金属矿山提升过卷保护装置的应用与探讨

Application and Discussion on Hoisting Overwinding Protection Device of Metal Mine

针对国内金属矿山规范中对竖井过卷保护装置的具体规定,结合国外工程项目实例,分析了竖井提升常用过卷保护装置楔形罐道、机械式过卷保护装置的结构原理及计算方法,并对几种过卷保护保护装置的特点进行了分析对比,对我国现行金属矿山规程、规范关于过卷保护的规定提出了探讨性建议。

According to specific provisions of shaft overwinding protection device in national metal mine code and example of overseas engineering project, the paper analyzes structure principles and calculation method of overwinding protection device wedge cage and mechanical overwinding protection device used for shaft hoisting, and compares characteristics of several overwinding protection devices, and puts forward suggestions on overwinding protection provisions in the current national metal mine codes and regulations.
