伞型钻架和中心回转抓岩机在某铀矿冶工程336竖井施工中的应用

摘要

Umbrella-type drilling frame and centre-rotary grab loader were used in the No.336 shaft construction of a uranium project to speed up the construction progress.Practice shows that the construction time was shortened and the labor intensity of workers was significantly reduced by using umbrella-type drilling frame and centre-rotary grab loader with good results.%打眼爆破和出渣是竖井基岩施工中决定进度的重要环节.在某铀矿冶工程336竖井施工中采用了伞钻和抓岩机施工技术,使竖井基岩施工进度大大加快.实践表明,这项技术在该工程施工中的应用是成功的,为今后铀矿山竖井施工应用这项技术积累了经验.
