摘要
Abstract
Roof water disaster seriously restricts the safe and green mining of coal mine.In this study,based on the direct current method,the three-dimensional exploration of the roof 0～80 m layer of No.11050 Face in Tiemai Coal Mine was carried out.According to the resistivity anomaly,the roof water was divided into four levels of high,medium,low and no.The results of geophysical prospecting showed that the water abundance abnormal areas of 16 m,30 m and 50 m on the roof accounted for 49.74％,61.86％and 41.25％respectively.It was speculated that the 30 m range was the main water abundance area and there was old mining-out area water.According to the statistics of borehole drainage volume,the drainage volume of 16-30 m,30-50 m and 50-80 m layers was 1 308 m3,14 154 m3 and 2 563 m3,respectively.Further combined with geological data and geophysical exploration results,it was determined that 0-30 m and 50-80 m were mainly fissure water,and 30-50 m was mainly old mining-out area water,of which old mining-out area water accounted for 78.52％and fissure water accounted for 21.48％.The research results provided a reference for mine water prevention and control and the application of direct current method.关键词
