ABSTRACT
In rock engineering such as mine engineering and tunnel engineering, the rock mass structure plays a key role in the strength, seepage and stability of the rock mass. Therefore, the geometric parameter statistics of structural planes in rock mass engineering is an important geological survey work. Traditional rock mass structural plane measurement methods are limited by various on-site conditions. With the application of advanced measurement technologies in underground mines, the measurement methods of rock mass structural planes have also been updated. Among them, photogrammetry and 3D laser scanning measurement are new methods suitable for measuring the structural planes of underground rock mass. Through the detailed comparison and analysis of three typical structural plane measurement methods, the 3D laser scanning technology has proven to have an incomparable advantage in the collection of rock mass structure measurement. It has explored a new way for the rapid collection of rock mass structure plane occurrence in areas with harsh geological conditions.
