摘要
为保证矿井提升系统的安全稳定运转,文章对矿井提升系统存在的安全问题进行了详细的分析与总结.主要介绍了矿井提升系统振动冲击限制技术,立井提升系统过卷防治技术,矿井提升系统松绳、跑车事故防治技术,深井提升钢丝绳失效研究及防治技术,立井特大罐笼全无轨运输防偏载及锁罐技术和摩擦式提升系统打滑事故防治技术,最后进行了立井提升系统卡罐事故分析.针对矿井提升系统存在的相关安全事故,分析了各种问题的动力学特性,得出了研究结论,并针对提升系统的安全问题,对国家标准、规范提出了相应的修改建议,给出了具体的对策措施.
Abstract
To ensure the safe and stable operation of the mine hoisting system,the safety issues in the mine hoisting system are analyzed and summarized in detail.The accidents prevention and control technologies for underground mine hoisting system are introduced,such as the vibration impact limiting,overwind,rope loosening control,mine car runaway control,rope failure control in deep well hoisting,eccentric loading prevention and locking of the trackless transportation of the large vertical shaft cage,and the anti-sliding accidents prevention and control in the friction type hoisting system;also,the cage stucking accidents in the vertical shaft hoisting system is analyzed.Aiming at the safety accidents related to the mine hoisting system,the dynamic characteristics of the various problems are analyzed.Finally,to address the safety issues of the hoisting system,corresponding modifications are proposed on the basis of national standards and specifications,and specific countermeasures are given.
