Abstract: Industrial chimneys are used to create a natural draft and conduct smoke waste into the atmosphere and disperse it to acceptable concentrations. Currently, chimney emergencies are not uncommon. The main causes of accidents are investigated and established by energy experts. Geodetic monitoring is an integral part of the system of technical control of industrial facilities, the essence of which is the periodic determination of the values of rolls, deviations and deformation of load-bearing structures. According to the results of such monitoring, if necessary, a set of preventive measures is being developed to eliminate the roll in order to ensure trouble-free operation of the structure. The article proposes a method for measuring small horizontal angles between the left and right forming pipes using a total station Leica TS06 plus. As an example of the implementation of the proposed method, the results obtained during control measurements of the roll of the trunks of three chimneys on the territory of the GRES in Kuzbass are given. The proposed technique makes it possible to perform an effective assessment of the accuracy of determining rolls from a single observation point using an electronic total station. The production of observations on various visible belts of chimney trunks makes it possible to abandon the construction of special observation platforms, the laying and subsequent preservation of geodetic reference points, which reduces the cost of field work and increases the level of safety. The method is applicable for various heights and configurations of tower-type structures, and also allows you to quickly monitor rolls and obtain results in an automated mode analytically and graphically. The disadvantages of the method include the influence of the tool's standing point and concreting defects on the measurement results.
