天(溜)井工程是井下金属矿山基建、采矿的重要工程之一,其工程量约占矿山井巷工程总量的10％～15％。天(溜)井施工断面狭小,属井内高处作业,施工人员受炮烟、落石和粉尘的威胁。从梅山铁矿一期工程和其它矿天(溜)井施工实践来看,由于天(溜)井施工所致的工伤事故在矿山工伤事故中所占的比例较大,因此,搞好天(溜)井施工安全管理,保证安全生产,是我矿安全管理工作中的重要课题。近几年来,我们
Day (slipped) well engineering is one of the important projects of underground metal mine infrastructure and mining. The project volume accounts for about 10% -15% of the total mine shaft and tunnel project. Day (slipped) well construction section is small, is a high-altitude operations, construction workers by the smoke, rockfall and dust threat. From the first phase of the Meishan Iron Mine and other mining (slippery) well construction practice, due to the days (slip) wells caused by work-related accidents in the proportion of work-related accidents in the mine, so do a good day Slip) well construction safety management, to ensure safety in production, mine safety management is an important issue. In recent years, we
