Applications of the Electrical Resistivity Method for Detection of Underground Mine Workings
نویسنده
چکیده
The need to understand the location of abandoned workings has recently been highlighted by the failure of the Martin County Coal Corporation tailings impoundment near Inez, Kentucky on October 11, 2000 and the July 24, 2002 Quecreek Mine inundation that trapped nine miners for 77 hours in Somerset County, Pennsylvania. On a more routine basis, subsidence from abandoned mines represents a significant public cost in many states. Just in Pennsylvania, the State has invested over $100 million to address mine subsidence problems and estimates that 200,000 acres of high priority subsidence prone land still remain to be stabilized.

Surface Geophysical Methods for Detection of Underground Mine Workings
Efforts to delineate underground mine workings in the vicinity of tailings impoundments has relied on available maps and confirmatory boreholes. Often the characterization of regions between boreholes remains suspect or entirely unknown. Surface geophysical measurements can be used to supplement the borehole data and better delineate these intermediate zones. Furthermore, geophysics can be used...
متن کاملDetection and determination of groundwater contamination plume using time-lapse electrical resistivity tomography (ERT) method
Protection of water resources from contamination and detection of the contaminants and their treatments are among the essential issues in the management of water resources. In this work, the time-lapse electrical resistivity tomography (ERT) surveys were conducted along 7 longitudinal lines in the downstream of the Latian dam in Jajrood (Iran), in order to detect the contamination resulting fro...

Extended Abstract 1-Introduction Interdisciplinary studies play an important role in answering engineering questions. Identifying the characteristics of alluviums, underground water exploration and minerals, along with geotechnical studies in the construction of heavy structures are just some of these applications. Following the increasing drying of Lake Urmia, various research has been conduc...
متن کاملApproximate resistivity and susceptibility mapping from airborne electromagnetic and magnetic data, a case study for a geologically plausible porphyry copper unit in Iran
This paper describes the application of approximate methods to invert airborne magnetic data as well as helicopter-borne frequency domain electromagnetic data in order to retrieve a joint model of magnetic susceptibility and electrical resistivity. The study area located in Semnan province of Iran consists of an arc-shaped porphyry andesite covered by sedimentary units which may have potential ...
متن کاملAssessment of radioactive contamination in water bodies around mine workings using radiation counter
The vulnerability of water bodies to contamination within the neighbourhood of open mine cast environ cannot be overemphasized. Evidence of radioactive trace elements associated with the target minerals in the Plateau State (Nigeria) showed the extent of this vulnerability. In order to address this challenge, the radioactivity levels of water samples from mine ponds, streams, wells, and borehol...
