摘要
Abstract
The orebody No. 3 of a gold mine had been exploited by using openstope method. The production halted on December 4, 2006 because of the collapse accident of stope. In order to recover production and ensure the productive safety for the future, it is necessary to analyze the cause of caving and find out the actuality of fill-up. After geologic and stope investigation of the orebody No. 3, the cause of collapse is analyzed. Then the geophysical exploration technique, electromagnetic method, is used to detect the status of quarry. The exploration results not only open out the fill-up of dead zone, but also find out the abnormal zone of mineral deposit. It will be the evidence of recovery production and is recommended as reference to the future design.关键词
