Some effects of mining on the environment and how to solve it

The effects:

1.It destroys forest and wetlands.

2.It may mean that you have to cut down lots of trees just to get to the spot that has all the gold or iron ore.

3.Many mine require tailings dams to prevent waste being washed into the rivers. Unethical miners can dispense with the dams, to save costs, resulting in massive pollution downstream. In other cases, the tailings dam can overflow, and even breach, during periods of heavy rain.

4.Underground coal mining can require the removal of almost an entire layer of material deep under the surface. When the timber supports collapse, this can lead to subsidence. The subsidence can mean economic loss to people above or damage to natural areas. It can even cause cracks in river beds, leading to loss of river flow.

5.Some mining involves the inadvertent dispersal of heavy metals, such as lead, into the atmosphere. This can have serious health effects, including mental retardation in children.

6.Asbestos mining causes the dispersal of asbestos into the environment. This will cause deaths among local residents and workers, often several decades later. Fortunately, the mining and use of asbestos are banned in most parts of the world.The design of the sand stone crushing technological process should use the dry production process which relatively have little influence on the environment at the premise of meeting the concrete aggregate technical requirements. Using wet production process must take reasonable wastewater treatment process for the comprehensive utilization of waste water, waste residue, waste to treasure, and minimize the waste disposal to meet demands of environmental protection.

In the process of mining, processing, it is easy to bring damage and harm to the environment and human life environmental, which include the damage on vegetation and slope body stability caused by material mining, the dust and noise generating in the process of crushing and screening, which have very seriously impact on the air quality and human survival environment. What”s more, the waste water and waste residue generating in washing the screening machine enter the river valley, land, which will impact the environment a lot.

Especially, in the crushing and screening process of the aggregate, in order to ensure the quality of finished aggregate and reduce the processing cost, generally according to the processing characteristics of raw materials and the different scale, processing technology include two kinds of craft union: full dry production and full wet production. It will generate large amounts of dust and noise in the sand stone materials” crushing process, screening machine driven by the motor vibration exciter to make the material on the screen surface for a straight line or circular motion, the mechanical movement of the material and the screening machine will produce noise as well. Dry screening will produce a large number of dust, while as with the wet screening, a large number of sewage need to deal with.

Sand and gravel processing equipments are mostly strong noise and dust source, when pollute the surrounding environment which will threat the staff”s health. So we should consider in advance when selecting the equipment and technical design.

There is no reason for a blanket ban on mining. However, the environmental impact of each proposed mine should be analyzed before permission to proceed is granted. Mining operators must be aware of the potential impacts of their operations and ensure minimum risk to the environment.The holes also spread a big germ to many parts of the world which soon gets the world polluted.

As the professional manufacturer of complete sets of mining machinery, such as Rock crusher,Impact crusher, Rock crusher, Henan Hongxing is always doing the best in products and service.
