A Study On Apparent-resistivity Anomaly Characteristic Of The Mined-out Area Influence To Ground Building Environment

The exploitation of mineral resources in a large scale has brought a lot of losses to environment and people's life. Mined-out area caused by mining not only influences the production and life of local people, but also restricts the sustainable development of the local economy. It even affects the relationship between the mine-manager and the local people directly and becomes unstable factor of our society.The basic data are obtained through open-field test based on apparent resistivity method.The obtained material data are reorganized and the contour of map apparent resistivity section is drawn. The contour of map apparent resistivity section anomaly morphological is analyzed combined with the periphery geological conditions of depletion region closely. The qualitative investigation and the quantitative interpretation to the anomaly morphological characteristics of the terrestrial electricity sectional map are carried on. The influence scope of the depletion region created by the surface construction environment is also analyzed quantitatively and cultivated according to the engineering geology theory. The selected influence scope corresponds to the actual scope excellently is confirmed through the actual example. Therefore, the study has a very bright application prospect in the future.
