摘要
为了查清岩层中含水层发育情况,为矿井施工和开采提供安全保障,采用井液电阻率测量技术,利用井液电阻率曲线随时间变化产生的离差现象,绘制离散曲线,通过分析计算,查明地下水运动状态,判别含水层类型,并确定含水层位置和涌水量。实例测量结果表明,该方法能有效查明含水层发育情况,可为矿井设计、施工提供防治水技术参数。
In order to find out the development of aquifer in rock strata and provide safety guarantee for the construction and exploitation of the mine,the discrete curve was drawn by using the measurement technology of the drilling fluid resistivity and the deviation phenomenon produced by the change of the drilling fluid resistivity curve with time,and through the calculation and analysis,the movement state of groundwater was found out,the type of aquifers was distinguished and the location and the water inflow of the aquifer were determined. The measurement results showed that the development of the aquifer can be effectively identified with this method,so it can provide technical parameters for water control in mine design and construction.
