【摘要】 针对焦作矿区的矿井水文地质特征并结合采掘情况,在演马矿、冯营矿、九里山矿和古汉山矿,分别选用音频电透、瞬变电磁、直流电法、地质雷达、无线电坑透仪、瑞雷波仪等技术对巷道和工作面采掘前方和顶底板的富水异常区进行了探测,其准确率达100%.评价了6种井下物探技术的适用条件及优缺点,现场井下探查时应尽可能采用2种以上的物探技术开展工作,以提高井下物探的准确率.更多还原

【Abstract】 According to the hydrogeological features and excavation situations in Jiaozuo mining areas of Yanma mining,Fengying mining,Jiulishan mining and Guhanshan mining,by means of an electric audio-clairvoyant method,a transient electromagnetic method,a direct current method,radio tunnel instrument,a radio mine locator system and realign wave,and etc,the excavation frontages of roadway and working face and the rich water anomaly areas of roof and floor were explored,and the accuracy could reach 100%.In addition,the adaptable conditions and the pros and cons of the above six underground geophysical exploration technologies are evaluated,and in order to improve the accuracy of underground geophysical explorations,more than two geophysical technologies should be adopted as soon as possible in the fields.更多还原
