钻孔流速仪或钻孔测漏仪(以下简称孔速仪)应用于水文地质工作以后,取得了一定效果。它能够近似地测出漏水位置,自流含水层的下界面,条件许可时,还能判断含水层的厚度。我们在两个矿区主要使用Zbc—2型仪,该仪器由孔内测头和地面数字显示两部分组成。一、钻孔注水时的测定孔速仪的设计原理是通过孔内水的垂向运动,带动测头的叶片旋转,并将每转一圈的信息输送到计数器中,以此判定地下水垂向运动速度状况。即通过转数的缓变或突变
Drilling hole velocity meter or hole leak detector (hereinafter referred to as hole meter) applied to hydrogeological work, and achieved some results. It approximates the location of water leaks, the lower interface of the gravity aquifer, and the thickness of the aquifer when conditions permit. We mainly use Zbc-2 instrument in two mining areas. The instrument consists of two parts: the probe in the hole and the digital display on the ground. First, the determination of drilling water injection Pore measuring instrument design principle is through the hole in the vertical movement of water, driven by the blade rotation of the probe, and each turn of information delivered to the counter, in order to determine the vertical groundwater Movement speed condition. That is, through the slow change or mutation
