Abstract
The paper presents made for Salt Mine „Wieliczka”: . It was used during the monitoring of sealing the rock around the mine shaft "Kosciuszko", and now serves for periodic visual inspection. Due to the fact that ongoing work injection may lead to deformation of the shaft lining and reinforcement the system that allowed real-time monitoring of the shaft was built. The processing of data obtained from recorded movies and photos gives also possibilities to generate a numerical model of the shaft in the form of a three-dimensional point cloud. In order to determine the accuracy of the 3D model a comparative analysis of a cloud of points obtained from laser scanning was made. Multistage accuracy analysis showed a high correlation between the models in the analyzed portion of the shaft. The mean square error of the model was calculated which amounted ±33mm. The precision of the spatial model demonstrates the usefulness of the system for acquiring 3D data in vertical mine excavations. The acquired experience allows for continuous improvement of the system and increasing the accuracy of the data obtained by this method.
