3308 运输巷掘进期间会揭露空巷,在穿越空巷时顶板岩层稳定性较差、容易出现冒落问题。为此,针对现场实际条件对过巷道过空巷掘进技术以及围岩控制技术等进行详细参数,并进行工程应用。现场应用后,空巷顶板岩性变形量控制在 15mm 以内,取得较为显著的应用成果。研究成果可为其他矿井掘进巷道过空巷围岩控制工作开展提供经验借鉴。“,”The empty roadway will be exposed during the tunneling of the 3308 transport roadway. When crossing the empty roadway, the roof rock layer has poor stability and is prone to caving problems. For this reason, according to the actual conditions of the site, detailed parameters of the tunnel driving technology and surrounding rock control technology are carried out and applied in engineering. After the field application, the lithological deformation of the empty roadway roof is controlled within 15mm, and more significant application results have been achieved. The research results can provide experience and reference for the development of surrounding rock control work in other mine tunnels.
