介绍了煤矿主、副井井筒内的罐道缝隙自动监测报警系统的设计思想、监测内容和设计方法。该系统可对安装在罐道梁上的每两个罐道之间的缝隙进行实时连续监测,具有缝隙闭合和缝隙扩大的报警功能,是保证罐笼或箕斗安全运行的一个重要监测环节,并为预测井筒的安全性提供了重要的数据。 The design idea, content and design method of the automatic monitor and alarm system of cannel gap in coal mine main shaft and auxiliary shaft are introduced. The system can monitor the gap between every two cans installed on the cantilever beams in real time and with the function of alarm of gap closing and gap enlargement, which is an important monitoring link to ensure the safe operation of the cage or skip. Provides important data for predicting wellbore safety.
