Coal is a lowcost commodity and coal miners profit margins are slim, such that mining companies must maintain tight cost control to achieve acceptable returns. The challenge to coal geophysics is to adapt to these economic constraints and provide costeffective, reliable methods for exploration and mining .
constitute coal exploration, mining, off highway hauling, processing, maintenance and reclamation: 1) Coal is produced in a surface mining operation that begins with locating the coal deposit to be mined, clearing of surface obstacles and overburden from the land above the coal deposit to be mined, continues with the removal of waste material

coal seam and leaving behind ''pillars'' of coal to support the roof of the mine. These pillars can be up to 40% of the total coal in the seam – although this coal can sometimes be recovered at a later stage. This can be achieved in what is known as ''retreat mining'', where coal is mined from the pillars as workers retreat. The roof is
RIM instruments send radio waves through the rock/coal, reacting to geologic layering, composition, structure and void‐space. Applicable to most geological or geotechnical imaging applications include coal mining, hardrock and metalifferous mining, environmental remediation, and civil engineering.

Aug 18, 2015· Mining operations are complex. They aren''t your runofthemill type projects. These billion dollar complexes consist of various interconnected projects, operating simultaneously to deliver refined commodities like gold, silver, coal and iron ore. It''s a five stage process and we''ve broken it down using GIFs. Exploration
Highresolution 3D surface seismic method and former coal geophysics program of a US coal company Lawrence M. Gochioco, GX Technology Corporation, Houston, Texas Introduction One of the best kept technology secrets in US coal mining history was that there was once a robust coal geophysics program that was fully utilized by a local
According to Statistics Canada, compensation is highest in coal mining, at 1, per week, and lowest in nonmetallic mineral mining and quarrying activities, at per week. Workers in oil and gas earn a 76,930 average annual base salary, while employees in coal mining earn 70,886 and workers in metal ore mining earn 59,273.

Due to the influence of mining technology, some coal mines will leave minedout areas (or goafs) in the rock mass after mining. If the distribution law and influence scope of minedout areas cannot be accurately explored and controlled, it will bring great potential safety hazards to subsequent coal mining and cause serious harm to adjacent houses, roads, bridges, railways, and so on.
