[0021] For example, see Figure 1-Figure 3 and Figure 6-Figure 7 The present invention provides a technical solution: a three-way pressure monitoring device for mining, comprising a housing 1, a guide hole 105 is opened on the outer wall of the housing 1, a guide sleeve 101 is fixedly connected to the inner wall of the housing 1, a detection block 103 is fixedly connected to the inner wall of the housing 1 through a support plate 102, and a guide block 104 is fixedly connected to the outer wall of the guide sleeve 101, and further comprising: The pressure mechanism 3 is arranged on the outer wall of the detection block 103.

The groove wall of the sliding groove 305 is fixedly connected to a limiting block 308. A compensation rod 303 is slidably connected to the inner wall of the pressure rod 301. The ball head of the outer wall of the compensation rod 303 is connected to an adjustment block 304. A guide groove 306 is arranged on the outer wall of the compensation rod. A spring 307 is fixedly connected to the outer wall of the compensation rod. The other end of the spring 307 is fixedly connected to the outer wall of the guide block 104. A support mechanism 2 is arranged on the top of the adjustment block 304. A thrust assembly 4 is arranged on the outer wall of the compensation rod.

The guide sleeve 101 is used to guide the compensation rod 303 and limit the pressure rod 301. 03 The support plate 201 is supported by adjusting block 2 304. When the geological structure of the mine changes and the support mechanism 2 is subjected to pressure in the tilt direction, the support mechanism 2 in the force direction tilts, driving the support mechanisms 2 in other directions to tilt at the same time, and disassembles the pressure in the tilt direction into multiple strands and bears the corresponding pressure mechanisms 3. At the same time, the support mechanism 2 is deformed, resulting in a larger range of distance measured in other directions. At this time, the compensation rod 1 303 is squeezed by spring 2 307 to make the compensation rod 1 303 slide on the inner wall of the guide sleeve 101.
