The development of mineral deposits very often occurs in stages. First, open-cut mining, then underground one. At the same time, the arrangement of shafts is always problematic, when it is necessary to choose between security and economic efficiency. Design solutions always convince us that the main thing is safety, but is it really so? This article is the initial stage in the formulation of a very topical issue, in the opinion of the authors, which consists in developing a method for estimating and forecasting the change in the state of shafts during operation. Experimental work was carried out at "Gaiskoe" underground mine, where seven shafts are located in operation, located 100-200 meters from the collapse zone, the depth of the trunks is more than 1300 meters. The main purpose of the research was to determine the wandering from the vertical axis of the trunk at different depths.
Key words: Stress-strain state / Deformation / Rock shift / Control of linear parameters
