Abstract: To explore the advanced support technology for large section gateroads, with the main transportation haulage roadway of 31205 working face in Cuncaota No. 2 Mine as the engineering background, a combination of on-site investigation, theoretical mechanics analysis, and FLAC numerical simulation was used to analyze the feasibility of replacing single hydraulic props with active advanced support. Based on the mechanism of active advanced control, a technical scheme of advanced support for reinforcement in the center of the roof was proposed. Field monitoring indicated that the maximum displacement of the roof, floor and two sides under active advanced support were 21mm and 23mm, respectively. According to the monitoring of anchor rod force, the anchor rod of active advanced support can be timely loaded. Moreover, the visual results showed that the integrity of the surrounding rock was good, which verified the feasibility of the scheme. This technology can meet the requirements of safe and efficient production, and promote the intelligent development of working face.
