During a mine exploitation, the activity of the mine shafts must be carried out under outstanding safety conditions, given that through them we carry out the transport of personnel and materials necessary for the production process and we extract mineral substances.
For these reasons, the operating parameters must be within the limits provided by specific regulations, both in the case of supporting and guiding elements of the shaft, as well as those of the extraction plant. The labor protection regulations provide the mandatory time period within which the technical verification of the extraction plant needs to be completed (at least once every six months), the parameters that need to be determined and compared with the permissible limits (the verticality of the shaft tower, horizontal and parallel axis of the spindles, position of the axes of the wheels in relation to the axis of the extraction plant, the deflection angle of the cables). Observations are made regarding the integrity of the construction elements (the shaft tower and the extraction machine house) and their spatial position, as well as to the static and mobile elements of the extraction machine. Because the extraction machine is located in the house of the extraction machine, and the spindles are located in the tower of the well, it is often difficult to make said observations. The classical method of verification requires developing a polygonal route through which observations can be made regarding the elements of the extraction plant and also regarding the elements of the extraction well tower, and also the processing of said observations. The following paper presents a method of data retrieval for the verification of the single-cable extraction installation of a shaft, by means of combined measurements of directions and distances with the use of conventional total stations, and the processing of the aforementioned observations. |
