Description

一种基于激光测距的危岩变形多点信息提取及报警系统A multi-point information extraction and alarm system for dangerous rock deformation based on laser ranging

技术领域 technical field

本发明属于地质工程、矿山工程技术领域,尤其是涉及一种基于激光测距系统的危岩变形多点信息提取及报警装置。 The invention belongs to the technical fields of geological engineering and mine engineering, and in particular relates to a multi-point information extraction and alarm device for dangerous rock deformation based on a laser ranging system.

危岩体变形监测工作贯穿防治工程实施前、中、后各阶段,通过严密监测危岩体变形动态,可以预测危岩体的稳定性与变形发展趋势、反馈防治施工设计、指导施工并检验防治效果起了重要的作用。目前,常采用的变形监测手段包括三维激光扫描监测、全站仪定点变形监测、局部裂缝变形监测。三维激光扫描监测精度高,能够准确并详细了解整个危岩各点变形发展趋势,但由于激光扫描仪成本较高,不能够用于实时监测;全站仪能够准确的了解特定控制点的变形发展趋势,但同样由于成本较高,不能够用于实时监测;局部裂缝变形监测能够实时监测特定裂缝的变形发展趋势并预警,但其代表性较差,不能够反应整个危岩体的变形发展趋势。综上所述,目前尚无一款能够实时监测多点变形和预警的危岩变形监测装置。 The monitoring of the deformation of the dangerous rock mass runs through the stages before, during and after the implementation of the prevention and control project. By closely monitoring the deformation dynamics of the dangerous rock mass, it is possible to predict the stability and deformation development trend of the dangerous rock mass, feedback the prevention and control construction design, guide the construction and inspect the prevention and control Effects play an important role. At present, the commonly used deformation monitoring methods include three-dimensional laser scanning monitoring, total station fixed-point deformation monitoring, and local crack deformation monitoring. The three-dimensional laser scanning monitoring has high precision, and can accurately and detailedly understand the deformation development trend of each point of the entire dangerous rock. However, due to the high cost of the laser scanner, it cannot be used for real-time monitoring; the total station can accurately understand the deformation development of specific control points However, due to the high cost, it cannot be used for real-time monitoring; local fracture deformation monitoring can monitor the deformation development trend of specific cracks in real time and provide early warning, but its representativeness is poor, and it cannot reflect the deformation development trend of the entire dangerous rock mass. . In summary, there is currently no dangerous rock deformation monitoring device capable of real-time monitoring of multi-point deformation and early warning.
