摘要
Abstract
The karst and collapse column in the Limestone region seriously affected the choice of the location of coal re-sources exploration drilling and coal mining have had a late safety hazard.In order to avoid the impact of these adverse geolog-ical factors,the paper applied a method to investigate these issues according to these unfavorable geological geophysical charac-teristics,distribution,morphology audio magneto-telluric method of choice in a coal exploration area of formation water,ca-ves and sink hole formation,development scale and depth of burial.Finally according to the method of interpretation results de-lineated the collapse column,buried karst,and fracture development zone is verified by the late drilling.The survey result is an audio magneto-telluric method in limestone karst areas,survey collapse column adds a success case.关键词
