【摘要】 根据高密度电阻率法的工作原理、装置形式和异常特点,结合对华丰煤矿31105工作面底板含水体探测的实例,阐述高密度电阻率法在矿井含水层富水性评价过程中的应用,通过地电影像的图像显示,使得断面异常形态清晰明了。探查结果表明,31105工作面底板存在五个主要的徐、奥灰低阻异常,为底板水防治的重要部位。更多还原

【Abstract】 According to the fundermental theory, equipment formation and anomaly characteristics of HDRM (High-density Resistivity Method), the application of HDRM to the water abundance assessment of coal aquifer is discussed, which at the same time combined with a living example of aquifer exploration from the floor of No.31105 coal mining face in Huafeng colliery. By way of the picture of terrestrial electricity images, the abnormal sectional morphology is showed clearly. The result of exploration shows that five main low-resistivity abnormities exist in Xujiazhuang limestone or ordovician limestone in the No.31105 working face, which are the important parts of water prevention in working face floor.更多还原
