竖井是随时都可能发生灾难性事故的主要场所之一。1987年4月,国际镍公司汤姆森镍矿成立了第一个竖井安全作业服务队,最初由8人组成:设备司机、矿井工长、工程技术人员、维修人员和矿长。该队称为“竖井风险分析队”(SRAT)。由于在竖井内需完成的工作很多,服务队把工作划分为6个主要工序:吊挂钢绳、运送人员、箕斗装卸、排水、井筒检查和运送材料。了解它们相互关系的唯一方法就是把完成的作业步骤制成操作程序图表。该操作程序图是工长和设备司机利用现有的标准手册和他们的实际生产经验制订的。 The shaft is one of the main places where a catastrophic accident may occur at any time. In April 1987, the International Nickel Company Thomson Nickel Mine opened the first shaft safety service team, initially consisting of eight people: equipment drivers, miners, engineers, maintenance personnel and mine managers. The team is called the “Shaft Risk Analysis Team” (SRAT). Due to the large amount of work to be done in the shaft, the service team divided the work into six main processes: hanging ropes, transporting personnel, skip loading and unloading, drainage, well inspection and shipping of materials. The only way to understand their relationship is to make the completed job step into a chart of the operating procedures. The operating procedures map is the foreman and equipment drivers to use the existing standard manual and their actual production experience developed.
