Combined application of integrated geophysical exploration in exploration of small mine roadway
WANG Peisheng
Abstract：The exploration of small mine roadway has always been a difficult point in engineering construction.Due to the incomplete-ness of mining data and the lack of management,the cost of exploring small mine roadway has greatly increased,and a little carelessness may even bury a great hidden danger for the buildings built above.In view of the difficulties in the exploration of the small mine road-way,a comprehensive geophysical exploration method combining the opposing coils transient electromagnetic method(OCTEM)and the ground penetrating radar method was used to explore the subsidence area in a certain site.Through the interpretation of comprehensive geophysical exploration and the establishment of a three-dimensional geophysical model,the trend and buried depth location of the small mine roadway were identified,drilling and in hole-forming imaging technology was verified,providing a basis for the later management of the goaf in the site.The detection results indicate that the comprehensive geophysical exploration method has a fast and efficient effect on the exploration of shallow small mine roadways,and has reference significance for solving similar geological hazard problems.
