Why is rehabilitation necessary in coal mining

There are objects so simple and ordinary that we forget their existence when we don't need them. Their presence is…. The age of coal starts towards the mid s, stimulated by the need for finding an alternative energy source to….

The melting of the ice cells, not only brings about the release of methane gas, but it also produces another…. In order to improve supply security, and therefore the diversification of sources to produce electric energy At the end of the fractional distillation, long hydrocarbon molecules can be transformed into lighter molecules by means of more…. In all electric plants, excluding photovoltaic solar plants, mechanic energy is transformed into electric energy through the same basic procedure Hydrogen is an energy carrier that allows to generate energy in an environmentally sustainable way The reactor that will be able to produce electronuclear energy without risk of explosion or radioactive waste Energy and environment.

We need to create more champions on the ground like Mr. Yulianto, who can provide the rehabilitation efforts with adequate technical capacity. Having worked on the rehabilitation of industrially degraded land as the head of the Center for Forestry Development Control CFDC in Sumatra, Banjar knew that a lack of technical capacity was one of the primary constraints for successful rehabilitation. He also knew the massive scale of the problem.

This can involve simply making the site safe and stable, but global best practice strives to create a landscape that can support future uses of the land — such as returning it to an agricultural landscape or identifying new beneficial uses.

At a practical level, coal mine rehabilitation typically involves flattening the steep sides of the mine, covering exposed coal with soil and clay and revegetating the area with trees and grasses. In the disused coal mine attached to Hazelwood Power Station near Morwell caught fire. The fire burned for 45 days, blanketing the surrounding area in toxic smoke and forcing evacuation of vulnerable residents. The evidence heard at the inquiry into the Hazelwood mine fire found that mine rehabilitation is the best way of preventing coal mines from catching on fire.

Only small areas are rehabilitated each year, leaving vast expanses of open-cut coal exposed, increasing the risk of fire and increasing the amount of coal dust being blown onto nearby communities. Mining is a process that is known to have a tremendous effect on both the land that the mine is contained within and the surrounding areas.

Two of the most common mining processes are those of underground mining and strip mining. Underground mining is known to cause a variety of things to take place, during the mining process. As a mining process, it consists of going deep into the ground, digging and tunneling through layers of dirt and soil, in order to reach deposits of coal, as well as various types of minerals, among other resources. Strip mining has a much more direct effect on the soil and vegetation of an environment. When you strip mine , you remove the soil and vegetation off of a piece of land, and then you are able to access deposits of coal, and other minerals, that are closer to the surface — thus causing a need for land rehabilitation after mining.

Both of these mining processes create various problems that affect the land that is housing these mines. Erosion is one of the most common problems that often takes place, and this is because removing the vegetation from one piece of land disrupts the soil. From this disruption, the soil is subject to heavy rain, storms, hurricanes, and other natural events, this creates further chaos within the surrounding area.
