Abstract: In view of the problems of strong cutting disturbance, lagging support, lack of control and protection and others during the excavation and anchoring construction process under the 3302 transportation roadway weak surrounding rock condition of Haitian Coal Industry, a technical system of "surrounding rock disturbance response-support time matching-equipment function adaptation" is constructed. Five items of key technologies, including low disturbance cutting, empty top distance control and support, multi-dimensional collaborative support, integrated drilling and anchoring, and coal side spraying control and protection are proposed. An integrated excavation and anchoring machine with small empty top distance operation capability is developed. Through industrial testing, it is verified that when the empty top distance is controlled to 0.5 m, the support cycle is decreased from 45 minutes to 27 minutes, and the efficiency is improved by 40%; The excavation efficiency is increased from an average of 200 m per month to 410 m per month, with an improvement of approximately 95%; The support accident rate is decreased from 0.026 times/m to 0.004 times/m, with a decrease of 85%. This system achieves a closed-loop operation mechanism of "synchronous excavation and support-rapid closure", provides a complete set of technical path and demonstration scheme for safe and efficient excavation of coal roadway surrounding rock under the "three soft" condition.
