Multi-dimensional monitoring borehole stress meter and monitoring method thereof

The invention relates to a multidimensional monitoring borehole stress meter and a monitoring method thereof, and belongs to the technical field of mine pressure safety detection. The borehole stress meter comprises an angle sensor, a multi-dimensional stress monitoring module and a one-way hydraulic cylinder, the stress monitoring module comprises a base and a jacking mechanism, the base is of a two-half-symmetrical cylindrical rigid structure, the jacking mechanism is arranged in the base, steel spring plates are fixed to the surface of the base, and a force measuring grating is installed on each steel spring plate; the rear end of the base is connected with a one-way hydraulic cylinder pushing jacking mechanism to push the jacking mechanism in the cavity of the base, so that the diameter of the sensor is increased. The angle sensor is arranged at the end of the borehole stressometer and used for monitoring the orientation of the sensor, and the 360-degree orientation detection function can be achieved; the
