Mine voids in coal mines are usually encountered as resistivity lows because of the presence of acidic mine water. Other Methods, such as magnetics and ground penetrating radar have been used for detecting subsurface cavities, but can be subject to precision, interference, or depth limitations which restrict their use in mining applications.
The application of in seam seismic methods for coal seam exploration in connection with longwall mining is evaluated. The present exploration practice is reviewed. With the introduction of the relatively expensive high production longwall mining technique, in seam seismic methods are important to successful mining operations. The basics of relevant seismic methods are described, and a research ...

Mining operation. Mining engineers working in an established mine may work as an engineer for operations improvement, further mineral exploration, and operation capitalization by determining where in the mine to add equipment and personnel. The engineer may also work in supervision and management, or as an equipment and mineral salesperson.
Longwall mining technique has been widely used around the globe due to its safe mining process. However, mining operations are suspended when various problems arise like collapse of roof falls, cracks and fractures propagation in the roof and complexity in roof strata behaviors. To overcome these colossal problems, an underground real time microseismic monitoring technique has been .
