摘要
采用2种矿井物探方法探明了工作面煤层中构造的发育情况以及构造在煤层底板的含/导水性。介绍了矿井槽波地震和音频电透视的基本原理和资料处理方法。根据工作面实际水文地质条件,研究采用槽波地震和音频电透视综合矿井物探方法进行探测。结果表明,槽波地震成果在煤层中发现陷落柱,音频电透视在陷落柱底板发育相对富水异常区。经过钻孔和回采揭露验证,槽波成果发现的陷落柱范围较准,横向精度较高;音频电透视成果在平面和垂向范围均较准。综合2种物探成果预测预报了回采工作面中构造及其含/导水性。研究为工作面防治水工作提供了参考。
Two kinds of mine geophysical prospecting methods were used to find out the development of structure in coal seam of working face and the water content/conductivity of structure in coal seam floor.The basic principle and data processing method of mine trench wave seismic and audio electric perspective were introduced.According to the actual hydrogeological conditions facing the working face,the geophysical prospecting method of the integrated mine with trough wave seismic and audio-frequency electric perspective were studied.The results showed that the collapse column was found in the coal seam by the trough wave seismic results,and the water-rich anomalous area was developed in the floor of the collapse column by audio-frequency electro-fluoroscopy.The results of drilling and mining revealed that the scope of collapse column found by trough wave results was more accurate,and the lateral accuracy was higher.The results of audio electro-fluoroscopy were more accurate in both plane and vertical ranges.The structure and its water-bearing/conductivity in mining face were predicted by synthesizing two geophysical prospecting results.The study provided a reference for the prevention and control of water in working face.
