description Abstract In order to alleviate the problem of tense mining succession in coal mines, this study starts from the perspective of rapid roadway excavation roadway support efficiency, and researches on the mechanism of anchored drilling drilling for drilling and rock breaking, establishes the functional relationship equation between the drilling bit cutting rock-breaking force and the energy required to break the unit volume of rock, and verifies the drilling through numerical simulation, self-research drilling experiments on different lithologies and parameters of drilling with drilling, and collects the feedback parameters of displacement, rotational speed, thrust, and torque drilling against theThe feedback parameters of displacement, rotational speed, thrust and torque drilling were collected and analyzed.The research results show that the average speed of drilling, the rotational speed of the drill bit and the rock strength have a negative correlation trend, and the thrust and torque have a positive correlation trend with the rock strength, and the feedback signal of drilling can realize the judgment of the rock strength, realize the prediction of the structure of the surrounding rock, and improve the efficiency of the roadway support in the roadway of rapid excavation roadway support.
