Description

Technical Field

[0002] Mine surveying technology and methods play a vital role in the mining industry. They are used to accurately measure and record key data such as mine geological features, ore reserves, and mining progress, providing essential data for mine planning, design, and management. Surveying and mapping are essential for the orientation and measurement of major tunnels, the calibration of the centerline of excavation tunnels, and underground tunnel penetration, reserve calculations, and comparisons between above and below the shaft. Traditional surveying methods primarily use steel tape and rope distance measurement. While simple and direct, these methods are limited by the accuracy and length of the tools, making them difficult to apply to projects requiring high precision.

[0003] Currently, underground coal mine surveying operations can utilize a total station coupled with a gimbaled prism for distance measurement. This method offers advantages such as long range, short measurement times, and high accuracy. However, because the underground observation point is located at the top of the tunnel, a tripod is required to position a prism below the observation point's plumb line for distance measurement. This is not only time-consuming for surveyors, but also requires carrying numerous tools and is labor-intensive. Setting up the prism can also be difficult and dangerous when the survey station is located above a roadheader or conveyor belt. Utility Model Content
