Abstract
The article discusses the use of laser scanning technology for observing the deformations of pit walls in iron ore deposits. To carry out observations and analysis of the results obtained, an iron ore quarry in the Akmola region was selected. The task of the study is to summarize the methods and technical means used at mining enterprises for observing and measuring deformations in moun-tain ranges. The safety and efficiency of iron ore quarries is largely determined by the methods used to monitor the deformation process and calculate the stability of the pit walls and dumps. Based on the analysis of existing approaches to solving this problem, a conclusion was drawn on the advisabil-ity of using a laser scanning system for assessing sustainability. As a result of the analysis of the ob-tained measurement results, a digital model of the quarry near-surface arrays was obtained, which allows you to create an electronic database for further use in surveying and geomechanical tasks.
