Borehole Electromagnetic Method for Exploration of Coal Mining Goaf

Due to severe harms of goaf collapse, the goaf exploration and governance has become an urgent issue for protecting the normal life of local people. According to the coal mine geology, different geo-electrical model s have been employed for the purpose of discovering the goaf s . However, most existing methods require a large amount of computation consumption. In order to address this issue, a forward numerical simulation using the borehole electromagnetic method has been developed in this work to explore the coal mining goaf s . The innovation of this method is that the computation consuming can be saved significantly. N umerical simulation demonstrates high effectiveness of the borehole electromagnetic method in coal mining goaf exploration. Therefore, this research provide s a new idea for exploring the coal mine goaf s by geophysical method . DOI: http://dx.doi.org/10.5755/j01.eie.22.4.15913
