隔离含水层的方法很多,在各个不同的地区或不同的岩层中所采取的方法也各不相同。我们在宣龙式铁矿的大岭堡、麻峪口等矿区的震旦纪坚硬裂隙岩层中作分层抽水试验时,曾试用了利用膠皮或牛皮来隔离含水层,经证明不但经济、方便,而且效果良好;尤其是在具有高压水头的坚硬裂隙地层中.较其他方法均为优越;在一个钻孔中作多层含水层的长期观测,亦能收到预期的效果,现将其操作步骤和要求介
There are many ways to isolate aquifers, and the methods used in different regions or different rock formations vary. When stratified pumping tests were conducted in Sinian hard rock fractures in the mining areas of Dalongbao and Mayukou of the Xuanlong Iron Mine, we tried to isolate the aquifer by rubber or leather, which proved to be not only economical and convenient , And works well, especially in hard-fissured formations with high-pressure heads, which is superior to other methods. Long-term observations of multiple aquifers in a borehole also receive the expected results. Steps and requirements referrals
