Technologies in Exploration, Mining, and Processing INTRODUCTION The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use.
The company president looked at me and thought about it for a minute. Two years later, when I encountered them again on another coal property, they were logging through the rods! They had re-designed their geophysical tools to log through the rods, tested them …

Furthermore, the distinctions between near-surface geophysics, environmental geophysics and coal mining geophysics are being lost. For example, microseismic monitoring is now used in applications right across rock engineering — from hard rock mining, to coal mining, to petroleum recovery.
Exploration geophysics is an applied branch of geophysics, which uses physical methods, such as seismic, gravitational, magnetic, electrical and electromagnetic at the surface of the Earth to measure the physical properties of the subsurface, along with the anomalies in those properties.
Coal is burned largely to produce electricity and is a major contributor to air pollution with coal power plants emitting carbon dioxides and nitrous oxides. Another major resource used for energy is oil.
