Geostress measurement is a necessary prerequisite for determining the attributes of engineering rock body mechanics, analyzing the stability of the surrounding rock, and realizing the scientific excavation design and decision-making of rock engineering. With the depth of mining of Mianhuakeng mine, the impact of complex structural stress on the stability of the lane roads and lying surrounding rocks has become increasingly apparent. In order to master the terrain distribution of the rock body in the deep part of the mine and improve the scientific, safety and economic rationality of the underground engineering design, the hollow inclusion stress relief method is used to carry out the stress measurement of the mine, and analyze its stress status and distribution rules. The results show that the maximum main stress is between 22.5 and 29.8 MPa and the ratio of the maximum main stress to vertical stress is 1.5 ~ 1.7 in the buried depth of 615~715 m. The main stress increases linearly with the depth and the maximum main stress direction of each measurement point level is in the direction of from 91.2 to 110.3° (North West West-South East East), which has a strong consistency.
