高密度电法在采矿塌陷区地质探测中的应用研究
|
摘要
高密度电法在近年来在采矿塌陷区探测中应用广泛,高密度电法具有点距密,浅部分辨率高,工作效率快的特点。在治理采空区塌陷等地质灾害时,勘探到采空区位置显得尤为重要,结合地质资料,根据剖面垂向电性结构变化特征,推测区内软弱矿层的空间分布、形态、规模,第四系覆盖层厚度,经研究发现高密度电法对采空区的塌陷情况进行探测,效果良好。
High density resistivity method has been widely used in mining subsidence area detection in recent years. It has the characteristics of dense point spacing, high resolution in shallow part and fast working efficiency. When dealing with geological hazards such as goaf collapse, it is particularly important to explore the location of goaf. Based on the geological data and the vertical electrical structure change characteristics of the section, the spatial distribution, shape and scale of weak ore layers and the thickness of Quaternary overburden in the area are inferred. It is found that the high-density electrical method is effective in Detecting Goaf collapse.
