微动探测技术在老挝万象盆地钾盐勘查及水害防治中的应用
Application of Microtremor Survey Technology in Potash Exploration and Water Hazard Prevention in the Vientiane Basin,Laos
摘要
Abstract
Most potash mining areas in the Vientiane Basin of Laos have completed exploration and entered the stage of conversion from exploration to mining.Affected by salt tectonic deformation,the potash deposits in this area feature complex stratigraphic structures with evident stratum hiatus and abrupt variation.During roadway development,saturated brine frequently forms at the contact zones between mudstone and rock salt on the roof and floor of potash seams,which may easily trigger water inrush accidents and pose a serious threat to mine safety.The research team adopted the microtremor survey technology to conduct potash exploration tests in the Vientiane Basin.The ore-bearing layers and aquifers were interpreted in detail,and the thickness,burial depth and spatial deformation characteristics of mudstone and rock salt of the Thakong Formation were clearly identified.The interpretation results are in good agreement with drilling verification data.Meanwhile,microtremor detection technology was applied to accurately delineate water hazard risk zones in the Vientiane Basin,effectively detect water-conducting and water-filling channels,and summarize the distribution pattern of water-rich areas.The research findings provide a reliable basis for roadway design and safe mining in potash mines.They hold significant engineering importance for predicting ore layer conditions,preventing water inrush and roof collapse accidents,ensuring production safety,and reducing economic losses.关键词
