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