Dewatering methods for underground mines can range from the relatively simple collection of water seeping into the mine from fractures or roof bolts, to more complex drilling of dewatering wells from the ground surface, drilling of drainage boreholes from within the mine, or mining of drainage galleries.
How Underground Mining Works. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers ]. Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper uranium mines can reach 6,500 feet,...
Overview. Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves largescale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water.
May 14, 2018· Benefits of Fiber Optics for Underground Mine Communications. Furthermore, since optical fibers are composed of glass, they are immune to induced currents, cross talk and EMI generated by large AC motors and other electrical equipment used in mining operations. Fiber optic cables and connectors are designed and qualified for use in mines by...
Underground mining however requires significantly more power as compared to surface mining. In the face of high cost of mining inputs and inadequate supply of power, surface mining therefore becomes the favourable, cost effective and preferred option. • Safety considerations compared to underground mining There is also low numbers
Strip Mining Cons to Consider. To access some of the needed products in the ground, solvents and other chemicals are sometimes used to gather the needed items. These can then enter into the groundwater, leak into the environment, and pollute the surrounding atmosphere. 3. It takes a toll on the environment.
Cave mining methods will be the underground method of choice in the future. It is only relatively recent that this mass mining method, despite 70 years of use, has begun proving its potential. That interest is being fueled by the depletion of near surface ore bodies suitable for open pit operations.

proper roles of both sides. Mining development would benefit from the creation of space in the public discourse where stakeholders' interests can be reconciled. This report evaluates the relative benefits and costs of mining in Central America, as well as the distribution of benefits and costs among the stakeholders. We will
Practical Advantages and Disadvantages of an Underground House. Now, let us check out the pros and cons of an underground house in some detail. ► They provide a safe refuge from extreme weather such as tornadoes, hurricanes, high winds, and hailstorms. ► The earth surrounding the homes provides natural soundproofing,...
Chapter 1: Mine Ventilation – An Overview Page 1 Min218 Reading Material A BRIEF HISTORY OF MINE VENTILATION by McPherson (Excerpts of Chapter from "Subsurface Ventilation and Environmental Engineering, "1993) Observations of the movements of air in underground passages have a long and fascinating history.
The result is an industrial environment that can run productively, predictably, and with lower risks. In an underground mine this has the potential to bring forth huge improvements in safety and productivity, but a new and unique communication solution is needed and mine operators need to get clued up.
Underground coal mining is the most important source of fugitive methane emissions, and nearly 70% of this methane is emitted through mine ventilation air at low concentrations. Thus, CMM is an important issue from an environmental point of view. Further, capturing .
