Environmental Consequences of Open Pit Mining Blogger

Although many supporters of open pit mining play down this type of adverse effect, imagine the stress caused by living with nearly constant noise and vibration from mining activities. And if the mine is located in an area that was previously forested, the visual effects, meaning the loss of vegetation and the implementation of an industrial landscape, can be significant.

This thesis investigates the effects of equipment size selection on the economics of open pit mining. The work presented, illustrates the importance of considering equipment selection in the wider context of the entire mine. A methodology is presented for evaluating the various variables that are affected by equipment size, Equipment Size Sensitive Variables, (ESSV) that will aid the industry

How can metal mining impact the environment?

Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts. As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of waste rock are removed from the pits and deposited in

Environmental Risks of Mining

Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

1.1.3.1 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The

Iron ore Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO

OPEN PIT MINING THROUGH UNDERGROUND WORKINGS

OPEN PIT MINING THROUGH UNDERGROUND WORKINGS 1.0 INTRODUCTION A number of open pit mines in Western Australia (WA) are mining orebodies that have previously been mined by underground methods. There are hazards with high risk potential which develop where open pit mines approach and then progressively mine through underground workings.

Chapter 2: The Environmental Effects of Strip Mining The

Open Pit Mining. Open pit mining is similar to area mining. The technique is common in the western United States (and other parts of the world) where very thick — 50 to 100 foot — coal seams exist. Open pit mines are usually large operations. Production levels may exceed 10 million tons of coal per year.. The thick coal seams found at these large mines ensure that the amount of land
