Translation:

Through testing, the maximum horizontal principal stress was found to be between 13.13-22.74 MPa, and the rock strength stress ratio was between 4.39-7.62. This indicates a medium to high stress region. The direction of the maximum horizontal principal stress was N67°W to N69°W, with an average of N68°W. This intersects with the initial planned factory axis of N13.7°E at a large angle (82°), and intersects with the main structural plane at a small right angle of 30°. This has some adverse effects on the stability of the surrounding rock of the underground factory. Therefore, it is necessary to analyze the proportion of structural stress, investigate the orientation of structural planes in the factory area, and further study the necessity and possibility of adjusting the axis of the underground tunnels. Furthermore, construction monitoring and support should be strengthened, and attention should be paid to the unloading and stability of the surrounding rock of the underground tunnels during construction.
