Open Pit Mine Essay

856 Words4 Pages

To supply minerals and materials to the colony an open pit mine will be created. The quantity and value of minerals were used to determine the size of the pit and the equipment needed. This model will reflect the model of an example open pit mine in Chile called the “Escondida Mine”. The quantity of minerals needed was decided upon with the goal to make housing for the community in mind. Based on the minerals needed, processing plans were also determined.
Using the chart displayed to the right, specifically the Pathfinder data, possible minerals to mine were chosen. The mine will be used to extract mainly SiO_2,Al_2 O_3,Fe_2 O_3 and MnO_3. The silicon produced will be used in the production of solar panels along with windows and insulation for the housing. Aluminum will be used for walls and wiring in the housing. Processed iron can be used for pipes, nails, and heating. Lastly, Magnesium will be mined mainly for the use …show more content…

Assuming 2 drills will be required, an equation to determine the diameter of the drill can be represented by t=170d^2 [4]; where (t) is the tons of ore drilled per day and (d) is the diameter of the drill. Another major piece of equipment needed are haulage trucks. The number of trucks required can be determined using the equation N_t=0.25((T_p^0.8)/t) [4]; where (N_t) is the number of trucks, (T_p) is the tonnage of daily ore and (t) is the tonnage of the truck, which is estimated to be 189 tons. The next piece of key equipment are shovels. To determine how many shovels are required for the pit, the equation N_s=0.011 (T_p^0.8)/S [4] can be used where (N_s) is number of shovels and (S) is size of shovel in cubic yards. To first determine the size of the shovel required the equation S=0.145T_p^0.4 [4] can be used. The model output indicates 2 drills with the diameters 10.9 inches, 4 trucks, and 4 shovels, 15.95 cubic yards large are necessary to sustain this

    The rock cycle is extremely helpful and useful for scientists all over the world. These scientists use physical geology, which carefully focuses on how rocks form into other rocks (Doc. 2). Also, through the rock cycle, three types of rocks form, which are called igneous rock, sedimentary rock, and metamorphic rock (Doc. 1). The rock cycle is much like the water cycle, but it takes millions of years for a rock to form, wear down, and form again.

    Coalmining was a prominent industry throughout eastern Pennsylvania, northern Maryland, and Wyoming. In 1885, legislation was passed in order to restrict the working age of miners. Breaker boys, who worked aboveground to sort slate, rocks, and other debris from the coal, were required to be at least twelve years of age. Underground miners were required to be at least fourteen years of age. Boys ' parents often presented a fake birth certificate with an altered date of birth in order to have their children, who were often as young as five or six years of age, work in the mines.

    Examine Your Response: Synthesis With ethics providing the base framework for the way we conduct ourselves on every level from individually to globally, it’s important to study them for a host of reasons. First and foremost, it allows us to analyze our behaviors and determine what criteria is valuable in our decision making processes. Studying ethics gives us different outlooks and perspectives on problems we may not consider when looking at it from our individually engrained default approach. It also allows us to look for shifts and changes in mindsets, attitudes, and values, so we can see how we’re progressing as a society. We’re also given the opportunity to compare and contrast our personal governing philosophies with those of others around us to see where we fit in with our society and measure how well we’re meeting the standards we set for ourselves.

    The hollow earth theory or ‘hohlwelttheorie’ as it is called in German, is the idea that the Earth is not a solid mass but rather an entirely hollow sphere that within contains a substantial interior space. The idea goes back to ancient mythology, folklore, and legends of a subterranean land inside the Earth, from which places of origin and afterlife were thought to be located, such as the Christian hell described by Dante, the Greek underworld, the Hindu ‘Patala’, the Celtic ‘Cruachan’ just to name few, which in its majority were caves or holes that connected the outside Earth with its interior, from which strange creatures would emerge and be seen in the surface.
