概况河南省焦作市博爱县水利局打井队在672储备库区打了一眼φ35厘米的机井,深150米,含水层在110～137米之间。井筒从2米至150米深处全为致密的石灰岩,裂隙很少,影响了机井井水的来源,机井的出水量仅为原设计的三分之一。为了扩大水源,加大水量,现采用在含水层处用爆破的方法来扩展裂隙。 At a glance Drilling team of Boai County Water Conservancy Bureau of Jiaozuo City, Henan Province, drilled a φ35 cm machine well at a reservoir area of ​​672 reserve, with a depth of 150 meters and an aquifer of 110 to 137 meters. The wellbore is densely packed limestone from 2 meters to 150 meters deep, with very few fissures that affect the source of well water, which is only one third of the original design. In order to expand the water source, increase the amount of water, is now used in the aquifer blasting method to expand the cracks.
