Abstract:
When conducting research to determine the orientation of the main stresses, wells with a length of 2-3 mine diameters were used. With the help of a measuring probe included in the «Gidrofracturing» IVC, sections of the well were blocked and subjected to loading by injecting liquid into it until critical tensile stresses were reached, leading to rock rupture. For monitoring before and after hydraulic fracturing, a visual monitoring method using a downhole video probe was used. As a result of experimental studies to determine the effective stresses in the rock mass in the North-Western section of the Tashtagol mine using the method of measuring hydraulic fracturing, 14 tests were carried out at one measuring station. According to the data obtained by the visual method of determining the orientation of hydraulic fracturing cracks, at the measuring stations the action of the maximum principal horizontal stress has an azimuth of 280 ± 20°.
