煤峪口矿首采工作面复杂地质条件“四位一体”综合探测技术研究

Research on"Four in One"Comprehensive Detection Technology for Complex Geological Conditions in The First Mining Face of Meiyukou Mine

为进一步查清首采工作面构造及煤层赋存发育情况,首次采用井下探孔窥视结合测井技术、单巷槽波反射法、井下定向钻探技术、透、反射联合勘探法“四位一体”综合探测技术体系,避免了以往单纯地依靠钻探所造成的工作量极大且预测准确率较低的弊端,同时准确地预测断层及破碎带位置,保障煤矿安全高效生产。

In order to further investigate the geological structure of the first mining face and the development of coal seam occurrence,for the first time,the"four in one"comprehensive detection technology system was adopted,which includes underground exploration hole observation combined with logging technology,Single tunnel groove wave reflection method,underground directional drilling technology,and combined penetration and reflection exploration method.This avoids the drawbacks of relying solely on drilling in the past,which resulted in a large workload and low prediction accuracy.At the same time,it accurately predicts the position of faults and fracture zones,ensuring safe and efficient production in coal mines.
