去年我局第三地质大队七号机在二道沟金矿施工，使用了广东地矿局探矿厂生产的DUJ-1型钻进故障报警自动提升装置，通过在两个孔的使用，共进尺500.31米，防止了三次烧钻事故，使用效果良好，深受机台工人的欢迎。第一次在ZK504号孔，当钻进至345米时，该装置突然报警，同时将钻具自动提离孔底。经提钻检查发现钻头有快要熔化的趋势，其原因是钻杆中部有三处漏水，冲洗液假循环没有到达孔底。
Last year, Bureau III of the Third Geological Brigade in Erdaogou gold mine construction, the use of the Guangdong Bureau of Geology and Mineral Resources prospecting plant DUJ-1 type drilling failure alarm automatic lifting device, through the use of two holes, a total footage 500.31 meters, to prevent the three burns accident, the use of good results, deeply welcomed by the machine workers. The first time in ZK504 hole, when drilling to 345 meters, the device suddenly alarm, while the drill automatically lift off the bottom of the hole. Drill bit inspection found that there is a tendency to melt the drill, the reason is the middle of the drill pipe there are three leaking, flushable liquid circulation did not reach the bottom of the hole.
