Abstract
Faults, collapse columns in coal strata will not only destroy the integrity of coal bed , reduce recoverable reserves , but also affect the production safety of coal mines , and cause serious harm in coal mining .It has great significance to identify the distribution of faults and collaspe columns within the exploration area , and its hydraulic conductivity in the early period of coal mining .On the basis of collecting geological , hydrological and geophysical data of the first mining Ⅰarea in Licun coal mine , using transient electromagnetic technology , hydraulic conductivi-ty survey of faults and collaspe columns in this area have been studied and achieved good results .It will provide some references for the design and construction of coal mining , and effectively prevent the occurrence of safety acci-dents in the coal mining process .关键词
