【摘要】 老挝甘蒙省地区广泛分布钾镁盐矿矿床,其矿床属于可溶性固体钾镁盐矿类型,矿层主要分布在新生界古近系盐层中,矿物主要以钾石盐、光卤石为主。通过对此处可溶性固体钾盐工程地质特征的系统分析研究,探索出了一套适用于可溶性固体钾镁盐矿的钻探施工工艺,特别是对矿心采取和保护、漏失预防及治理,以及最终的封孔工艺进行了深入的研究。更多还原

【Abstract】 K-Mg salt deposit is widely distributed in Gammon Province of Laos,which belongs to soluble solid K-Mg salt deposit,the ore seams mainly spread in Cenozoic paleogene salt bed and mainly with sylvite and carnallite.By the systematic analysis on the engineering geological characteristics of soluble solid K-Mg salt,a set of drilling construction technology in soluble solid K-Mg salt deposit was probed out.The study on coring and core protection,leakage prevention and the control and borehole sealing technology was presented.更多还原
