to the preset parameter, the height of the next critical layer corresponding to the rock stratum bending parameter is taken as the upper limit of the third grouting safety zone.

[0025] In one of the alternative technical solutions, calculating the third grouting safety zone based on the lower limit value and the upper limit value of the third grouting safety zone includes:

[0026] The difference between the upper limit of the third grouting safety zone and the lower limit of the third grouting safety zone is calculated to obtain the third grouting safety zone.

[0028] The minimum value among the first grouting safety zone, the second grouting safety zone, and the third grouting safety zone is set as the target grouting safety zone.

[0029] In one of the alternative technical solutions, the physical and mechanical parameters include strength, compressive strength, cohesion, elastic modulus, and density.

[0040] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0041] It is readily understood that, based on the technical solution of this invention, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of the invention.

[0042] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0043] like Figure 1 As shown, a flowchart of a method for determining the safe zone for delamination grouting according to an embodiment of the present invention is provided, including:

[0044] Step S101: After determining the area to be grouted, collect rock strata samples from each rock stratum in the area to be grouted.

[0045] Step S102: Prepare standard specimens for each rock layer sample and conduct physical experiments on the standard specimens to obtain the corresponding physical and mechanical parameters;

[0046] Step S103: Establish a numerical simulation model of the mining area based on physical and mechanical parameters to obtain the first grouting safety zone. The first grouting safety zone is the distance from the first key layer above the caving zone to the first key layer below the water-bearing zone in the numerical simulation model of the mining area.

[0047] Step S104: Establish a physical similarity simulation model of the mining area based on physical and mechanical parameters to obtain the second grouting safety zone. The second grouting safety zone is the distance from the first key layer above the caving zone to the first key layer below the water-bearing zone in the physical similarity simulation model of the mining area.

[0048] Step S105: Determine the working face mining height and strata curvature parameters in the numerical simulation model or physical similarity simulation model of the mining area, and calculate the third grouting safety zone based on the working face mining height and strata curvature parameters;

[0049] Step S106: Determine the target grouting safety zone based on the first grouting safety zone, the second grouting safety zone, and the third grouting safety zone.

[0050] Specifically, before mining commences, step S101 first determines the grouting area, which is the overlying rock strata above the goaf. Within this area, rock samples are collected from each stratum, for example, at intervals of 50 meters or 100 meters. Next, step S102 prepares each rock sample into a standard specimen and conducts physical experiments on it, such as Brazilian splitting tests, triaxial compression tests, uniaxial compression tests, and seepage tests, to obtain the physical and mechanical parameters of each standard specimen. These parameters include strength, compressive strength, cohesion, elastic modulus, and density. Then, step S103 establishes a numerical simulation model of the mining area based on the physical and mechanical parameters of each standard specimen. This model can be implemented using the Universal Discrete Element Method (UDI). The Code (UDEC) software is used to construct a numerical simulation model of the mining area to simulate the damage to the mining area during mining. Based on the numerical simulation model, a first grouting safety zone is obtained, which is the distance W1 from the first critical layer above the caving zone to the first critical layer below the aquifer in the numerical simulation model. Step S104 is then executed to establish a physical similarity simulation model of the mining area based on the physical and mechanical parameters of each standard specimen. This physical similarity simulation model refers to a scaled-down model of the mining area built in the laboratory based on physical and mechanical parameters. The physical similarity simulation model is used to simulate the damage to the mining area during mining. Based on the physical similarity simulation model, a second grouting safety zone is obtained, which is the distance from the first critical layer above the caving zone to the aquifer in the physical similarity simulation model. The distance to the first critical layer below is W2; then, step S105 is executed to determine the working face mining height h and the stratum curvature parameter θ based on the mining area numerical simulation model or the mining area physical similarity simulation model. The working face mining height h refers to the height at which coal is mined during the mining process, and only one height can be mined at a time. The working face mining height h and the stratum curvature parameter θ are obtained through multiple experiments, and the third grouting safety zone W3 is calculated based on the working face mining height and the stratum curvature parameter; finally, step S106 is executed to determine the target grouting safety zone based on the first grouting safety zone, the second grouting safety zone, and the third grouting safety zone, thereby accurately determining the delamination grouting safety zone before coal mining, protecting the aquifer, preventing damage to the aquifer during coal mining, leading to water hazard accidents, and improving safety.

[0051] In this embodiment, after determining the area to be grouted, rock strata samples are collected from each rock stratum in the area. Each rock stratum sample is made into a corresponding standard specimen, and physical experiments are conducted on the standard specimens to obtain the corresponding physical and mechanical parameters. Based on the physical and mechanical parameters, a numerical simulation model of the mining area or a physical similarity simulation model of the mining area is established to obtain the first grouting safety zone and the second grouting safety zone. The working face mining height and rock strata curvature parameters in the numerical simulation model or the physical similarity simulation model of the mining area are determined, and the third grouting safety zone is calculated based on the working face mining height and rock strata curvature parameters. The target grouting safety zone is determined based on the first grouting safety zone, the second grouting safety zone, and the third grouting safety zone. This allows for the accurate determination of the delamination grouting safety zone before coal mining, protecting the aquifer, preventing damage to the aquifer during coal mining, preventing water hazard accidents, and improving safety.

[0052] In one embodiment, step S106 includes:

[0053] The minimum value among the first grouting safety zone, the second grouting safety zone, and the third grouting safety zone is set as the target grouting safety zone.

[0054] Specifically, to further improve the accuracy of the target grouting safety zone, the target grouting safety zone S is calculated using the following formula:

[0055] S = min(W1, W2, W3)

[0056] Wherein, S is the target grouting safety zone; W1 is the first grouting safety zone; W2 is the second grouting safety zone; and W3 is the third grouting safety zone.

[0057] like Figure 2 As shown, Figure 2 A flowchart of a method for determining a safe zone for delamination grouting, provided in another embodiment of the present invention, includes:

[0058] Step S201: After determining the area to be grouted, collect rock strata samples from each rock stratum in the area to be grouted;

[0059] Step S202: Prepare standard specimens for each rock layer sample and conduct physical experiments on the standard specimens to obtain the corresponding physical and mechanical parameters;

[0060] Step S203: Establish a numerical simulation model of the mining area based on physical and mechanical parameters to obtain the first grouting safety zone;

[0061] Step S204: Establish a physical similarity simulation model of the mining area based on physical and mechanical parameters to obtain the second grouting safety zone;

[0062] Step S205: Determine the working face mining height and strata curvature parameters in the numerical simulation model or physical similarity simulation model of the mining area;

[0063] Step S206: Determine the lower limit of the third grouting safety zone based on the mining height of the working face;

[0064] Step S207: Calculate the rock strata curvature parameters of the key strata below the aquifer layer layer by layer from the mining face toward the key strata of the aquifer.

[0065] Step S208: Determine the upper limit of the third grouting safety zone based on the rock strata bending parameters;

[0066] Step S209: Calculate the third grouting safety zone based on the lower limit and upper limit of the third grouting safety zone;

[0067] Step S210: Determine the target grouting safety zone based on the first grouting safety zone, the second grouting safety zone, and the third grouting safety zone.

[0068] Specifically, based on the above embodiments, the difference in this embodiment is that the lower limit value h1 of the third grouting safety zone is determined according to the mining height of the working face through steps S206 to S209. The rock stratum curvature parameter θ of the key layer below the aquifer is calculated layer by layer from the mining working face to the key layer of the aquifer. The upper limit value h2 of the third grouting safety zone is determined according to the rock stratum curvature parameter θ. The third grouting safety zone W3 is calculated according to the lower limit value h1 and the upper limit value h2 of the third grouting safety zone.

[0069] In this embodiment, the lower limit of the third grouting safety zone is determined based on the mining height of the working face, and the upper limit of the third grouting safety zone is determined based on the rock stratum curvature parameters. The third grouting safety zone is then calculated using the lower and upper limits of the third grouting safety zone, thereby more accurately determining the target grouting safety zone. This enables accurate determination of the delamination grouting safety zone before coal mining, protecting the aquifer, preventing damage to the aquifer during coal mining, preventing water-related accidents, and improving safety.

[0070] In one embodiment, step S206 includes:

[0071] The product of the preset constant and the mining height of the working face is calculated to obtain the lower limit value of the third grouting safety zone.

[0072] Specifically, the preset constant can be set according to user needs. In this embodiment, the preset constant is preferably 5, that is, the lower limit value of the third grouting safety zone h1 = 5h, so as to more accurately determine the mining height of the working face.

[0073] In one embodiment, to more accurately determine the rock stratum bending parameter θ, step S207 includes:

[0074] The rock strata bending parameters are calculated using the following formula:

[0075]

[0076] Where θ is the rock stratum bending parameter; τ is the shear bearing capacity of the key stratum, τ i The critical layer represents the actual shear force it bears, c represents the cohesion, and σ represents the shear force it bears. a This is the actual normal stress. It is the internal friction angle.

[0077] In one embodiment, to obtain the upper limit value of the third grouting safety zone more accurately, step S208 includes:

[0078] If the rock stratum bending parameter is less than or equal to the preset parameter, the height of the next critical layer corresponding to the rock stratum bending parameter will be used as the upper limit of the third grouting safety zone.

[0079] Specifically, the preset parameters can be set according to user needs. In this embodiment, the preset parameter is preferably 1.2. It is determined whether the rock stratum curvature parameter is less than or equal to the preset parameter. If so, it is determined that the key layer below the corresponding aquifer is the key layer outside the grouting safety zone. The height of the upper key layer corresponding to the rock stratum curvature parameter is taken as the upper limit value h2 of the third grouting safety zone.

[0080] In one embodiment, to obtain the third grouting safety zone more accurately, step S209 includes:

[0081] The difference between the upper limit and the lower limit of the third grouting safety zone is calculated to obtain the third grouting safety zone.

[0082] Specifically, the third grouting safety zone W3 is calculated using the following formula:

[0083] W3 = h2 - h1,

[0084] Wherein, W3 is the third grouting safety zone; h2 is the upper limit of the third grouting safety zone; and h1 is the lower limit of the third grouting safety zone.
