Example Embodiment

[0027] The present invention will be further described below in conjunction with the drawings.

[0028] Such as Figure 1-5 As shown, a mine slope monitoring method combining three-dimensional laser scanning and GPS of the present invention is characterized in that: the three-dimensional laser scanner system is organically combined with the GPS monitoring and positioning system to accurately monitor the slope geological disasters ,Specific steps are as follows:

[0029] (1) First, set up a monitoring pile I1 on the central axis of the monitored slope. The monitoring pile I1 includes a fixed base 1-1, a centering hollow rod 1-2 arranged in the upper middle of the fixed base 1-1, and set On the support plates 1-3 around the fixed base, the upper, middle and lower three positions of the centering hollow rod 1-2 are welded two by two to form a cross-shaped support bolt rod 1-4 perpendicular to each other. The supporting plate 1-3 is provided with bolt holes, the supporting plate 1-3 ...

Abstract

The invention relates to a three dimensional laser scanning-GPS-combined side slope monitoring method. The monitoring method is characterized in that a three dimensional laser scanner system and a GPS monitoring positioning system are combined and are used for accurate monitoring of side slope geologic hazard. The method can accurately detect and forecast mine side slope geologic hazard, improve side slope monitoring intelligence and prediction effects, realize real-time monitoring of side slope deformation, accurate prediction of side slope deformation trend and precaution of geologic hazards such as side slope displacement and falling and guarantee mine production safety.

Description

technical field [0001] The patent of the present invention relates to the technical field of geological disaster monitoring, in particular to a mine monitoring method combining three-dimensional laser scanning and GPS. Background technique [0002] Slope monitoring is an important measure to ensure the safe construction of roads, railways, open-pit mines, reservoir banks, etc., and the open-pit mine slope has been in the dynamic excavation process for a long time. How to carry out long-term, effective and accurate slope monitoring is a key issue for mines. A difficult problem that enterprises urgently need to solve. [0003] At present, there are many methods for slope displacement monitoring, such as geodetic observation, instrument observation, GPS observation, close-range photogrammetry and so on. According to the equipment installation collection method, it can be divided into two categories: contact measurement method and non-contact measurement method. [0004] The G...
