摘　　要：为有效提高新型封孔材料封孔作业的安全性,采用作业条件危险性分析的安全风险辨识方法,辨识封孔作业过程中的危险源;采用安全风险评估指标体系,将封孔作业细分为7个一级风险因素指标及34个二级风险因素指标;定量计算各指标因素的关联度及危险程度;采用安全检查表法检查封孔作业整个过程的“人-机-环-管”系统安全。研究结果表明:压风管路崩裂、顶板冒落、风动搅拌桶扇叶、新型材料腐蚀及注浆出料口堵塞憋压是钻孔封孔作业重点管控的风险因素;采用安全检查表法可全面筛查封孔作业前、作业中和作业后的风险。In order to effectively improve the safety of sealing operation of new sealing material,the safety risk identification method of hazard analysis of operating conditions was adopted to identify the danger sources in sealing operation.The safety risk assessment index system method was adopted to subdivide the sealing operation into 7 first-level risk factor indexes and 34 second-level risk factor indexes.The correlative and dangerous degree of each index factor was quantitatively calculated.The safety checklist method was adopted to check the safety of"human-machine-environment-management"system during the whole process of sealing operation.The safety checklist method was used to check the safety of the"human-machine-environment-management"system in the whole process of the operation.The research results show that cracking of pressurized air pipeline,falling roof plate,fan blade of air-driven mixing drum,corrosion of new materials and blockage of grouting outlet to hold the pressure are the risk factors that are important to be controlled in the drilling and sealing operation.The safety checklist method can be used to comprehensively screen the risks before,during and after sealing operations.
