为实现对煤矿含水异常体的井下精细化探测,基于煤矿含水异常体类型划分及特点分析,研究了矿井物探方法特点及适用条件,并结合综合物探应用案例进行了分析。结果表明:煤矿含水异常体可分为突水水源和导水通道2大类;煤矿含水异常体精细综合物探应采用2种或2种以上的物探方法,做到地震类方法与电磁类方法相配合、同类物探方法相补充;矿井物探方法主要分为矿井电磁类方法和矿井地震类方法,矿井综合物探勘查可以按掘进头超前探测、工作面内部探测、顶底板探测进行分类,应根据含水异常体类型和特点选择适合的矿井综合物探方法;案例表明了综合物探具有良好的应用效果。
In order to realize the downhole fine detection of abnormal water bodies in coal mines, the characteristics and applicable conditions of the geophysical exploration methods are studied based on the classification and characteristics of abnormal water bodies in coal mines. The results show that coal-bearing anomalous water bodies can be divided into two categories of inrush water and water-conducting channels. Two or more geophysical methods should be adopted for fine-grained geophysical exploration of water-bearing anomalies in coal mines so that seismic methods and electromagnetic methods Geophysical methods of mine are divided into methods of mine electromagnetism and methods of mine earthquakes. Mine comprehensive geophysical prospecting can be classified according to advance detection of excavation head, detection of internal working face and detection of roof and floor, Body type and characteristics of the appropriate choice of mine geophysical prospecting method; case shows that the comprehensive geophysical prospecting has a good effect.
