[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0015] Please refer to Figure 1 As shown, a method for automatically extracting the deformation aggregation area of an open-pit coal mine slope includes Step 1, slope identification and analysis: perform corresponding data collection on the open-pit coal mine, and then identify each slope area corresponding to the open-pit coal mine.

[0016] It should be noted that the measurement technologies include but are not limited to lidar technology and optical measurement technology.

[0017] As an optional implementation manner, the corresponding data collection on the open-pit coal mine is specifically carried out as follows: use the measurement technology to perform comprehensive collection on the open-pit coal mine, and then obtain the point cloud data of each collection surface corresponding to the open-pit coal mine, and establish a model for the point cloud data of each collection surface corresponding to the open-pit coal mine. By using three-dimensional model technology, establish a three-dimensional model corresponding to the open-pit coal mine, and extract the three-dimensional data corresponding to each collection surface from the three-dimensional model, where the three-dimensional data includes tilt angle, depth, and concavity and convexity, so as to complete the corresponding data collection on the open-pit coal mine.

[0018] As an alternative implementation, the specific process of identifying each slope area corresponding to the open-pit coal mine is as follows: Compare the inclination angles of each collection surface corresponding to the open-pit coal mine with the slope reference inclination angle range stored in the database. At the same time, also compare the depth and concavity-convexity of each collection surface corresponding to the open-pit coal mine with the slope reference depth range and slope reference concavity-convexity range stored in the database. If the inclination angle of a certain collection surface corresponding to the open-pit coal mine is within the slope reference inclination angle range stored in the database, and the depth and concavity-convexity of this collection surface corresponding to the open-pit coal mine are within the slope reference depth range and slope reference concavity-convexity range stored in the database, then determine that this collection surface is the slope area corresponding to the open-pit coal mine. By analogy, identify each slope area corresponding to the open-pit coal mine.

[0019] It should be noted that based on the slope numerical values of the current existing data, the slope reference inclination angle range, slope reference depth range, and slope reference concavity-convexity range are obtained.

[0020] Step 2: Screening and determination of the fusion area: Monitor each slope area corresponding to the open-pit coal mine, and then calculate the foundation numerical values of each slope area corresponding to the open-pit coal mine to determine each deformation aggregation area corresponding to the open-pit coal mine.

[0021] It should be noted that the deformation threshold range is [-150, 150], which is set by coal mine professional and technical personnel. Obtain the deformation results of each historical deformation monitoring data corresponding to each slope area of the open-pit coal mine. When the result corresponding to a certain historical deformation monitoring data is that the coal mine slope has deformation, then record the numerical value corresponding to this data as the deformation reference numerical value. In this way, obtain each reference numerical value, and sort each reference numerical value in descending order. Set the minimum and maximum values corresponding to the reference numerical values as the deformation threshold range.

[0022] It should be noted that the ground-based radar technology is the ground-based InSAR technology.

[0023] As an alternative implementation, the specific monitoring process of monitoring each slope area corresponding to the open-pit coal mine is as follows: Use the ground-based radar technology to monitor each slope area corresponding to the open-pit coal mine, and then monitor and obtain the ground images of each slope area corresponding to the open-pit coal mine, and extract radar data from the ground images corresponding to each slope area. The radar data includes longitude, latitude, and deformation values, and perform data processing on the extracted radar data. By cleaning and removing the data with missing longitude or latitude coordinates in the radar data, the standardized radar data is obtained, thus completing the monitoring of each slope area corresponding to the open-pit coal mine.

[0024] As an alternative implementation, the specific calculation process of calculating the foundation numerical values of each slope area corresponding to the open-pit coal mine is as follows: Through the calculation formula:

[0025] Calculate the foundation value β of the i-th slope area corresponding to the open-pit coal mine i , where i is the number of each slope area, i = 1, 2,......, x, and i is any integer greater than 2 is the set reference longitude, and μ′ is the set reference latitude is the set reference deformation value is the longitude of the i-th slope area corresponding to the open-pit coal mine, μ i is the latitude of the i-th slope area corresponding to the open-pit coal mine is the deformation value of the i-th slope area corresponding to the open-pit coal mine, s 1 s 2 and s 3 are the weight factors of the set longitude, the weight factor of the latitude, and the weight factor of the deformation value respectively. 0 < s 1 < 1, 0 < s 2 < 1, 0 < s 3 < 1

[0026] It should be noted that the historical collected longitudes of each slope area corresponding to the open-pit coal mine are obtained from the database, averaged, and then the historical average longitudes are obtained, and the historical average longitudes are used as the reference longitudes. The historical collected latitudes of each slope area corresponding to the open-pit coal mine are obtained from the database, averaged, and then the historical average latitudes are obtained, and the historical average latitudes are used as the reference latitudes. The historical deformation values of each slope area corresponding to the open-pit coal mine are obtained from the database, averaged, and then the historical average deformation values are obtained, and the historical average deformation values are used as the reference deformation values

[0027] It should also be noted that the weight factors of the longitude, the weight factor of the latitude, and the weight factor of the deformation value are obtained through factor analysis. First, the information of the longitude, latitude, and deformation value is condensed, then the corresponding variance interpretation rate is obtained, and then the corresponding weight is obtained by dividing by the variance interpretation rate

[0028] It should be noted again that information condensation refers to condensing multiple analysis items into several key summary indicators. The variance interpretation rate refers to the contribution degree of each principal component or factor to the total variance, usually expressed as a percentage, indicating how much information of the original data is contained in the factor

[0029] As an alternative implementation, the process of determining each deformation aggregation area corresponding to the open-pit coal mine is as follows: Compare the measurement values of each slope area corresponding to the open-pit coal mine with the preset slope deformation threshold range. If the measurement value of a certain slope area corresponding to the open-pit coal mine is not within the preset slope deformation threshold range, it is determined that this slope area has not undergone deformation and does not belong to the deformation aggregation area. If the measurement value of a certain slope area corresponding to the open-pit coal mine is within the preset slope deformation threshold range, it is determined that this slope area has a tendency to deform. By analogy, each deformation aggregation area corresponding to the open-pit coal mine is determined.

[0030] Step 3: Prediction of the state of the fusion area: Extract the characteristics of the deformation aggregation area corresponding to the open-pit coal mine, and then screen to obtain the deformation aggregation area corresponding to the open-pit coal mine, and collect information on the deformation aggregation area corresponding to the open-pit coal mine to predict the state of the deformation aggregation area corresponding to the open-pit coal mine.

[0031] As an alternative implementation, the process of extracting the characteristics of the deformation aggregation area corresponding to the open-pit coal mine is as follows: Extract from the ground-based image the radar as p 0 , the plane of the slope is determined by points A, B, and C, p 1 is a point on the slope plane, and the radial displacement is Then calculate The coordinates in the earth coordinate system and the slope coordinate system.

[0032] By setting p 0 = (x 0 , y 0 , z 0 ), p 1 = (x 1 , y 1 , z 1 ), A = (x A , y A , z A ), B = (x B , y B , z B ), C = (x C , y C , z C ).

[0033] Determine that the equation of the slope ABC is set as ax + by + cz + d = 0, and we know that:

[0034] a = (y B - y A )(z C - z A ) - (y c - y A )(z B - yA )

[0035] b = (z B - z A )(x C - x A ) - (x C - x A )(x B - c A )

[0036] c = (x B - x A )(y C - y A ) - (x c - x A )(y B - y A )

[0037] Thus, a coordinate system is established on the inclined plane:

[0038]

[0039] where is the direction along the upward slope, is the horizontal direction on the slope, is the normal direction.

[0040] Since is in the same direction as , it is easy to know that:

[0041]

[0042] The calculated coordinates in the Earth coordinate system.

[0043] where is a set of standard orthogonal systems. Therefore the coordinate decomposition in the inclined plane system is:

[0044] where · represents the standard inner product of vectors. Furthermore, the calculated coordinates in the inclined plane system are Based on the above coordinates in the Earth coordinate system, the measured values corresponding to the radial deformation in the foundation image are extracted and calculated, and the feature extraction of the deformation aggregation area corresponding to the open-pit coal mine is completed.

[0045] As an optional implementation method, the screening obtains the deformation clustering area corresponding to the open-pit coal mine, and the specific screening process is as follows: the measured values ​​of each deformation clustering area corresponding to the open-pit coal mine are compared with the reference characteristic value interval corresponding to the preset deformation clustering area. If the measured value of a certain deformation clustering area corresponding to the open-pit coal mine is not within the reference characteristic value interval corresponding to the preset deformation clustering area, then the deformation clustering area corresponding to the open-pit coal mine has not developed into a deformation clustering area. If the measured value of a certain deformation clustering area corresponding to the open-pit coal mine is within the reference characteristic value interval corresponding to the preset deformation clustering area, then the deformation clustering area corresponding to the open-pit coal mine is recorded as the deformation clustering area, and so on to obtain the deformation clustering area corresponding to the open-pit coal mine.

[0046] It should be noted that the reference characteristic value range is set by professional and technical personnel in coal mines.

[0047] As an optional implementation method, the state of the deformation concentration area corresponding to the open-pit coal mine is predicted, and the specific prediction process is as follows: using ground-based radar technology to perform monitoring of the deformation concentration area corresponding to the open-pit coal mine in each time period, and then collecting deformation images of the deformation concentration area corresponding to the open-pit coal mine in each time period, and extracting the deformation data of the deformation concentration area corresponding to the open-pit coal mine from the deformation image, and performing normalization processing on the extracted deformation data, wherein the deformation data includes phase difference, dynamic deformation rate, deformation direction and uplift.

[0048] Select the corresponding prediction model, import the deformation data of each time period of the deformation concentration area corresponding to the open-pit coal mine into the prediction model, and calculate the deformation trend assessment coefficient of the deformation concentration area corresponding to the open-pit coal mine. If the output result of the deformation trend assessment coefficient prediction result of the deformation concentration area corresponding to the open-pit coal mine is 1, it is judged that the state of the deformation concentration area corresponding to the open-pit coal mine is dangerous, and corresponding manual intervention prevention is required. If the output result of the deformation trend assessment coefficient prediction result of the deformation concentration area corresponding to the open-pit coal mine is 0, it is judged that the state of the deformation concentration area corresponding to the open-pit coal mine is safe, and the ground-based radar technology continues to monitor the deformation concentration area corresponding to the open-pit coal mine, so as to predict the state of the deformation concentration area corresponding to the open-pit coal mine.

[0049] As an optional implementation, the deformation trend assessment coefficient of the open-pit coal mine corresponding to the deformation concentration area is obtained by calculation. The specific calculation process is as follows: by the calculation formula:

[0050] The deformation trend assessment coefficient δ of the deformation concentration area corresponding to the open-pit coal mine is calculated, where y is the number of each time period, y = 1, 2, ..., b, b is any integer greater than 2, θ y is the phase difference of the yth time period in the open-pit coal mine corresponding to the deformation concentration area, F y is the dynamic deformation rate of the open-pit coal mine corresponding to the deformation concentration area in the yth time period, Gy is the deformation orientation of the y-th time period corresponding to the deformation aggregation area of the open-pit coal mine, Z y is the deformation orientation of the y-th time period corresponding to the deformation aggregation area of the open-pit coal mine, a 1 , a 2 , a 3 and a 4 are respectively the weight factors of the set phase difference, the weight factor of the dynamic deformation rate, the weight factor of the deformation orientation, and the weight factor of the uplift degree, 0 < a 1 <1, 0 < a 2 <1, 0 < a 3 <1, 0 < a 4 <1, ψ is the reference deformation evaluation coefficient.

[0051] It should be noted that the corresponding prediction model is selected: based on the deformation data of the deformation aggregation area corresponding to the open-pit coal mine, the required deformation judgment features of the deformation aggregation area corresponding to the open-pit coal mine are extracted, and the required deformation judgment features of the deformation aggregation area corresponding to the open-pit coal mine are compared with the feature sets corresponding to each prediction model. If the required deformation judgment features of the deformation aggregation area corresponding to the open-pit coal mine are within the feature set corresponding to a certain prediction model, then this prediction model is used as the prediction model for predicting the state of the deformation aggregation area corresponding to the open-pit coal mine.

[0052] It should be noted that the deformation orientation refers to vertical or horizontal. Each historical deformation evaluation coefficient of the deformation aggregation area corresponding to the open-pit coal mine is obtained from the database, and each historical deformation evaluation coefficient is substituted into the average value calculation formula to obtain the average deformation evaluation coefficient, and the average deformation evaluation coefficient is used as the reference deformation evaluation coefficient.

[0053] It should also be noted that the weight factors of the phase difference, the weight factor of the dynamic deformation rate, the weight factor of the deformation orientation, and the weight factor of the uplift degree are obtained through factor analysis. First, the information of the phase difference, the dynamic deformation rate, the deformation orientation, and the uplift degree is condensed, and then the corresponding variance interpretation rate is obtained, and then the corresponding weight is obtained by dividing by the variance interpretation rate.

[0054] In the prediction of the state of the fusion area, the present invention deeply extracts the features of the deformation aggregation area corresponding to the open-pit coal mine, and then screens out the deformation aggregation area corresponding to the open-pit coal mine, and predicts the state of the deformation aggregation area corresponding to the open-pit coal mine, so as to realize the comprehensive monitoring and analysis of the deformation aggregation area corresponding to the open-pit coal mine slope, and further better ensure the application safety corresponding to the open-pit coal mine, realize the detailed analysis of the deformation of the open-pit coal mine slope, so as to obtain accurate state prediction results, and thus implement efficient prevention of geological risks of the deformation of the open-pit coal mine slope.

[0055] Step Four: Result display: Display the state of the deformation aggregation area corresponding to the open-pit coal mine.

[0056] In an embodiment of the present invention, by identifying each slope area corresponding to an open-pit coal mine, and then performing monitoring on each slope area corresponding to the open-pit coal mine, each deformation aggregation area corresponding to the open-pit coal mine is determined, feature extraction is performed on the deformation aggregation area corresponding to the open-pit coal mine, the deformation aggregation area corresponding to the open-pit coal mine is screened, the state of the deformation aggregation area corresponding to the open-pit coal mine is predicted, high-precision monitoring of the deformation aggregation area of the slope of the open-pit coal mine is realized by using the ground-based InSAR technology, so as to efficiently understand the geological state of the deformation aggregation area of the slope of the open-pit coal mine, thereby realizing efficient geological risk prevention, reducing the probability and danger of risk occurrence, solving the deficiencies existing in the current technology. At the same time, the ground-based InSAR technology has the advantages of high spatio-temporal resolution, can realize the minute-level change of the deformation area of the open-pit coal mine monitoring, so as to predict a more accurate state result of the deformation aggregation area corresponding to the slope of the open-pit coal mine, realize more comprehensive protection of the safety of the mining area corresponding to the open-pit coal mine, ensure the safe operation of the mine, and also improve the convenience and efficiency of monitoring the deformation aggregation area of the slope of the open-pit coal mine to a certain extent, reduce the manual monitoring cost, and comprehensively and efficiently guarantee the safety of the open-pit coal mine.
