  • 摘要: 针对蒋庄煤矿副立井JKM3.25×4型多绳摩擦式提升机,结合现场核查、保护试验、检修台账和设备参数,从井筒装备、制动液压、电气拖动、保护联锁、钢丝绳摩擦、操车信号及管理档案7个维度系统识别风险因素。基于P、C、E三参数风险矩阵,明确风险评分依据、等级划分标准及关键单元评分流程,制定制动安全裕度、钢丝绳张力偏差率及速度控制等核心指标的评价阈值。研究提出“保护定期校验、制动系统精准维护、电控性能持续保障、钢丝绳全生命周期管理、隐患闭环整改”的五位一体管控措施,构建覆盖设备全生命周期的风险防控体系,为副立井提升机系统专项安全评价与动态管控提供量化标准与实施路径,可有效提升提升机运行安全性与可靠性。

     

    Abstract: Aiming at the JKM3.25 × 4 type multi-rope friction hoist in the auxiliary vertical shaft of Jiangzhuang Coal Mine, combined with on-site verification, protection testing, maintenance ledger and equipment parameters, risk factors are systematically identified from seven dimensions: wellbore equipment, brake hydraulic, electrical drag, protection interlock, steel wire rope friction, vehicle operation signal and management file. Based on the three parameter risk matrix of P, C, and E, the risk scoring basis, grade classification standard, and key unit scoring process are clarified, and evaluation thresholds for core indicators such as brake safety margin, steel wire rope tension deviation rate, speed control and so on are formulated. The research proposes a five in one management and control measure of "protection regular calibration, precise maintenance of braking system, continuous guarantee of electronic control performance, full life cycle management of steel wire rope, and closed-loop rectification of hidden dangers", constructs a risk prevention and control system covering the entire life cycle of equipment, and provides quantitative standards and implementation paths for special safety evaluation and dynamic management and control of the auxiliary vertical shaft hoist system, which can effectively improve the operational safety and reliability of hoists.
