3D Laser Scanning in Mining – Enhancing Safety and Efficiency
摘要
Mining is a high-risk industry due to the nature of the mining environment. In recent years, modern technologies such as 3D laser scanning (TLS) have been introduced to increase safety and efficiency in mining operations. This article will provide an overview of the applications of 3D laser scanning in mining, with a focus on enhancing safety in the mining environment. The potential of 3D laser scanning is considerable, allowing for accurate determination of the shape and dimensions of the mining space. This method is primarily used to create accurate mine maps, crosscuts and to monitor changes in the spatial structure during mining. By obtaining accurate and reliable data on the shape of road-ways, tunnels, and excavations, 3D scanning enables precise planning of mining work and monitoring of progress, which can help avoid dangerous situations such as caving or roof collapses. Despite the limitations of the technology such as the price and environmental factors, 3D scanning is an established and proven method used in underground research work in mines. Its application brings real benefits in terms of increasing worker safety and improving work efficiency in mines. In summary, 3D laser scanning is a valuable tool for enhancing safety and efficiency in mining operations, and its potential should not be overlooked by the mining industry. Monitoring of roadway deformations is one of the most important issues in mining practice. The application of 3D laser scanning technology is particularly well-suited for monitoring strata displacements, roadway deformations, and the deformation of steel arch supports. This technology enables the comprehensive capture of complex spatial data, encompassing the entire area around the monitored roadway, including all types of deformations occurring ahead of the longwall face. By conducting repeated scans over time, this method can detect and track movements ranging from a few millimeters to several centimeters. When combined with other measurement instruments, such as CCBM and CCBO probes or extensometers, 3D laser scanning provides results that reveal deformations in new and insightful contexts.
