矿井音频电透视探水技术应用及效果

Audio frequency electric perspective exploring water technology performed and the effect in coal mines

二叠系山西组3煤顶板砂岩、侏罗系蒙阴组底部砾岩含水层是济宁三号煤矿开采上组煤主要充水含水层,富水性不均一。提前探查并正确处理上覆含水层富水区是确保矿井安全生产、提高生产效率的重要工作之一。近年来,应用矿井音频电透视技术探查采煤工作面顶板砂岩或侏罗系底部砾岩含水性异常的位置、形态及其含水相对强弱取得了比较理想的防治水效果。

Sandstone of Permian Period S ＂hanxi formation 3 coal roof, the bottom of Jurassic Period Mengyin formation is conglomerate aquifer which is the main water- filled coal aquifer when Jining NO.3 coal mining the higher seam, water - borne rich uneven. Early detection and correctly handle the overlying aquifers rich rearer area is one of the important work for the mine production safety and increase productivity. In recent years, the mine application audio frequency electric perspective exploring water technology exploration, coal face roof Jurassic Period sandstone or conglomerate aquifer at the bottom of abnormal position, shape and aquifer relative strength has been fairly good control water effects.
