七宝山硫铁矿小生产区170暗斜井提升运输系统,于1978年5月投产以来,已提升矿岩54.75万车,达到了设计能力。并相应的通讯信号、控制设备、安全装置等设施及安全管理制度相继完善。 为探索开创安全工作新局面,笔者以本暗斜井提升五年间的事故统计资料为依据,试图运用安全系统工程的基本原理,进行安全可靠性分析。以预测今后为保证安全生产,实现较高经济效益的安全工程技术体系。 (一)运输系统的结构 了解一个系统各单元的工作关系是分析安全可靠性的先决条件。图1是170暗斜井
Qibao Mountain Pyrite production area 170 dark inclined shaft hoisting and conveying system, put into operation in May 1978, has raised 547500 vehicles, reached the design capacity. And the corresponding communication signals, control equipment, safety devices and other facilities and safety management system have been improved. In order to explore the new situation of creating safety work, based on the statistic data of accidents caused by the improvement of this dark inclined shaft in five years, the author tries to apply the basic principle of safety system engineering to carry out the analysis of safety and reliability. In order to predict the future to ensure safe production and achieve high economic efficiency of security engineering and technology system. (A) the structure of the transport system Understand the working relationship between the various units of a system is a prerequisite for the analysis of safety and reliability.
