In the beginning the whole mining portfolio, we have actually noticed that all that is needed from us is to identify the problem/s that causes the environment to be disrupted by the whole mining situation we need to understand what we are looking for, for instance, we can never understand why these mines are causing problems if we don’t know what mines are, we can never understand the continuation of mines and why they harm the environment if we do not know why or how mines do what they do.
Firstly let us understand the following definitions:
Mine- An excavation in the earth for excavating coal or other minerals.
Environment- The surrounding or conditions in which a person operates.
Mineral Resources- Natural resources in the form of mineral
We have identified a problem that is only found at coal mining , is the smoke that is produced when burning coal as a result of it polluting the Atmosphere , Ozone layer, Water(killing the Marine life)also the vegetation.
According to research it was said that the gases released after burning coal are nitrogen, ammonia, carbon monoxide and methane. Scientists know that …
NITROGEN- is a non-metallic element found in group 15 on the periodic table .It has an atomic number of 7,meaning it has 7 protons and it has an atomic mass of 14.007(atomic mass unit ).Nitrogen is usually found in a gaseous state and makes up 78% of atmosphere .
AMMONIA-it is a colourless, pungent gas, NH, extensively used to manufacture fertilizers and a wide variety of nitrogen-containing organic and inorganic chemicals.
CARBON MONOXIDE-colourless, odourless, highly poisonous gas, formed by the incomplete combusting of carbon or a carbonaceous material, such as gasoline.
METHANE-odourless, flammable gas, the major constituent of natural gas that is used as a fuel and is an important source of hydrogen and a wide variety of organic compounds. It is also proven that when they are combined together, they are very poisonous.
Coal combustion releases mercury, particulate matter, nitrogen oxides, sulfur dioxide, and dozens of other substances known to be hazardous to human health. This report looks at the cumulative harm inflicted by those pollutants on three major body organ systems: the respiratory system, the cardiovascular system, and the nervous system. The report also considers coal's contribution to global warming, and the health implications of global warming.
Viewed in this way, the totality of coal's impact on health becomes clear. Coal pollutants affect all major body organ system. heart disease, cancer, stroke, and chronic lower respiratory diseases.
Respiratory Effects: Air pollutants produced by coal combustion act on the respiratory system, contributing to serious health effects including asthma, lung disease and lung cancer, and adversely affect normal lung development in children.
Cardiovascular Effects: Pollutants produced by coal combustion lead to cardiovascular disease, such as arterial occlusion (artery blockages, leading to heart attacks) and infarct formation (tissue death due to oxygen deprivation, leading to permanent heart damage), as well as cardiac arrhythmias and congestive heart failure. Exposure to chronic air pollution over many years increases cardiovascular mortality.
Nervous System Effects: Studies show a correlation between coal-related air pollutants and stroke. Coal pollutants also act on the nervous system to cause loss of intellectual capacity, primarily through mercury.
Global Warming: Even people who do not develop illnesses from coal pollutants will find their health and wellbeing impacted due to coal's contribution to global warming. The discharge of carbon dioxide into the atmosphere associated with burning coal is a major contributor to global warming and its adverse effects on health and wellbeing worldwide, such as heat stroke, malaria, declining food production, scarce water supplies, social conflict and starvation.
MATERIAL USED FOR THE MODEL
4 different Tins
Electric Jig Saw
Measure the planks using the given measurements by using the electric jig saw.
Join the planks using the nail.
Cut 2 tins in half, and join the 3 tins of underground demonstration with a Silicon.
Make a paper Mache by using the crushed papers and flour on the tin that will be placed on the surface of the frame structure.
Make an electric circuit for the motor that will be placed inside the tin that is on top of the frame structure.
Place the motor inside the tin that is on the surface.
Make a fire place inside the 3 tins that is underground demonstration, and burn the cow to make the smoke.
Join the PVC pipe aside the middle tin that is in the frame structure, so that the smoke can flow inside. And transfer the smoke towards the Turbine.
Join the PVC pipes to build-up the Turbine.
Make an electric circuit for the motor that will be placed on top of the Turbine.
Place the motor on the top of builded Turbine.
Paint the frame structure.
Paint the tins that are placed inside the frame structure.
Cover one side of the frame structure with the plastic cover, so that it can be easy to see through.
Pin up the plastic cover on the front side of the frame structure.

In summary, our society and environment would be much healthier if we all started to come up with solutions rather than excuses that would be more helpful towards building more considerate plans so that we can not only help mineworkers but also assist the environment that is in harm followed by the communities around them. Giving us a better outcome towards the future of our mineworkers and the environment. Thank you.
