摘要
顶板水害严重制约煤矿安全绿色开采。本研究基于直流电法对铁迈煤矿11050工作面顶板0~80 m层段进行立体勘探,依据电阻率异常,将顶板水划分为高、中、低、无四级。物探结果显示,顶板上16、30、50 m异常富水区面积占比分别为49.74%、61.86%、41.25%,推测30 m范围为主要富水区且存在老窑水;结合钻孔疏放水量统计显示,16~30 m、30~50 m、50~80 m层段疏水量分别为1308、14154、2563 m^(3),进一步结合地质资料与物探成果,判定0~30 m及50~80 m主要为裂隙水,30~50 m主要为老窑水,其中老窑水占78.52%,裂隙水占21.48%。研究成果为矿井防治水及直流电法应用提供了参考。
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 1308 m^(3),14154 m^(3) and 2563 m^(3),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.
