Abstract Mining-induced stress strongly influences coal mining safety. The magnitude of coal seamstress is one of the factors for assessing rockburst risk. This study aims to explore the relationship between drill pipe torque and mining-induced stress under the conditions of different constant rotation rates and drilling speed combinations. Through theoretical analysis and numerical simulations, the variation of mining-induced stress and drill pipe torque was systematically recorded in the drilling process, assuming that it maintains a consistent drilling speed and rotation rate. The results indicate that there is a positive correlation between the mining-induced stress and the torque. Thus, the measurement of the stress can be achieved by monitoring the torque.
