Description

Technical Field

[0001] The invention relates to the technical field of coal mine monitoring, and in particular to a coal mine slope monitoring system. Background Art

[0002] Open-pit mine slope monitoring plays an important role in ensuring the safe production of mines. At present, slope deformation monitoring often uses two methods: manual patrol and monitoring equipment. Commonly used monitoring equipment includes slope monitoring (rangefinder, total station, level, liquid level, theodolite, etc.) multi-point mobile instruments, inclinometers, GPS measurement, synthetic aperture radar interference monitoring, ground microseismic monitoring, distributed network structure fiber optic offset monitoring, and time domain reflection monitoring. Among them, three-dimensional laser scanning technology, that is, three-dimensional on-site scene replication technology, breaks the limitations of point-to-point monitoring in traditional technologies, and has the advantages of wide collection area, long distance, high image density, and high reliability. In recent years, it has gradually been widely used in the assessment, monitoring and instability prevention of the safety status of surface movements on steep slopes and large hazardous sources.

[0003] Compared with traditional monitoring methods, 3D laser scanners mainly use non-contact methods to complete the 3D coordinate extraction of physical objects, and the obtained point cloud format can be directly used in computer-related processing software, which greatly improves the monitoring effect and quality. The main advantages of 3D laser scanners are as follows:

[0004] First, non-contact. Most traditional monitoring methods require human participation. When monitoring certain complex terrains, it is difficult to ensure the accuracy of the monitoring results, which can also pose a threat to human life. The non-contact advantage of 3D laser scanners is that they can obtain actual 3D coordinates without human participation, greatly reducing the intensity of manual labor.

[0005] Second, the monitoring efficiency is high. The use efficiency of 3D laser scanners in open-pit coal mine monitoring is relatively high. Under normal circumstances, the rate of point information extraction can exceed one billion per second, and this technology is also more suitable for extracting 3D position information of some major physical objects, which shows its superiority in monitoring effect.

[0006] Third, information initiative. Different from previous monitoring technologies, 3D laser scanners can emit information autonomously, and no longer rely on external light sources for monitoring. Instead, they can collect coordinate information of physical objects by monitoring the echo of the emitted information.

[0007] Fourth, high penetration. Because the sampling distance of the 3D laser scanner is very small and the sampling density is very high, it can be used in areas with sparse vegetation to enable the laser signal to quickly reach the target object and obtain geometric data from all angles of the object.

[0008] Fifth, accuracy. The target signals obtained by the 3D laser scanner are characterized by high density and high precision. At the same time, the collection points are evenly distributed and the resolution is high, thus ensuring the accuracy, safety and reliability of the final measurement data.

[0009] Sixth, automation. As a major product in the digital age, this technology has perfect intelligent characteristics. Its data collection, storage and management can be realized autonomously, which greatly reduces the failure rate caused by manual work.

[0010] Seventh, integration. This technology can also be combined with other monitoring technologies, such as the integration of 3D laser scanners and GPS technology. On the premise of having their own advantages, it also integrates the positioning function of GPS technology, which helps to obtain accurate signals of physical objects more quickly and ultimately ensure the correctness of monitoring results.

[0011] However, the working environment of open-pit coal mines is complex, and the use of 3D laser scanners outdoors is easily affected by factors such as weather and working environment, which will have a certain impact on the equipment, such as damage, thereby affecting the monitoring of the equipment; in addition, although the 3D laser scanner itself has high precision, temperature changes may cause slight deformation of its internal mechanical structure or electronic components, which will have a certain impact on the accuracy of the scanning results and the stability of the equipment.

The box body 2 can be raised when in use. After use, the box body 2 can be lowered to cover the three-dimensional laser scanner 6 inside, so as to avoid it being exposed to the outdoor environment for a long time and provide it with certain protection. At the same time, due to the complex environment and high dust content of open-air coal mines, the influence of dust and other impurities on the three-dimensional laser scanner is reduced, such as dust adsorbed on the lens of the three-dimensional laser scanner. The temperature inside the box body 2 is controlled by setting a heating unit 32 and a cooling single ring to keep the three-dimensional laser scanner 6 in a stable temperature environment, thereby ensuring the accuracy of the scanning results and the stability of the equipment.
