摘要
介绍了采用矿井高分辨直流电法勘探方法对Ⅲ625工作面进行水文地质探测的主要成果,查清了6煤底板下60m内的主要含水、导水构造的分布规律,对6煤底板下隔水层厚度、富水性及上下连通情况等作出了定性评价,并对潜在导水通道作出正确预测,从而有针对性地治理水害,保证了Ⅲ625工作面安全开采。
It introduced achievement of adopting the method of High - Distinguished Direct Current in mines to have hydrogeology exploring on Ⅲ 625 work face, and checked the distributed regulations of primary containing water and leading water construction in 60m under No.6 coal scaleboard with the method;made a qualitative evaluation to water-resisting layer, watery and connected cir-cumstance up and down etc. under No. 6 coal sealeboard, makes accurate predicts to latent leading water passway. Thus the water damage was controlled pointedly and safety mining on Ⅲ 625 work face was ensured.
