分段压水试验在东平大牛矿区水文地质勘查中的应用

Application of Segmented Water Pressure Test in Hydrogeological Exploration in Daniu Mine in Dongping County

摘要:

压水试验方法同样适用于矿区水文地质勘查的各阶段，特别是针对透水性不是很大的矿区，选择单管栓塞压水试验方法，有使用方便、操作简单、灵活易行、不受孔径限制等独具的特点。在同一钻孔中进行分段压水试验，计算各段的透水率、渗透系数，根据各段渗透性对矿区含水层、段进行划分，为矿区水文地质条件划分提供依据。

Abstract:

The water pressure test method is equally applicable to mine hydrology geological prospecting in each stage, especially for mining areas with less water permeability. Single tube embolization water pressure test method has the characteristics of easy to use, simple operation, and not restricted by aperture. Water pressure test has been carried out in the same borehole. Permeable rate and the coefficient of permeability of each section have been calculated. According to different permeability, waterbearing strata and parts have been divided. It will provide a basis for the division of hydrogeological conditions in mines.
