摘要
为探查潘北矿-580 m水平C3Ⅰ组灰岩含水层水力联系状况,以及其主要断层DF13的导、阻水性,采用基于电位分析的连通试验方法,通过在地表长观孔投入碘化钾示踪剂,在井下-580 m放水大巷放水孔采集水样,监测水样的电位值随时间变化特征来判断示踪剂接收情况。研究查明了C3Ⅰ组灰岩水的运动特征和运移通道,包括流向、平均流速等。
In order to probe the hydraulic relation status of limestone aquifer in group：C3I, 580 m underground of Panbei coal mine and the hydraulic property of the main fault DF13, connection test, based on potentiometrie analysis, was ;adopted, through which, potassium iodide was put into the surface long-time observation hole as a tracer to monitor the characters of potential values of samples connected in drain hole 580 m underground over time so as to estimate the reception of the tracer.This study deals with the motion feature and migration pathway of limestone water in group C3I, including flow direction, mean velocity, etc.
