A seawall construction at Mt. Gibson has opened debate whether to re-open the Koolan Island pit mines by way of mine dewatering flooded areas. Although the process of mine dewatering has been approved, environmentalists claim it will make the area and soil unstable, while mine workers claim it will be a great new start for more jobs and better industry.
Although both parties may have a point, the following list breaks down the pros and cons of strip mining a sunken mine through mine dewatering in Australia.
Strip mining, unlike underground mining, recovers more raw materials in a spread area than tunneling for elements. It is a quick and fast procedure that can be started as soon as Australia mine dewatering services drain a pre-planned area. Strip mining also ensures that funding from the government is utilized well by the mining company while making profits as well. It is an economical answer rather than having to rent, fly over or build equipment that can cut or tunnel through rock. With Australia’s terrain being hard on top and softer, almost clay like limestone beneath, cutting through granite will require machinery probably sent over from China or having to wait for months for it to be built in the homeland.
Strip mining also requires less effort when retrieving raw materials. As a mining company, they have to retrieve raw materials and transport them to the surface to be polished or distributed to other factories. This is done more efficiently with strip mining. Since the method of strip mining is only scratching the surface of the Earth, it is the least costly way to mine for raw materials. If you consider it carefully, strip mining is also safer for the miners involved. There are no accidental blockades or deaths underground. Also, once a mining company is done with an area, they are legally required to cover the land with topsoil in order for plants to be able to grow again, while safeguarding the area from landslides and tectonic plate related earthquakes.
Strip mining is still a very volatile and controversial topic of debate amongst environmentalists and researchers. Although the method is efficient, it could be hazardous to human health. Not only does it change the topography of the area, the reclaimed land has been known to cause cancer amongst workers or people who unknowingly buy land in the area. This is because of chemicals that may seep into the water system and not harm vegetation, but harm humans and other living animals in the area. Since mining explosives are used for strip mining, there is also a threat of human error and accidents while debris, silica, and radiation may cause miners to get cancer later.
Even with correct topsoil covering and mine dewatering procedures, environmentalists insist strip mining causes permanent loss of native vegetation, ecosystems, and hardens the underground water forever. They also are against the erosion of the soil which researchers have proven worsens flooding in the area.
Like all things, strip mining may need to be perfected to suit the health and environmental necessities before more mining companies undertake the practice.
