Description

Technical Field

[0001] The present application relates to the field of coal mine safety technology, and in particular to a monitoring method, device, equipment and storage medium for roof fracture type rock burst. Background Art

[0002] Roof fracture type rock burst is a typical type of rock burst that may occur during coal mining. In mines with thick and hard roofs, the roof is hard and not easy to fall off, forming a suspended roof in the goaf. As the working face advances, the area of ​​the suspended roof in the goaf increases. The coal seam roof bends and sinks under the action of its own weight and the load of the overlying rock strata, and a certain tensile stress is generated in the center of the suspended roof in the goaf. Once the tensile strength is reached in a certain part, macro cracks are formed in the roof instantly, and the tensile stress is rapidly transferred, forming an avalanche-like chain reaction. The roof suddenly breaks, and the surrounding rock system becomes unstable as a whole, resulting in roof fracture type rock burst.

[0029] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0030] The following describes the method and device for monitoring roof fracture type rock burst according to an embodiment of the present application with reference to the accompanying drawings.

[0031] Figure 1 1 is a flow chart of a method for monitoring roof fracture type rock burst provided in an embodiment of the present application. Figure 1 As shown, the method may include but is not limited to the following steps:

[0032] Step S101: Obtain the physical and mechanical parameters of the roof and the corresponding stiffness parameters of the roof and the coal seam.

[0033] Among them, the above-mentioned physical and mechanical parameters include at least one of the following: uniformly distributed load value; equivalent shear modulus of the top plate; thickness value of the top plate; shear strength of the top plate.

[0034] It should be noted that the above-mentioned uniformly distributed load value is the uniformly distributed load value obtained by simplifying the deadweight of the roof rock beam and the overlying rock strata, that is, the resultant force of the deadweight of the roof rock beam above the coal seam and goaf and the uniformly distributed load exerted on the overlying rock strata in a certain specific area.

[0035] Among them, the above-mentioned stiffness parameters include at least one of the following: the average softening stiffness value of the roof and the coal seam; the vertical average stiffness value of the roof and the coal seam.

[0036] It should be noted that the average softening stiffness value of the roof and coal seam refers to an indicator of the ability of the rock stratum and coal seam combination to resist deformation, which reflects the degree of deformation and the ability of the rock stratum and coal seam combination to recover to its original state after being subjected to force; the vertical average stiffness value of the coal seam roof and coal seam refers to the ability of the roof and coal seam combination to resist deformation under the pressure of the overlying rock strata.

[0037] As an example, see Figure 2 , Figure 2 Schematic diagram of an elastic-plastic shear beam calculation model provided in an embodiment of the present application. Figure 2 As shown, we can first determine the simplified uniformly distributed load value of the deadweight of the roof rock beam and the overlying rock strata in the coal mine, and then determine the equivalent shear modulus, roof thickness and roof shear strength in turn.

[0038] Step S102: Obtain the peak strength of the coal body of the coal seam.

[0039] For example, a uniaxial compression test may be performed on the coal body of the coal seam to monitor the stress and strain of the coal body specimen in real time, thereby determining the peak strength of the coal body.

[0040] Step S103: Obtain the distance from the peak position of the coal seam advance support pressure to the coal wall.

[0041] For example, the distance from the peak position of the advance support pressure of the coal seam to the coal wall can be determined by performing in-situ testing on the coal seam. For example, monitoring equipment can be arranged in the coal seam to monitor the peak position of the advance support pressure, thereby monitoring and obtaining the distance from the peak position of the advance support pressure of the coal seam to the coal wall.

[0042] Step S104: based on the physical and mechanical parameters of the roof, the stiffness parameters corresponding to the roof and the coal seam, and the peak strength of the coal body of the coal seam, a threshold for distinguishing the occurrence of roof fracture type rock burst is obtained.

[0043] In some embodiments, the following formula can be used to obtain the threshold for determining the occurrence of roof fracture type rock burst based on the physical and mechanical parameters of the roof, the stiffness parameters corresponding to the roof and the coal seam, and the peak strength of the coal body of the coal seam:

[0044]

[0045] Among them, S is the discrimination threshold, q is the uniform load value, G is the equivalent shear modulus of the top plate, H is the thickness of the top plate, τ0 is the shear strength of the top plate, σ c is the peak strength of the coal body, k1 is the average softening stiffness value of the roof and the coal seam, and k is the vertical average stiffness of the roof and the coal seam.

[0046] Step S105: Based on the distance value from the peak position of the coal seam advance support pressure to the coal wall and the discrimination threshold, the roof fracture type rock burst is monitored.

[0047] For example, the probability of roof fracture type rock burst can be determined based on the difference between the distance from the peak position of the coal seam advance support pressure to the coal wall and the discrimination threshold. For example, when the difference is greater than 0, it can be determined that it will definitely occur, when the difference is equal to 0, it can be determined that the critical condition is reached, and when the difference is less than 0, it can be determined that it will not occur.

[0048] By implementing the embodiments of the present application, a discrimination threshold for monitoring roof fracture type impact ground pressure can be obtained based on the physical and mechanical parameters of the roof, the stiffness parameters corresponding to the roof and the coal seam, and the peak strength of the coal body of the coal seam, thereby monitoring the roof fracture type impact ground pressure through the distance from the peak position of the coal seam advance support pressure to the coal wall and the discrimination threshold.

[0049] In some embodiments, the distance from the peak position of the coal seam advance support pressure to the coal wall and the obtained discrimination threshold can be used to determine whether the critical condition for the occurrence of roof fracture type rock burst in the coal mine. Figure 3 , Figure 3 FIG. 1 is a flow chart of another method for monitoring roof fracture type rock burst provided in an embodiment of the present application. Figure 3 As shown, the method may include but is not limited to the following steps:

[0050] Step S301: Obtain the physical and mechanical parameters of the roof and the corresponding stiffness parameters of the roof and the coal seam.

[0051] In the embodiments of the present application, step S301 can be implemented in any of the embodiments of the present application, and the embodiments of the present application do not limit this and will not be described in detail.

[0052] Step S302: Obtain the peak strength of the coal body of the coal seam.

[0053] In the embodiments of the present application, step S302 can be implemented by any of the methods in the embodiments of the present application, and the embodiments of the present application do not limit this and will not be described in detail.

[0054] Step S303: Obtain the distance from the peak position of the coal seam advance support pressure to the coal wall.

[0055] In the embodiments of the present application, step S303 can be implemented by any of the methods in the embodiments of the present application, and the embodiments of the present application do not limit this and will not be described in detail.

[0056] Step S304: based on the physical and mechanical parameters of the roof, the stiffness parameters corresponding to the roof and the coal seam, and the peak strength of the coal body of the coal seam, a threshold for distinguishing the occurrence of roof fracture type rock burst is obtained.

[0057] In the embodiments of the present application, step S304 can be implemented by any of the methods in the embodiments of the present application, and the embodiments of the present application do not limit this and will not be described in detail.

[0058] Step S305: In response to the distance value being equal to the discrimination threshold, determining that a critical condition for roof fracture type rock burst is reached.

[0059] For example, if it is determined that the distance value and the discrimination threshold value satisfy the relationship shown in the following formula, it is determined that the critical condition for the occurrence of roof fracture type rock burst in the coal mine is reached.

[0060]

[0061] Among them, b is the distance from the peak position of the coal seam advance support pressure to the coal wall, and S is the discrimination threshold.

[0062] It can be understood that if the distance value is greater than the discrimination threshold, it can also be determined that the critical condition for the occurrence of roof fracture type rock burst has been reached.

[0063] By implementing the embodiments of the present application, when the distance from the peak position of the coal seam advance support pressure to the coal wall is equal to the discrimination threshold, it can be determined that the critical condition for roof fracture type rock burst occurs, thereby providing an effective early warning for roof fracture type rock burst.

[0066] In an optional implementation, the following formula can be used to obtain the threshold for determining the occurrence of roof fracture type rock burst based on the physical and mechanical parameters of the roof, the stiffness parameters corresponding to the roof and the coal seam, and the peak strength of the coal body of the coal seam:

[0069] In one implementation, the second processing module 405 may be used to: in response to the distance value being equal to the discrimination threshold, determine that a critical condition for the occurrence of roof fracture type rock burst is reached.
