Abstract The size and direction of ground stress determine the deformation and stability of underground coal-rock mass. Therefore，it is of great significance to study the real-time ground stress measurement technology for monitoring coal-rock dynamic disasters. In this study，a three-dimensional stress sensing device based on the principle of hydrostatic pressure was developed，and its stress sensing performance was tested and analyzed. Meanwhile，the solution formula of three-dimensional ground stress was analyzed. In addition，the size and direction of three-dimensional stress of Shoushan No.1 Coal Mine were measured and calculated by installing two sets of stress sensors. The results show that the stress sensed by the device is linearly related to the actual load stress，with a correlation coefficient of 0.989 57，the sensing spring plates of three-dimensional stress are mutually independent. The maximum principal stress of the mine is 22.86 MPa，the azimuth is 140°，and the dip angle is 2°，the ground stress is dominated by horizontal stress，the side pressure coefficient is 1.22. It was a typical tectonic stress field. The test results agree with the results of previous studies. The results show that the three-dimensional stress sensing device and method proposed in this study are not only simple and easy to operate，but also able to accurately measure the size and direction of ground stress. They have bright prospect in engineering applications.
