When mining a mine, underground mine and rock are removed due to mining activities, and a goaf is gradually formed in a cavity area below the ground surface as time passes, and the goaf is a cavity area left after mining. The existence of the goaf has potential threat to the safe production of the mine and the surrounding environment. Because the top of the goaf and surrounding rock layers lose support, geological disasters such as earth surface collapse, rock movement and the like can be caused, and in addition, the goaf can also cause safety problems, thereby threatening the safety of miners and equipment.
Therefore, the goaf of the mine needs to be monitored and managed, and corresponding measures are taken to ensure the safe production of the mine and the environmental safety of surrounding areas. In the mining process, the settlement monitoring of the goaf is an important link for ensuring the safety of the mining process. If the subsidence of the goaf is not monitored, geological disasters and earth surface subsidence can be caused, so that the subsidence of the goaf is monitored very necessarily in order to ensure the safety of the mining process. The accuracy and the real-time performance of the settlement monitoring data are important to the management and the safety guarantee of the goaf; in order to know the settlement situation of the goaf in real time so as to take necessary measures in time, the settlement of the goaf needs to be monitored periodically, but when the settlement of the goaf is monitored at present, the acquisition frequency of monitoring data can only be acquired according to a preset time interval, but the accuracy and instantaneity of the monitoring can be influenced by the single data acquisition frequency, and when the data acquisition frequency is too high, the data redundancy can be caused, so that the data processing cost is increased; when the acquisition frequency is too low, key sedimentation velocity change information may be missed, so that the accuracy of monitoring is affected, namely, how to dynamically set the acquisition frequency according to the actual condition of mining, and the accuracy of monitoring data is improved.
Therefore, how to dynamically set the acquisition frequency according to the actual situation of mining, and improving the accuracy of the monitoring data is a problem to be solved urgently at present. The goaf settlement monitoring method provided by the embodiment of the application is applied to a server. The server of the present application may be a platform for providing goaf settlement monitoring service for mining, and fig. 1 is a schematic flow chart of a goaf settlement monitoring method provided in an embodiment of the present application, and referring to fig. 1, the method includes the following steps S101 to S104.

Before the first sedimentation velocity data is acquired, the position of the goaf monitored at this time in the mine is determined, and an example of any goaf is described.
According to characteristics and monitoring requirements of the goaf, mounting points capable of mounting settlement monitoring equipment in the goaf are obtained, and when the mounting points are selected, the goaf can be mounted at different positions and different heights, so that representativeness and accuracy of monitoring data are guaranteed. After the positions of the mounting points are selected, proper fixing brackets, such as cement piers, steel frames and the like, are selected according to the topography and the conditions corresponding to the positions of the mounting points, and the brackets are mounted on the ground at the selected positions. The settlement monitoring equipment in this application includes any one of layering settlement monitoring equipment, infrasound monitoring equipment, pressure sensor equipment, radar measurement equipment and earth's surface settlement monitoring equipment, when subsides monitoring equipment to goaf installation, can select suitable settlement monitoring equipment to install based on goaf's actual conditions.
The layered settlement monitoring equipment is suitable for carrying out settlement monitoring on an underground layered geological structure, and is especially suitable for monitoring layered settlement in projects such as mines, tunnels, foundation pits and the like. The settlement amount and the settlement rate of the underground layered geological structure can be measured by using the monitoring data of the layered settlement monitoring equipment, and real-time monitoring data and early warning signals are provided, so that engineering geological problems can be found and prevented in time.
The infrasound monitoring device is suitable for monitoring the stress and displacement change of underground rock and soil, and is particularly suitable for monitoring the stability of large-scale infrastructures such as mines, bridges, dams and the like. The monitoring data of the infrasound monitoring equipment can capture and analyze infrasound signals, calculate the stress and displacement change conditions of underground rock and soil, provide real-time monitoring data and early warning signals, and be helpful for timely finding and preventing engineering geological disasters.
The pressure sensor device is suitable for monitoring geomechanical parameters such as underground water pressure, soil pressure and the like, and is particularly suitable for monitoring construction safety of projects such as tunnels, foundation pits, dams and the like. The monitoring data of the pressure sensor equipment can measure parameters such as underground water pressure, soil pressure and the like, provide real-time monitoring data and early warning signals, and are favorable for timely finding and preventing engineering geological disasters.
The radar measurement device is suitable for measuring the topography of the earth surface, in particular for the topography measurement and settlement monitoring of mines and urban areas. The monitoring data of the radar measurement device can be used for carrying out high-precision measurement on the earth surface through a radar technology, so as to obtain the topographic and geomorphic data, provide real-time monitoring data and early warning signals, and be helpful for timely finding and preventing earth surface geological disasters.
The earth surface subsidence monitoring equipment is a CNSS earth surface subsidence monitoring system, and the earth surface subsidence speed is precisely measured by using a Global Positioning System (GPS) technology. The monitoring data of the earth surface subsidence monitoring equipment can be used for carrying out high-precision measurement on the earth surface elevation through various sensors and measurement technologies, acquiring earth surface subsidence data, providing real-time monitoring data and early warning signals, and being beneficial to timely finding and preventing earth surface subsidence problems.
In addition, after proper settlement monitoring equipment is selected according to the actual condition of the goaf, the settlement monitoring equipment is installed on the fixed support according to a specified operation flow, and the installation position and the height of the settlement monitoring equipment are ensured to meet the monitoring requirements. And then the sedimentation detection equipment is connected with the data acquisition device so as to transmit the acquired data in real time. And debugging and calibrating the installed sedimentation detection equipment, so that the sedimentation detection equipment can work normally and accurately collect data. The installed sedimentation detection equipment is required to be checked and maintained regularly in the follow-up process so as to ensure normal work and accurately collect data. After the subsidence monitoring equipment of the goaf is determined to be installed, the mining frequency corresponding to the current goaf is obtained, the mining frequency refers to the frequency of mining activities performed on the mine by a user, at this time, the user refers to the frequency of mining activities performed on the mine by a miner, namely, the mining activities can lead to the formation and the subsidence of the goaf, and the speed and the degree of the subsidence are closely related to the frequency of the mining activities. Therefore, in order to timely grasp the settlement condition of the goaf, the data acquisition frequency can be set based on the frequency of the mining activity when the goaf is initially set.
For example, when mining activities are more frequent, the initial collection frequency may be set denser, i.e., the time intervals of the collection frequencies are shorter, so as to grasp the settlement of the goaf in time. When the mining activity is sparse, the initial acquisition frequency can be set to be sparse, namely the time intervals of the acquisition frequency are long, so that the settlement monitoring equipment can continuously monitor the goaf to ensure the safe production of the mine.
In addition, the frequency of the mining activities can be represented by numerical values, when the goaf is subjected to one mining activity for 1 day, and the duration of each mining activity is not less than 10 hours, namely the frequency of the current mining activity is confirmed to be defined as frequent collection; when a mining activity is performed on the goaf for 3 days, and the duration of each mining activity is not more than 3 hours, namely, the frequency of defining the current mining activity as sparse acquisition is confirmed, and particularly how to define the frequency of the mining activity can be set based on actual conditions, and the method is not limited.
Further, after the acquisition frequency corresponding to the goaf is determined, the sedimentation speed data of the sedimentation monitoring equipment on the goaf is acquired, and as a plurality of sedimentation monitoring equipment are installed in one goaf, each sedimentation monitoring equipment acquires the sedimentation speed data corresponding to the current position, and a plurality of sedimentation speed data are obtained. After a plurality of sedimentation velocity data are acquired, the acquired sedimentation velocity data are screened, abnormal values and error data are removed, and the accuracy and reliability of the data are ensured. And converting the sedimentation velocity data into a unified standard format for subsequent processing and analysis, and cleaning the data to remove redundant data and repeated data, thereby ensuring the quality and the precision of the data. And finally, carrying out statistics and analysis on the processed sedimentation velocity data to obtain accurate sedimentation velocity data, wherein the first sedimentation velocity data is any one sedimentation velocity data in a plurality of sedimentation velocity data.
S102: a first acquisition frequency of the goaf is acquired.
In S102, after acquiring the first sedimentation velocity data, the server acquires the acquisition frequency of the sedimentation monitoring device for the goaf, that is, the initial acquisition frequency of the current sedimentation monitoring device for the goaf, that is, the first acquisition frequency.
For example, when the settlement monitoring device is a pressure sensor device, the initial acquisition frequency is set to be once every 3 hours, i.e., the first acquisition frequency is once every 3 hours, according to the mining activity frequency of the goaf. If the first acquisition frequency of the goaf is the adjusted acquisition frequency, the adjusted acquisition frequency is acquired, namely the acquisition frequency currently used by the sedimentation monitoring equipment.
S103: and calculating the first sedimentation velocity data to obtain the sedimentation velocity change rate.
In S103, after obtaining the first sedimentation velocity data, the server needs to calculate the first sedimentation velocity data to obtain the current sedimentation velocity change rate, and the specific calculation process specifically includes: firstly, data from a ground preset point to the vertical height of the bottom of the goaf, namely target ground surface height data, is required to be acquired, wherein the ground preset point refers to a corresponding ground position in a mine, namely a ground position corresponding to the top of the goaf. Since the goaf is a hollow region under the ground surface, the goaf is composed of the top and bottom of the ground surface, the top is the position closest to the ground surface, and the bottom is the position farthest from the ground surface. The ground level is generally the vertical distance from a point on the ground surface to the bottom of the goaf. The original height of the ground surface may be changed due to the existence of the goaf, and the ground surface height of a certain point on the ground surface can be determined by measuring the vertical distance from the point to the bottom of the goaf. In measuring the target surface height data, the shape and change conditions of the goaf, such as the shape, size, inclination angle and the like of the goaf, and the topography and geological conditions of the surface, need to be considered. Therefore, proper measuring methods and equipment are needed to be selected for measurement, the equipment comprises a level gauge, a theodolite, a total station and the like, the equipment can acquire the ground surface subsidence data by measuring the elevation change of the ground surface, and the ground surface subsidence data is the first subsidence speed data. And acquiring a time point corresponding to the first sedimentation velocity data, namely a target time point, wherein the time point corresponding to the first sedimentation velocity data can be further understood as a time separated from a historical time point, and the historical time point represents the time point of acquiring the sedimentation velocity data last time. The sedimentation velocity is obtained according to the ratio between the target surface height data and the target time point, namely the sedimentation velocity is obtained by dividing the target surface height data by the target time point, and the sedimentation velocity is a velocity condition for helping to analyze the surface sedimentation, and is very important for correspondingly detecting the sedimentation change of the underground goaf. Sedimentation velocity refers to the degree of change in surface height per unit time, i.e., sedimentation velocity. After obtaining the sedimentation velocity, obtaining the sedimentation velocity change rate, wherein the sedimentation velocity change rate refers to the ratio of the sedimentation velocity to the target time point, namely dividing the sedimentation velocity by the target time point, so as to obtain the sedimentation change rate. The sedimentation rate change rate can determine the sedimentation change trend of the goaf so as to facilitate the subsequent adjustment of the collection frequency of the goaf according to the sedimentation change trend.
For example, at an initial time, the target surface height data is 50 meters, the target time point is 5 hours, the current surface height data is 40 meters, the sedimentation velocity is obtained by dividing the target surface height data by the target time point, that is, 50 is divided by 5 to be equal to 10 meters per hour, and the sedimentation rate is obtained by dividing the sedimentation velocity by the target time point, that is, 10 is divided by 5 to be equal to 2 meters per hour, so the sedimentation rate is 2 meters per hour.
In addition, the sedimentation velocity change rate can be compared with historical ground surface height data according to target ground surface height data, and the historical ground surface height data is obtained according to a target time point, wherein the target ground surface height data is the monitoring data acquired by the server at this time, and the historical ground surface height data is the monitoring data before the current ground surface height data is acquired. And obtaining the difference between the historical ground surface height data and the target ground surface height data, and dividing the difference by the target time point to obtain the sedimentation velocity change rate. The rate of change of sedimentation velocity may also be achieved by other means, which are not illustrated here.
S104: and adjusting the first acquisition frequency according to the sedimentation velocity change rate so as to facilitate the sedimentation monitoring equipment to acquire data of the sedimentation of the goaf.
In S104, after the server obtains the rate of change of the sedimentation velocity of the goaf, the server dynamically adjusts the first collection frequency according to the rate of change of the sedimentation velocity, and may adjust the first collection frequency according to a comparison result of the rate of change of the sedimentation velocity and a preset sedimentation velocity threshold value, and may also adjust the first collection frequency according to weather information and the sedimentation velocity currently corresponding to the goaf. The dynamic adjustment includes three modes, and the three adjustment modes are described in turn.
In the first adjustment mode, whether the sedimentation velocity change rate is larger than or equal to a preset sedimentation velocity threshold value is judged, the preset sedimentation velocity threshold value is set according to the geological stability of the goaf, when the geological stability is better, the set threshold value is higher, and when the geological stability is worse, the set threshold value is lower. Because the geological stability corresponding to different goafs is different, the preset sedimentation velocity threshold corresponding to different goafs is different, and the geological stability corresponding to the current goafs is required to be determined before the sedimentation velocity change rate of the goafs is acquired, so that the preset sedimentation velocity threshold is determined according to the geological stability.
When the sedimentation velocity change rate is greater than or equal to a preset sedimentation velocity threshold value, confirming to acquire a first time interval corresponding to the first acquisition frequency, adjusting the first time interval to a second time interval corresponding to the second acquisition frequency, wherein the second acquisition frequency is the acquisition frequency corresponding to the first acquisition frequency. When the sedimentation velocity change rate is large, the first time interval can be adjusted to the second time interval, namely the first acquisition frequency is improved, so that the sedimentation data of the goaf can be acquired more comprehensively and accurately. Through increasing first collection frequency, can catch the change condition of collecting space area sedimentation velocity in time, realize real-time supervision, can reduce the possibility that leaks to take, if the time interval that first collection frequency set up is longer, then there is the condition that leaks to take.
For example, the first time interval corresponding to the first collection frequency is 2 hours, that is, the sedimentation velocity data of the goaf is collected every 2 hours, when the sedimentation velocity change rate is greater than the preset sedimentation velocity threshold value, the first time interval needs to be adjusted to be a second time interval, and the second time interval is 1.5 hours, that is, the sedimentation velocity data of the goaf is collected every 1.5 hours, so as to better capture the change of the sedimentation velocity of the goaf.
The second adjusting mode is to judge whether the sedimentation velocity change rate is larger than or equal to a preset sedimentation velocity threshold value; when the sedimentation velocity change rate is smaller than a preset sedimentation velocity threshold value, confirming to acquire a first time interval, adjusting the first time interval to a third time interval, wherein the third time interval is a time interval corresponding to a third acquisition frequency, and the third acquisition frequency is an acquisition frequency corresponding to a reduced first acquisition frequency. When the sedimentation velocity change rate is smaller, the first time interval can be adjusted to be a third time interval, namely, the first acquisition frequency is reduced, redundant data is caused by the fact that the current first acquisition frequency is too high, unnecessary data acquisition can be reduced by reducing the first acquisition frequency, and the processing and storage cost of the data is reduced. Reducing the first acquisition frequency can also reduce the working time of the sedimentation monitoring equipment, thereby reducing the consumption of electric power and other resources and saving energy and resources. The first acquisition frequency is reduced to reduce the data volume, so that the efficiency of subsequent data processing is improved, less data needs to be transmitted, stored and analyzed, and the burden of data processing is reduced.
For example, the first time interval corresponding to the first collection frequency is 2 hours, that is, the sedimentation velocity data of the goaf is collected every 2 hours, when the sedimentation velocity change rate is smaller than the preset sedimentation velocity threshold value, the first time interval needs to be adjusted to be a third time interval, and the third time interval is 2.5 hours, that is, the sedimentation velocity data of the goaf is collected every 2.5 hours, so as to better capture the change of the sedimentation velocity of the goaf.
The third adjustment mode can also adjust the acquisition frequency of the goaf according to weather information corresponding to the goaf, so as to obtain weather information corresponding to the goaf, wherein the weather information is obtained by monitoring the goaf by weather equipment, and the weather equipment comprises any one of weather equipment in a weather station, satellite remote sensing, a radar and an automatic weather station. Judging whether the weather information is preset weather information or not, wherein the preset weather information comprises any one weather information of rainfall weather, strong wind weather and high temperature weather; under severe weather conditions, rainfall weather, strong wind weather and high temperature weather all can influence the sedimentation velocity of the goaf, so that the sedimentation velocity changes, and in order to timely acquire the sedimentation velocity corresponding to the goaf, the first acquisition frequency can be adjusted according to weather information and the sedimentation velocity of the goaf. When weather information is preset weather information, the first acquisition frequency is confirmed to be required to be adjusted. The sedimentation rate of the goaf is accelerated when the weather information is preset, so that the acquisition frequency can be increased to ensure the accuracy and the safety of data, and the sedimentation condition of the goaf can be better monitored.
In addition, the sedimentation speed of the goaf is lower when the weather information is not the preset weather information, and the first acquisition frequency can be properly reduced, so that unnecessary resource waste is reduced. After the first acquisition frequency of the goaf is adjusted by considering the weather information, pre-warning and countermeasure measures for the preset weather information are further enhanced, so that the safety production of the mine is ensured.
Still further, after the dynamic adjustment of the first acquisition frequency is determined according to the above manner, if the first acquisition frequency is adjusted to the third acquisition frequency, the goaf needs to be monitored again by the settlement monitoring device according to the third acquisition frequency so as to obtain second settlement speed data, and the second settlement speed data represents data for monitoring the goaf by using the adjusted third acquisition frequency after the adjustment of the first acquisition frequency. If the first acquisition frequency is adjusted to the second acquisition frequency, the goaf is monitored again by the sedimentation monitoring equipment according to the second acquisition frequency so as to acquire third sedimentation velocity data. In the application, the steps except installation are repeated to realize continuous monitoring of the goaf sedimentation velocity and dynamic adjustment of the data acquisition frequency. Aiming at the areas with small sedimentation velocity change, the acquisition frequency can be reduced, the acquisition of invalid data is reduced, and the data acquisition efficiency is improved. Aiming at the areas with larger sedimentation velocity change, the acquisition frequency can be increased, the data can be acquired more comprehensively, and the data acquisition precision is improved, so that the data requirement on goaf sedimentation monitoring can be better met.
