PARAMETERS REFINING AND MONITORING FOR VERTICAL DEFORMATIONS OF THE AXLE OF MINE SHAFT ON THE WORKED SPACE

Abstract

The development of mineral deposits very often occurs in
stages. First, the field is mined as open, then they switch to
the underground method. At the same time, choosing the
location of mining shafts is always a difficult task when you
need to choose between safety and economic efficiency. This paper is a step in solving the urgent problem, according to the authors, the solution of which is to develop a method for assessing and predicting changes in the state of the main opening workings of the field during operation.
Due to the close proximity of the mine shafts of the Gaisky
GOK to the sides of the quarry, it became necessary to monitor the vertical deformations of the shaft axis, which has been carried out since 2014. In our studies, the main goal was to identify vertical deformations of the shaft axis. On the basis of direct instrumental measurements of linear
parameters at the underground mine of the Gaisky GOK,
regularities of the formation of the deviation of the axis of
the shaft of the mine “Kletevaya” towards the worked-out
space were revealed. Determining the offset parameters of the axis of the Kletevaya mine shaft on the mined space of the open pit and underground mine is a complex multi-stage task, during the solution of which many factors should be considered. Based on the condition that the inclination of the barrel changes the measured linear parameters of the vertical axis. Changes in linear parameters at the observation station of all
horizons can be summed to obtain the total deviation of the
shaft in the area from 0 to -990 m. For monitoring, a methodology was developed for instrumental measuring the deviation of the shaft at various depths.
