我矿坑口竖井有5个提升中段,提升高度为180m,采用钢丝绳罐道,2JK—2/20型提升机,3罐笼,安全制动系统抓捕器为GS型,缓冲绳和制动钢丝绳直径分别为43.5mm和28mm,由单绳连接器连接,如图1所示。设计作用在每根制动钢绳上的安全制动力约9.8kN。绳是用合金浇注在连接器内的锥形套中。因此,合金浇注的质量好坏直接关系到安全制动能否实现。 1.事故的经过和分析 1983年底,在提升设施安装调试完后进行了试生产。1984年2月正式投产。投产前的两 I pit mine shaft with five hoisting of the middle section, lifting height of 180m, using wire rope cans, 2JK-2/20 hoist, 3 cage, safety brake system for the GS-type arrestor, buffer rope and brake rope diameter Respectively 43.5mm and 28mm, connected by a single rope connector, as shown in Figure 1. The designed braking force on each brake cable is about 9.8kN. The rope is cast with an alloy in a conical sleeve inside the connector. Therefore, the casting quality is directly related to whether the safety brake can be achieved. 1. Accident and analysis After the end of 1983, after the installation and commissioning of upgrading facilities, the trial production was carried out. February 1984 formally put into operation. Two before production
