[本刊讯]不久前,中国地质调查局勘探技术研究所(勘探所)膨胀管项目组在广西南丹马鞍山孔明银铅锌矿区ZK703孔Φ76mm孔段内,采用膨胀波纹管技术在1035m深处护壁成功。这是膨胀波纹管护壁技术首次应用于超深孔,为膨胀波纹管超深孔护壁打下了坚实的基础。膨胀波纹管护壁技术是由勘探所研发的解决各类钻探事故的一项护壁技术。该技术于2014年9月首次在四川宣汉地下100余米漏失段完成护壁堵 Not long ago, the expansion project of the Institute of Exploration Technology, China Geological Survey (Exploration Institute) project team was located in the Φ76mm hole of ZK703 hole in the Kumming silver lead-zinc mine in Ma’anshan, Nandan, Guangxi. The expansion bellows technology was used at a depth of 1035m Wall success. This is the first application of inflatable bellows wall technology in ultra-deep hole, expansion bellows ultra-deep hole wall to lay a solid foundation. Expansion bellows wall technology is developed by the exploration of all types of drilling to solve a barrier technology. The technology in 2014 September for the first time in Xuanhan, Sichuan 100 meters of the missing section to complete the wall blocking
