What are the positive and negative impacts of mining?

Some positive impacts of mining are that it brings employment to the area and community development projects. Negative impacts include changing the social dynamics of the community, impacting health and livelihoods, and preventing access to clean land and water.

What is the average life of a mine?

If you're referring to land mines, they can lay in the ground and remain dangerous for many decades. Unexploded ordnance of various types often lasts for a very long time. Even today, live, unexploded bombs from WWII are sometimes dug up at construction sites in Britain.

What is positive about Rio Tinto?

As there website homepage declares: "Helping to create and maintain the diversity of natural life is a responsibility that we take very seriously. We operate in regions throughout the world that are recognised and valued, both locally and globally, for their biodiversity and we are committed to managing them by reducing our impacts and capitalising on conservation opportunities. There is now increasing expectation that industry should take a role in conservation management. Our biodiversity programmes enable us to better understand and address identified issues through a sustainable development approach, involving traditional landowners and local communities, governments and local non government organisations (NGOs). Our strategy states that we aim to have a net positive impact (NPI) on biodiversity. We, therefore, need to demonstrate that our actions have positive effects that outweigh the inevitable negative effects of the physical disturbances and changes of land associated with mining. "

What is the history of coal mining?

oal is formed when peat is altered physically and chemically. This process is called "coalification." During coalification, peat undergoes several changes as a result of bacterial decay, compaction, heat and time. Peat deposits are quite varied and contain everything from pristine plant parts (roots, bark, spores, etc.) to decayed plants, decay products and even charcoal if the peat caught fire during accumulation. Peat deposits typically form in a waterlogged environment where plant debris accumulated; peat bogs and peat swamps are examples. In such an environment, the accumulation of plant debris exceeds the rate of bacterial decay of the debris. The bacterial decay rate is reduced because the available oxygen in organic-rich water is completely used up by the decaying process. Anaerobic (without oxygen) decay is much slower than aerobic decay. For the peat to become coal, it must be buried by sediment. Burial compacts the peat and, consequently, much water is squeezed out during the first stages of burial. Continued burial and the addition of heat and time cause the complex hydrocarbon compounds in the peat to break down and alter in a variety of ways. The gaseous alteration products (methane is one) are typically expelled from the deposit, and the deposit becomes more and more carbon-rich as the other elements disperse. The stages of this trend proceed from plant debris through peat, lignite, sub-bituminous coal, bituminous coal, anthracite coal to graphite (a pure carbon mineral). Because of the amount of squeezing and water loss that accompanies the compaction of peat after burial, it is estimated that it took 10 vertical feet of original peat material to produce 1 vertical foot of bituminous coal in eastern and western Kentucky. The peat-to-coal ratio is variable and dependent on the original type of peat the coal came from and the rank of the coal.

What former governor was murdered during a mining dispute?

Former Governor William Goebel of Kentucky was assassinated during a political and mining dispute in 1900. He was shot on January 30, shortly after being inaugurated, amid tensions surrounding a contested election and labor conflicts in the coal industry. Goebel succumbed to his injuries on February 3, making his assassination a notable event in Kentucky's turbulent political history.
