Abstract:

Structural features of a rock massif are one of the most important factors determining the geomechanical processes. The method of their study was limited mainly to the direct measurements in outcrops at the surface, on the slopes of quarries and mines by a mining compass. Nowadays, mine surveying employs modern electronic devices such as 3D scanner and others. A laser scanner can be used to capture possible fracture if the device is arranged within 300 meters from the massif. One of the major advantages of the laser scanning is the possibility of obtaining information on the status of dip fractures and the size of structure blocks without direct contact of the worker with the massif. In addition, the laser scanner can be used in iron-ore opencast mines, unlike the mining compass.

Purpose. Development of the surveying method based on 3D laser scanning in opencast mines, which will reduce the measurement time and allow creation of three-dimensional models of ore bodies taking into consideration their structure.

Methodology. The research employed the surface laser scanning of rock fractures in opencast mines, collecting data in real time and computer analysis of the results.

Findings. Methods of terrestrial laser scanning for obtaining data on geometrical parameters of opencast mines, crack occurrence and faults have been developed.

Originality. The new method of surveying the structural features of a rock massif based on 3D laser scanning allows for instant three-dimensional visualization of the survey results with a high information content, precision and productivity.

Practical value. The new method is intended to create a 3D model of a dip fracture, fault and ore body reflecting its structure.
