Mineral resources are important raw materials for the construction of large-scale infrastructure such as roads, bridges, and railways. The existence of mining provides the necessary resource support for these construction projects. As mining activities continue to deepen, the stability of the roadway is crucial to the safe production during the mining process. In the safe production process of mining, roadway stability monitoring is the core link to prevent roof accidents and ensure mining safety. The existing technology has the following main shortcomings: First, the data collection dimension is single, and most systems only focus on the independent monitoring of support structure stress or tunnel displacement, and lack the coordinated analysis of equipment operating conditions and surrounding rock deformation; second, the evaluation model is static, and the dynamic control method is not used to establish a real-time parameter response mechanism; it is impossible to establish a full-domain perception system covering equipment, environment, and structure, which makes it difficult to meet the needs of modern mines for real-time risk warnings, increasing safety risks in the mining process.
[0003] In order to solve the problems raised in this background technology, the present application designs a method and system for analyzing factors affecting tunnel deformation based on data monitoring. Summary of the Invention

[0005] To solve the above technical problems, the present invention adopts the following technical solution: This application provides a method for analyzing factors affecting roadway deformation based on data monitoring, which includes the following specific steps: S1. Acquire mining equipment operation data, support structure status data, and mining tunnel status data; S2. Evaluate the stability of the surrounding rock of the roadway based on the operating data of the mining equipment and the status data of the support structure; S3.

Conduct a roadway deformation risk assessment based on the roadway surrounding rock stability assessment results and the adjacent roadway impact assessment results, and issue a roadway deformation risk warning based on the roadway deformation risk assessment results.
[0006] It should be noted that, as a preferred technical solution for the method for analyzing factors affecting roadway deformation based on data monitoring, the specific steps of S1 are: S11.

Obtain the dynamic load influence assessment value and support structure deformation assessment value results corresponding to each sampling point of the tunnel surrounding rock, and obtain the stability assessment value corresponding to each sampling point of the tunnel surrounding rock by weighted addition of the dynamic load influence assessment value and support structure deformation assessment value corresponding to each sampling point of the tunnel surrounding rock. It should be noted that the dynamic load influence assessment value is a characterization of the equivalent dynamic load strength caused by the mining equipment on the tunnel during mining, and the support structure deformation assessment value is a factor for analyzing whether the support structure will cause excessive deformation and affect the safety of the tunnel. Therefore, by comprehensively considering the equivalent dynamic load strength caused by the mining equipment on the tunnel during mining and whether the support structure will cause excessive deformation, the stability corresponding to each sampling point of the tunnel surrounding rock is assessed, thereby improving the accuracy of the stability assessment value. S24. The stability assessment value of the tunnel surrounding rock is obtained by summing up the stability assessment values corresponding to each sampling point and then averaging them. It should be noted that by summing up the stability assessment values corresponding to each sampling point of the tunnel surrounding rock and then averaging them, the stability assessment values corresponding to different sampling points can be comprehensively evaluated, and the stability assessment values corresponding to each sampling point can be fully considered, avoiding focusing on the stability assessment value corresponding to a single sampling point and ignoring the stability assessment values corresponding to other sampling points, thereby improving the accuracy of the stability assessment value of the tunnel surrounding rock.
[0008] It should be noted that, as a preferred technical solution for the method for analyzing factors affecting roadway deformation based on data monitoring, the specific step of S21 is: performing a dynamic load influence assessment based on the load data of each sampling point applied by the mining equipment on the roadway surrounding rock and the vibration angular frequency data of the mining equipment, wherein the dynamic load influence assessment calculation formula of each sampling point on the roadway surrounding rock is: , where i is the number corresponding to each sampling point on the surrounding rock of the roadway, i is any item from 1 to N, T is the operation cycle of the mining equipment, is the dynamic load data at time t corresponding to the i-th collection point on the surrounding rock of the roadway, is the reference load data corresponding to the i-th collection point on the surrounding rock of the roadway, is the attenuation coefficient of the roadway rock mass, is the vibration angular frequency of the mining equipment during operation, is the critical frequency of the roadway rock mass. It should be noted that in this formula The function of is to express the dynamic force exerted by the mining equipment on each sampling point on the surrounding rock of the roadway during normal operation, which is the basis for calculating the dynamic load impact assessment value; It is the load safety reference value, used to quantify the degree of deviation from the actual load; is the attenuation coefficient of the roadway rock mass, obtained from the core vibration test, which represents the ability of the roadway rock mass to absorb vibration energy. The softer the rock layer, the larger the value. It is the vibration angular frequency of the mining equipment during operation, reflecting the vibration characteristics of the mining equipment during operation. The higher the frequency, the stronger the disturbance to the roadway rock mass. The design significance is to monitor whether the tunnel rock mass and the mining equipment will resonate during operation, which requires key monitoring. The acquisition method is to obtain the rock mass stiffness through acoustic wave detection. In this formula, The part reflects the average load state of the mining equipment during the operation cycle, and eliminates the interference of instantaneous overload or underload through time integration; in this formula Part of it is used to quantify the energy consumption effect of mining equipment vibration on the tunnel rock mass.
[0009] It should be noted that, as a preferred technical solution for the method for analyzing factors affecting roadway deformation based on data monitoring, the specific steps of S22 are: based on the external force data, support structure length data, and cross-sectional area data acting on the support structure at each sampling point of the roadway surrounding rock, the deformation evaluation value of the support structure at each sampling point of the roadway surrounding rock is calculated as follows: , where T is the operating cycle of mining equipment, is the external force acting on the support structure at the i-th collection point at time t during the operation cycle of the mining equipment, is the length of the support structure corresponding to the i-th collection point, is the cross-sectional area of the support structure corresponding to the i-th collection point, is the elastic modulus of the supporting structure, is the reference average deformation corresponding to the i-th collection point. It should be noted that in this formula The setting is because the deformation of the supporting structure is an external force, and the magnitude of the external force will be different at different time points; The setting is because the length of the support structure is proportional to the deformation it bears, and a long support structure is more susceptible to external forces than a short support structure; The reason for setting is that the cross-sectional area of the support structure determines its ability to resist external forces. The larger the area, the greater the pressure it can withstand. It is an important parameter to measure the stiffness of the support structure material. Materials with high elastic modulus deform less when subjected to external forces, while materials with low elastic modulus deform more when subjected to external forces. It is an important parameter for quantifying the degree of deviation of the support structure deformation; T reflects the cumulative effect of the support structure deformation under load. Considering the time effect can more accurately describe the state of the support structure during the operation cycle of the mining equipment. In this formula, The cumulative deformation of the support structure during the entire mining equipment operation cycle is analyzed in part by integrating the changes in the external forces acting on the support structure at each sampling point during the mining equipment operation cycle.
[0010] It should be noted that, as a preferred technical solution for the method for analyzing factors affecting roadway deformation based on data monitoring, the specific step of S3 is: based on the average bulk density data of the roadway surrounding rock, the mining depth data, and the goaf width data, the adjacent roadway impact assessment is performed.

It should be noted that in this formula represents the original ground stress, The method of obtaining is to obtain from the geological report, which is the basis for determining the original ground stress. H is obtained from the difference between the surface elevation and the roadway elevation. The larger H is, the higher the original ground stress is. D is obtained from the width of the goaf in the mining technical drawings. The wider the goaf is, the larger the stress transfer range is. k is obtained through rock strength testing. The harder the rock layer, the smaller k is. Characterizes the coupling effect of the span and depth of the goaf. When D is much smaller than H, it means that the goaf is narrow and the stress increase is weak. When D is much larger than H, it means large-scale mining and the stress increase is significant. The result of this formula is to analyze the stress increment of the overburden load of the tunnel transferred to the side of the tunnel after the formation of the goaf, and evaluate the impact of additional loads on adjacent tunnels when mining equipment is mining.
[0011] It should be noted that, as the preferred technical solution for the analysis method of factors affecting tunnel deformation based on data monitoring, the specific steps of S4 are: obtaining the tunnel surrounding rock stability assessment results and the adjacent tunnel influence assessment results, weighting the tunnel surrounding rock stability assessment value and the adjacent tunnel influence assessment value and adding them together to obtain the tunnel hazard assessment value; comparing the tunnel hazard assessment value with the set tunnel hazard assessment value threshold; if the tunnel hazard assessment value is greater than or equal to the set tunnel hazard assessment value threshold, the tunnel state is judged to be unqualified and an early warning is issued; if the tunnel hazard assessment value is less than the set tunnel hazard assessment value threshold, the tunnel state is judged to be qualified. It should be noted that there may be mutual correlation and influence between various risk factors during tunnel deformation. Weighted summation can comprehensively evaluate different risk factors, comprehensively consider various risks of tunnel deformation, and avoid focusing on a single factor while ignoring other important risk sources that cause tunnel deformation.

The result of this formula is to analyze the stress increment of the overburden load of the roadway after the formation of the goaf and to evaluate the impact of the additional load on the adjacent roadway when the mining equipment is mining. For example, The basis and benefits of the formula Indicates the original ground stress, which is the stress state naturally existing in the stratum and is the basis for evaluation. is the average bulk density of the rock formation surrounding the roadway, reflecting the weight of the rock formation per unit volume, which is crucial for calculating the distribution of ground stress. H represents the depth of mining activities, which directly affects the distribution of ground stress. D represents the span of the goaf, but for the sake of consistency, it can be understood as the key width parameter in the evaluation.

If the tunnel hazard assessment value is greater than or equal to the set tunnel hazard assessment value threshold, the tunnel state is determined to be unqualified and an early warning prompt is issued; if the tunnel hazard assessment value is less than the set tunnel hazard assessment value threshold, the tunnel state is determined to be qualified. It should be noted that there may be mutual correlation and influence between the various risk factors during tunnel deformation. The weighted summation can comprehensively evaluate different risk factors and comprehensively consider the various risks of tunnel deformation, avoiding focusing on a single factor and ignoring other important risk sources that cause tunnel deformation.
[0028] It should be noted here that the setting parameters (such as weights and thresholds, etc.) in this embodiment need to be set by technical personnel in this field based on relevant experiments.
