In the related technology, during the stoping of a working face, the stoping roadway is subjected to advanced mining to influence the mine pressure to develop violently, disasters such as roof fall, large deformation, rock burst and the like are easy to generate, and the existing control method is to carry out reinforced support design on the advanced section of the stoping roadway. Currently, the advance support range is determined based on engineering analogy, and the step pitch is determined by combining the period of the stoping period of the working face. The advanced support range obtained by the method has the advantages of single design process, lack of theoretical checking and verification, and easiness in occurrence of the condition of excessive or insufficient advanced support range.
In view of this, the present disclosure mainly solves the technical problem that the current advanced support range design method is single, and is difficult to perform quantitative analysis, and thus safety accidents easily occur in the mine, and fig. 1 is a flowchart of a method for determining an advanced support range according to an exemplary embodiment, and the method is applied to a terminal, as shown in fig. 1, and includes the following steps.
And step S11, responding to the received engineering geological parameters and the advanced support parameters, and constructing an engineering geological model according to the engineering geological parameters.
For example, in the mineral exploitation process, in order to prevent engineering safety accidents caused by collapse in a mine cavity, after the mine cavity is excavated to a certain extent in the mineral exploitation process, the mine cavity needs to be supported and fixed so as to prevent the collapse of the engineering mine cavity caused by lack of supporting components in the engineering surface of the mine cavity. Wherein, the support parts needed in the support fixing process can comprise support anchor rods, support anchor cables, support steel wire nets, explosion-proof nets, support timber and the like. The method comprises the steps of identifying and monitoring advanced support components in an engineering project through monitoring equipment, and determining advanced support parameters corresponding to all the advanced support components in the engineering project, wherein the advanced support parameters comprise support positions of the support components, types of the corresponding support components, size parameters of the support components and the like. In this embodiment, the advanced support parameters are the advanced support parameters corresponding to the support components already built in the engineering project, and the advanced support parameter information of the support components is collected through the monitoring equipment set in the engineering project in the field.

And identifying engineering geological parameters through a preset model, constructing an engineering geological model matched with the current engineering project, and analyzing advanced support parameters of the current engineering project based on the engineering geological model.
And S12, carrying out working face ore pressure rule analysis on the engineering geological model to generate engineering ore pressure data.
In this embodiment, stress analysis is performed on working face ore pressures of working faces in a current engineering project based on an engineering geological model, and engineering ore pressure data of the ore pressures changing along with the engineering progress is determined, where the current engineering progress may be marked based on the depth of an ore in the engineering project.
Optionally, in some embodiments, step S12 above includes:
performing three-dimensional numerical simulation analysis and three-dimensional model test analysis on the engineering geological model to generate an initial engineering ore pressure of the engineering geological model;
acquiring on-site mine pressure parameters corresponding to the engineering geological model acquired by preset monitoring equipment;
and verifying the initial engineering ore pressure based on the on-site ore pressure parameters to generate engineering ore pressure data.
In this embodiment, three-dimensional numerical simulation analysis and three-dimensional model test analysis are performed on the engineering geological model, so as to determine an initial engineering ore pressure of the engineering geological model, then a preset monitoring device which is set in the engineering project in the field is acquired, a field ore pressure parameter in the engineering project is acquired, the field ore pressure parameter is compared with the initial engineering ore pressure parameter, and if the field ore pressure parameter is matched with the initial engineering ore pressure parameter, the initial engineering ore pressure is used as engineering ore pressure data.
Optionally, in some embodiments, the step of verifying the initial engineering mine pressure based on the in-situ mine pressure parameter to generate engineering mine pressure data includes:
if the on-site ore pressure parameter is matched with the initial engineering ore pressure, taking the initial engineering ore pressure as engineering ore pressure data;
if the on-site ore pressure parameter is not matched with the initial engineering ore pressure, carrying out iterative modification on the preset verification analysis parameter based on the on-site ore pressure parameter so as to generate a target verification parameter;
performing three-dimensional numerical simulation analysis and three-dimensional model test analysis on the engineering geological model based on the target verification parameters to generate target engineering ore pressure;
and if the on-site ore pressure parameter is matched with the target engineering ore pressure, taking the target engineering ore pressure as engineering ore pressure data.
For example, in this embodiment, if the on-site mine pressure parameter is not matched with the initial engineering mine pressure parameter, training model parameters of three-dimensional numerical simulation analysis and three-dimensional model test analysis based on the on-site mine pressure parameter to obtain a trained three-dimensional numerical simulation analysis model and three-dimensional model test analysis model, and performing mine pressure analysis on the engineering geological model based on the three-dimensional numerical simulation analysis model and the three-dimensional model test analysis model to generate the initial engineering mine pressure parameter. In the embodiment, the initial engineering ore pressure can be verified based on the on-site ore pressure parameters, and when the error between the parameters is smaller, the initial engineering ore pressure is output as engineering ore pressure data; and if the errors among the parameters are larger, training a three-dimensional numerical simulation analysis model and a three-dimensional model test analysis model based on the on-site mine pressure parameters until the model reaches a convergence condition, and analyzing the engineering geological model based on the three-dimensional numerical simulation analysis model and the three-dimensional model test analysis model to generate engineering mine pressure data.
And S13, determining transformation trend data of the preset support component along with the position of the working surface according to engineering mine pressure data and advanced support parameters.
For example, in this embodiment, according to engineering mine pressure data and advanced support parameters, change trend data of each preset support component along with the position of the working surface in the advanced support parameters is determined, and the change trend data is analyzed, so as to evaluate rationality of the corresponding advanced support parameters.
Optionally, in some embodiments, step S13 above includes:
acquiring a safety monitoring threshold value and a monitoring parameter weight of a preset supporting component;
determining safety coefficient data of a preset supporting part according to the transformation trend data and the safety monitoring threshold value;
and determining the change trend of the safety coefficient according to the safety coefficient data and the monitoring parameter weight.
For example, in this embodiment, the preset supporting components include a plurality of preset supporting components, and based on the monitored parameter weights and the safety coefficient data of each preset supporting component, the safety coefficient data of each supporting component is weighted and averaged, so as to obtain the variation trend of the safety coefficient. By way of example, the monitoring parameter weight is determined by the influence degree of each parameter on the stability of the roadway, and the anchor rod safety coefficient weight w 1 Taking 0.2 of the weight w of the anchor cable safety coefficient 2 Taking 0.3, surrounding rock deformation safety coefficient w 3 Taking 0.4 and taking 0.1 as a stress safety coefficient of the bracket. The safety factor is determined based on the following calculation formula:
wherein C is i Safety factor for the ith monitored parameter, w i And the safety coefficient weight of the ith monitoring parameter.
And S14, determining the change trend of the safety coefficient of the preset supporting part according to the change trend data.
For example, in this embodiment, the change trend of the safety coefficient of the preset supporting component may be determined according to the stress condition of the preset supporting component and the monitoring threshold of the preset supporting component. For example, the preset supporting component is an anchor rod, stress change data of the anchor rod is determined through change trend data, the maximum stress threshold value of the anchor rod is obtained, the ratio of the stress change data to the maximum stress threshold value is used as the safety coefficient of the anchor rod, and therefore the safety coefficient change trend of the anchor rod along with the change of the position of the working surface is obtained.
Optionally, in some embodiments, step S14 includes:
according to the advanced support parameters, determining the support position and the support type of a preset support part in the engineering geological model;
according to engineering mine pressure data, supporting positions and supporting types, determining stress change data of a preset supporting component;
and generating transformation trend data according to the stress change data.
In this embodiment, the support position and support type of the preset support component in the engineering geological model are determined based on the advanced support parameter, and then stress change analysis is performed on the preset support component according to the engineering geological model, so as to generate change trend data of the preset support component in the engineering geological model.
And S15, generating an advanced support range according to the change trend of the safety coefficient.
For example, according to the change trend of the safety coefficient, a first engineering position in the engineering geological model, where the safety coefficient of the current preset supporting component is reduced, so that the safety in the mine channel begins to be reduced, and a corresponding second engineering position when the safety coefficient is reduced below a preset safety threshold are determined. The second engineering position corresponding to the preset safety threshold is an engineering position in the engineering geological model, where engineering accidents are about to occur, based on the currently preset supporting parts. And taking the range of the first engineering position and the second engineering position as the advance support range needing advance support.
Optionally, in some embodiments, step S15 includes:
acquiring a first transformation position and a second transformation position from the safety coefficient change trend, wherein the first transformation position is a corresponding engineering geological position when the safety coefficient starts to be reduced, and the second transformation position is a corresponding engineering geological position when the safety coefficient is smaller than a set safety coefficient threshold value;
and determining the range from the first transformation position to the second transformation position as a advance support range.
For example, in this embodiment, the safety factor is set to S, and whether advance support is needed at the corresponding engineering geological location is determined according to the S value. And setting the safety coefficient threshold corresponding to the S value to be 0.5. And determining a first transformation position corresponding to the beginning of the reduction of the S value in the engineering to model and a second transformation position corresponding to the S value smaller than 0.5 according to the variation trend of the S value, and taking the range between the first transformation position and the second transformation position in the engineering geological model as the advance support range. For example, if the S value of the monitoring section of the position of the advance working 100m is greater than 0.5 and the S value of the position of the advance working 110m is less than 0.5, the advance support is basically required in the range of the advance working surface 100 m-110 m.
According to the technical scheme, the engineering geological model is constructed according to the received engineering geological parameters and the advanced support parameters, working face ore pressure rule analysis is conducted on the engineering geological model to generate engineering ore pressure data, transformation trend data of the preset support component along with the position of the working face is determined according to the engineering ore pressure data and the advanced support parameters, safety coefficient change trend of the preset support component is determined according to the transformation trend data, and an advanced support range is generated according to the safety coefficient change trend. Therefore, the advanced support range in the mine channel is determined through data simulation and multiple data analysis, the accuracy of the advanced support range is improved, and the safety in the mine channel is ensured.
Fig. 2 is a schematic diagram of a method for determining a scope of advance support according to an exemplary embodiment, and as shown in fig. 2, the method is applied to a terminal, and includes the following steps.
The method comprises engineering geological model construction, multi-means comprehensive research, multi-parameter monitoring evaluation and advanced support range quantitative design. The engineering geological model comprises working face arrangement, geological conditions, supporting parameters and stoping speed, and basic data are provided for multi-parameter comprehensive analysis. The multi-means comprehensive research comprises mining pressure monitoring analysis, three-dimensional numerical simulation analysis and three-dimensional model test analysis, and mutual verification and supplement functions are achieved among the means.
For example, in some embodiments, three-dimensional numerical simulation and three-dimensional model trial analysis are two common means of studying the mining pressure law of a working surface, and mining pressure data, such as mining pressures and displacements at various positions of the working surface, which are difficult to monitor on site, are obtained. For numerical simulation analysis, engineering data and geological data are input into numerical simulation software to establish a numerical calculation model, and then calculation is performed to obtain desired data. For three-dimensional model test analysis, firstly, similar material proportioning is carried out according to on-site engineering geology, on-site engineering is scaled into a test frame, on-site construction process is reduced, ore pressure data is obtained, on-site monitoring and numerical simulation are supplemented and verified.
The multi-parameter monitoring analysis comprises anchor rod stress analysis, anchor rope stress analysis, surrounding rock deformation analysis and support stress analysis, and provides multi-scale reference for advanced support range determination. These parameters are all obtained by installing monitoring equipment on site, for example, the anchor rod/cable stress may be through an anchor rod cable dynamometer, the surrounding rock deformation may be through a convergent ruler, the support stress may be through a hydraulic support pressure gauge, etc. After the data are obtained, the data can be made into curves, and the rationality of the support parameters is evaluated by analyzing the change trend of the data along with the position relation of the working surface.
The quantitative design of the advanced support range comprises the steps of quantitative evaluation index proposal and multi-level analysis model establishment, and the advanced support range is determined through quantitative analysis of multi-parameter monitoring data.
For example, in some embodiments, the monitoring profile of the mine pressure monitoring analysis should be deployed during tunneling, with monitoring equipment having a real-time acquisition transmission function.
For example, in some embodiments, the three-dimensional numerical simulation analysis uses discrete element software for modeling, after the model is built, the calculation is firstly performed by taking the mine pressure monitoring data as a reference, and when the deviation value of the trial calculation result and the mine pressure monitoring result is smaller than the allowable value a, the numerical calculation model is considered to meet the calculation requirement.
For example, the three-dimensional numerical model in this embodiment calculates the same parameters as those obtained by on-site monitoring, such as anchor cable stress, support stress, surrounding rock deformation, surrounding rock pressure, etc., except that the parameters obtained by the numerical model calculation are richer and more comprehensive than those obtained by on-site monitoring, because on-site monitoring is affected by many factors such as stability of monitoring instruments, construction interference, cost, etc. In addition, the term "three-dimensional numerical model" refers to a model that is built by taking mine pressure monitoring data as a reference, and in order to ensure that the built model can fully reflect the site, the results obtained by modeling and the data monitored on site need to be compared, so that the reliability of the three-dimensional numerical modeling results can be ensured, and the address parameters (ground stress, rock mechanical parameters and the like) and engineering parameters (working surface size, roadway position and the like) of the site input by the three-dimensional numerical model
For example, in some embodiments, the established numerical calculation model is adopted to perform numerical operations under conditions of different mining progress, different coal seam thicknesses and the like, and the working face extraction advance influence range is primarily determined by analyzing surrounding rock stress, supporting stress and the like.
For example, in some embodiments, the three-dimensional model test analysis employs a large three-dimensional geomechanical model test system. And the similar material proportion, model body arrangement and test process design are based on engineering geological models, and the obtained results and the numerical simulation and mining pressure monitoring results are mutually verified and analyzed.
For example, in some embodiments, the monitoring parameters in the multi-parameter monitoring analysis are respectively that the anchor rod and the anchor cable take 80% of the yield strength, the surrounding rock deformation threshold takes 90% of the roadway cross-section, and the bracket threshold takes 70% of the bracket bearing capacity.
Illustratively, in some embodiments, the quantitative evaluation index includes a bolt safety factor c1, which represents a ratio of bolt force to a bolt monitoring threshold; the anchor cable safety coefficient c2 represents the ratio of the stress of the anchor cable to the anchor cable monitoring threshold value; the surrounding rock deformation safety coefficient c3 represents the ratio of the area after surrounding rock deformation to the surrounding rock deformation threshold value; and the bracket safety coefficient c4 represents the ratio of the bracket stress to the bracket stress threshold.
For example, in some embodiments, the S value in the multi-level analysis model is calculated by:
wherein C is i Safety factor for the ith monitored parameter, w i And the safety coefficient weight of the ith monitoring parameter.
For example, in some embodiments, the monitoring parameter weight is determined by the influence degree of each parameter on the stability of the roadway, the anchor rod safety coefficient weight w1 is 0.2, the anchor cable safety coefficient weight w2 is 0.3, the surrounding rock deformation safety coefficient w3 is 0.4, and the support stress safety coefficient is 0.1.
For example, in some embodiments, the value of the current monitoring position s is obtained through a multi-level analysis model, when the value of s is greater than 0.5, the range is considered to be seriously affected by the advance of the working surface, and the position enters an advance affected area to be an advance support range. For example, the S value is a basis for evaluating whether advance support is required at a certain monitored location. For example, if the S value of the monitoring section of the position of the advance working 100m is more than 0.5 and the S value of the position of the advance working 110m is less than 0.5, the advance support is basically required in the range of the advance working surface 100 m-110 m.
By the means of comprehensive field monitoring, numerical simulation and model test, a multi-parameter evaluation index and a comprehensive analysis model are established, a novel method is provided for reasonable determination of the advanced support, and accuracy of determination of the advanced support range is improved.
