As used herein, the terms "first", "second", "third", and "fourth", etc. are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of individual components.

[0054] like Figure 1 As shown, according to an embodiment of the present invention, a method for analyzing the stability of an open-pit mine slope based on multiple monitoring data is provided, comprising the following steps:

[0055] Step S101, obtaining water level data in the slope rock mass, change status of crack expansion in the slope rock mass, data of blasting vibration on the slope rock mass, surface deformation data of the slope rock mass, displacement data of surface monitoring points of the slope rock mass and dynamic data of slope rock mass deformation.

[0056] Step S102, calculating the impact factor w, the impact factor q, the impact factor b, the impact factor g, the impact factor s and the impact factor k.

[0057] Specifically, the influence factor w of the water level in the slope rock body on the slope stability is calculated according to the water level data in the slope rock body, the influence factor q of crack extension on the slope stability is calculated according to the changing state of crack extension in the slope rock body, the influence factor b of blasting vibration on the slope stability is calculated according to the data of blasting vibration received by the slope rock body, the influence factor g of surface point displacement on the slope stability is calculated according to the displacement data of surface monitoring points of the slope rock body, the influence factor s of surface deformation on the slope stability is calculated according to the surface deformation data of the slope rock body, and the influence factor k of the internal deformation of the slope rock body on the slope stability is calculated according to the internal deformation data of the slope rock body.

[0058] Step S103, judging the stability d of the slope rock mass according to the influencing factor w, the influencing factor q, the influencing factor b, the influencing factor g, the influencing factor s and the influencing factor k.

[0059] The above-mentioned method of judging the stability of the slope rock mass based on the influencing factor w, influencing factor q, influencing factor b, influencing factor g, influencing factor s and influencing factor k includes: setting the stability judgment interval of the slope rock mass; calculating the stability factor d of the slope rock mass through the influencing factor w, influencing factor q, influencing factor b, influencing factor g and influencing factor s; judging the stability of the slope rock mass based on the stability judgment interval in which the stability factor d is located.

[0060] The calculation formula for calculating the stability factor d of the slope rock mass through the influence factor w, influence factor q, influence factor b, influence factor g and influence factor s is:

[0061] d=e w·q·b·g·s·k (3).

[0062] According to the calculated slope stability comprehensive evaluation factor d, a more comprehensive evaluation of the slope stability can be made. In order to facilitate a more intuitive evaluation of the slope stability, a four-color judgment interval of the slope stability danger level can be set, that is, Among them, a1, a2, a3, and a4 are adjustment parameters of the comprehensive evaluation factor of slope stability. The specific parameter values ​​need to be selected in combination with the actual conditions of each mine slope. For example, the slope stability danger level can be explained as follows: blue means that the slope is stable and not dangerous; yellow means that the slope is in a critically stable state and generally dangerous; orange means that the slope is unstable and relatively dangerous; red means that the slope is extremely unstable and particularly dangerous.

[0063] In actual application, when the monitoring data of a certain monitoring means is missing, that is to say, one or more of the influencing factors w, q, b, g and s, the missing influencing factors can be replaced by the number 1; when a certain monitoring means is added to obtain data of other dimensions, a stability influencing factor can be determined according to the impact of the monitoring data on stability, and added to the formula of this method to participate in the calculation.

[0064] The calculation of the above-mentioned influencing factors is specifically as follows: calculating the influencing factor w of the water level in the slope rock body on the slope stability according to the water level data in the slope rock body includes: setting a water level meter in the slope rock body; obtaining the potential slip surface elevation data h at the location of the measuring hole of the water level meter in the slope rock body; q ; Get the water level in the slope rock mass monitored by the water level meter as h s ; Obtain the time t of the influence of water level in the water level slope rock body on slope stability w ; Through the potential slip surface elevation data h q , the water level in the slope rock mass is h s , impact time t w Impact factor w.

[0068] The above-mentioned crack meter is an instrument used to record the width of crack opening in the area where cracks have appeared. The size of the crack opening represents the degree to which the landslide body has left the parent rock.

[0069] The above impact factor q calculation formula is:

[0070]

[0071] The influence factor b of blasting vibration on slope stability is calculated based on the data of blasting vibration on the slope rock mass, including: setting a blasting vibration meter on the slope rock mass; obtaining the vibration velocity v of the blasting particle through the blasting vibration meter b , blasting vibration frequency f, blasting vibration duration t b ; Get the maximum blasting vibration velocity allowed by the slope rock mass as v max ; Get the natural frequency of the slope rock mass as f0; According to the maximum blasting vibration velocity v max and the vibration velocity v of the explosion particle b Calculate the blasting vibration velocity influence factor b1; calculate the blasting vibration frequency influence factor b2 according to the blasting vibration frequency f and the natural frequency of the slope rock mass f0; through the influence factor b1, influence factor b2, duration t b Calculate the impact factor b.

[0072] Explosion particle vibration velocity v b It can represent the amount of energy carried by the blasting vibration when it propagates to the monitoring point; the blasting vibration frequency f represents the frequency of the vibration wave when the seismic wave reaches the monitoring position. When the frequency is consistent with the natural frequency of the rock mass, it is easy to cause the same frequency resonance and aggravate the damage of the rock mass; the blasting vibration duration t b It indicates the continuous effect of blasting vibration on the rock mass. Long-term continuous vibration may cause fatigue damage and stress superposition to the rock mass.

[0074]

[0075] The calculation formula of impact factor b2 is:

[0076]

[0077] The calculation formula of impact factor b is:

[0078] b=b1·b2·t b (8).

[0080] in, a0 refers to the initial spatial displacement of the detection point, t i is the monitoring interval between the ith monitoring and the i-1th monitoring. The impact factor g is calculated by the point displacement average velocity v1 and the point displacement average velocity v2.

[0081] The calculation formula of the above impact factor g is: The influence factor g of surface point displacement on slope stability can well reveal the deformation and stability characteristics of the slope in the area where the point is currently located.

[0082] GNSS (Global Navigation Satellite System) or monitoring piles can usually be used to monitor the displacement of slope surface points.

[0083] Calculating the influence factor s of the surface deformation on the slope stability according to the surface deformation data of the slope rock mass includes: setting a radar on the slope rock mass; obtaining the deformation area m and the deformation speed v of the deformation area through the radar; obtaining the maximum allowable deformation area m0 of the slope rock mass and the maximum allowable deformation speed v0 of the slope rock mass; calculating the influence factor s through the deformation area m, the deformation speed v of the deformation area, the maximum deformation area m0 and the maximum deformation speed v0.

[0084] Usually, the internal displacement of the rock mass on the slope of an open-pit mine is monitored by an inclinometer. The core data of the monitoring is the change in the inclination angle, but the final performance data is the horizontal displacement.

[0085] Generally, the equipment used for surface displacement monitoring in open-pit mines is slope radar. Slope radar monitoring technology is a surface monitoring technology. Compared with other point monitoring, it has the characteristics of wider area coverage and overall deformation monitoring.

[0086] The calculation formula of impact factor s is:

[0087]

[0088] Calculating the influence factor k of the internal deformation of the slope rock mass on the slope stability based on the internal deformation data of the slope rock mass includes: obtaining the cumulative displacement of the internal deformation of the slope rock mass monitored for the nth time as m n ; The cumulative displacement of the internal deformation of the slope rock mass monitored for the n-1th time is m n-1 ; Obtain the monitoring interval time t between the nth monitoring of the internal deformation of the slope rock mass and the n-1th monitoring of the internal deformation of the slope rock mass m ; Based on the monitoring interval t m , the cumulative displacement is m n , the cumulative displacement is m n-1 , calculate the average displacement velocity v of the internal deformation of the slope rock mass between the nth monitoring and the n-1th monitoring n , The cumulative displacement based on the internal deformation of the slope rock mass is m n-1 The cumulative monitoring interval of the internal deformation of the slope rock mass is used to calculate the average velocity of the cumulative displacement of the internal deformation of the slope rock mass as v k , t i is the monitoring interval between the i-th monitoring and the i-1-th monitoring; the average displacement speed is v n , the average velocity of the cumulative displacement is v k Calculate the impact factor k:

[0091] The present invention also discloses an electronic device, which includes: a processor and a memory for storing executable instructions of the processor; wherein the processor is configured to execute the above-mentioned analysis method.

[0092] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the present invention performs mathematical regression analysis on a large amount of data monitored in normal times, and inversely calculates the reasonable value range of each parameter in the formula when the slope does not collapse; through the inversion of the collapse case, the monitoring data before the slope collapse is used to obtain the limit data of each parameter in the formula.
