Application of the high-density resistivity method to the investigation of underground mining airspace in the Laizhou mining catchment area
Shandong Laizhou area is rich in mineral resources,which greatly promotes the construction and development of the area,with years of mineral exploitation,a series of environmental geological problems have emerged. In order to improve and manage regional environmental geological problems,it is particularly important to select appropriate and efficient investigation methods for environmental geological investigations. The high-density resistivity method is an array resistivity exploration method with the advantages of low cost and high efficiency,which can greatly improve the efficiency of environmental geological investigation. This paper is based on the high-density resistivity method to carry out investigation work on the northwest iron ore mine and the surrounding area of Laizhou Sustainability Village,Shandong Province,to find out the geoelectric characteristics of the strata of the Sustainability Village,the spatial distribution characteristics of the underground air-mining zone,and the environmental geological problems such as the intrusion of underground seawater in the mine area. The results show:Sustainability and sustainability The area around the East Iron Ore Mine is subject to relatively severe seawater intrusion,and there is a wide-ranging open area at the depth of the iron ore mine;The groundwater in the area is relatively developed and salinised due to seawater intrusion,and there may be pseudo-anomalies caused by saline groundwater,which still need to be studied and verified by further work and drilling construction. The findings of the study can support the ecological restoration of iron ore mines.
