Air-space-ground integrated measurement and control method for tailings reservoir risk

Abstract

The invention discloses an air-space-ground integrated measurement and control method for tailings reservoir risk in the technical field of mine safety risk monitoring, the steps including follows: 1.remote sensing satellite photos of different time periods in a mine area are obtained, and then normal libraries and suspected abnormal libraries are screened out, and difference point areas of the suspected abnormal libraries are found out; 2. according to starting threshold condition of unmanned aerial vehicle, the unmanned aerial vehicle is started to conduct low-altitude aerial survey of thesuspected abnormal libraries to obtain two-dimensional spatial data information; 3. according to starting threshold condition of three-dimensional laser, the three-dimensional laser is started to measure the suspected abnormal libraries to obtain three-dimensional spatial data information and establish a three-dimensional spatial model; 4. when the parameters index of the three-dimensional spatialdata information reaches the threshold range, real-time monitoring is started; 5. abnormal indicators are monitored in real time and early alert is issued. The air-space-ground integrated measurement and control method for the tailings reservoir risk realizes the multi-level monitoring of tailings reservoir in a wide range, and obtains the parameters data of the tailings reservoir in time, quantitatively and at low cost, and can alert the risk.

Description

technical field [0001] The invention relates to the technical field of mine safety risk monitoring, in particular to a tailings pond risk space-air-ground integrated measurement and control method. Background technique [0002] Tailings pool refers to the place where dams are built to intercept valley mouths or enclosures, and are used to stockpile metal or non-metal mines for ore sorting and then discharge tailings or other industrial waste. The tailings pond is a high potential energy man-made debris flow hazard, and there is a danger of dam failure. Once the accident occurs, it is easy to cause serious accidents. Regarding the environmental risk assessment and monitoring of tailings ponds, my country is in the stage of gradually advancing and becoming more mature. [0003] In the prior art, common monitoring methods for tailings ponds include: remote sensing satellites, three-dimensional lasers, and the like. Remote sensing satellite images have the advantages of large-...

AI Technical Summary

Problems solved by technology

Remote sensing satellite images have the advantages of wide range, time-space continuity, periodicity, easy acquisition and low cost, but only image data can be obtained, the resolution is limited, and detailed data for analysis is lacking; 3D lasers can collect landslides at risk. Detailed data is convenient for quantitative analysis, but when the monitoring range is wide, the cost is high and time-consuming, some places are not easy to reach the detection site, and it is difficult to fully grasp major system risks
