直流电法探测技术在彬长矿区防治水中的应用

为解释工作面顶板砂岩水的赋存位置,评价工作面内部隐伏导水通道上下联通情况以及工作面内部钻孔导水性,胡家河煤矿采用直流电法探测技术开展了防治水实践。首先介绍了直流电法探测技术的原理、工作方法,针对具体的地质任务选择合适的装置及施工参数,进行了数据采集和整理。根据现场调查资料,对个别发生畸变的极距点数据进行圆滑或剔除处理,将所得合格数据进行反演解释,确定工作面内部及顶板的水文地质情况。实践表明,直流电法勘探是煤矿井下水文探测较为理想且行之有效的物探方法之一,可以运用于煤矿井下防治水工作,为煤矿安全回采提供有效的技术支持。

The application of DC detection technology in water prevention and control of Binchang mining area

In order to explain the existing position of the sandstone water in the roof of the working face,evaluate the connection conditions of the concealed water diversion channel and the water conductivity of the borehole in the working face,the direct current electricity detection technology was used in the water prevention and control practice in Hujiahe mine.According to the principle and working method of DC electric detection technology,according to the specific geological task,the appropriate equipment and construction parameters were selected and the data collection and sorting were carried out.According to the field survey data,the individual data were processed,the qualified data were inverted and interpreted,and the hydrogeological conditions of the working face were determined.The practice shows that the direct current electric method is one of the ideal and effective geophysical methods for the detection of underground water in coal mines,which can be applied to the prevention and control of water in coal mines and provide effective technical support for the safe mining of coal mines.
