封孔质量的好坏,是探矿工程六项指标之一。当前封孔材料有水泥浆和粘土两种。吉林省6101地质队,针对目前两种封孔材料,结合本队情况,设计了构造简单、操作方便、野外队均可制造加工、经济适用的水泥浆和粘土封孔工具。经试验,这种工具封孔质量高,成本低。现分别介绍如下,以供参考。 Sealing quality is one of the six indicators of prospecting engineering. At present, there are two types of plugging materials, cement paste and clay. Jilin Province 6101 Geological Team, for the current two kinds of sealing materials, combined with the team’s situation, designed a simple structure, easy operation, field teams can be manufactured and processed, economical cement slurry and clay sealing tools. After testing, this tool has high sealing quality and low cost. The following are separately introduced for reference.
