海带固定套管技术在临时探放水中的应用

Application on Using Kelp to Fix Casing in Temporary Prosepecting and Drainage Water

在煤矿临时探放水工作中,孔口保安套管的固定最为关键。马兰矿对孔口保安装置、固管工艺进行了改进,使用海带固定套管,经多次试验应用,海带固定套管技术可缩短工期、简化工艺、且止水固管效果好。

In the temporary prospecting and drainage water of coal mine,it is the key to fix the safety casing in the top of drilled hole.Malan mine improves the safety device in the top of drilled hole and technology,uses kelp to fix casing.Many experiments prove that the technology of fixing casing with kelp can shorten project time limit,simplify craft.The effect to water-seal is better.
