TCO A: What process would you use for identifying project risks for a second Oresund Bridge project? What risks would you raise for each alternative? Taking into consideration that this is the 2nd attempt at the project‚ I would begin by creating a checklist based off historical information from the risk knowledge base in the first project as well as other bridge projects. I would then use brainstorming or even interviewing others and perform a SWOT analysis. I would then classify the risks

iron oxides. They develop by intensive and long-lasting weathering of the underlying parent rock. Tropical weathering (laterization) is a prolonged process of chemical weathering which produces a wide variety in the thickness‚ grade‚ chemistry and ore mineralogy of the resulting soils. The majority of the land areas with laterites was or is between the tropics of Cancer and Capricorn. Historically‚ laterite was cut into brick-like shapes and used in monument building. After 1000 CE construction

that South Africa has become the third largest iron ore supplier for China through the competition with India‚ which will have a great influence on China’s mining machinery industry. According to Business Day Live’s report‚ the iron ore export to China from South Africa was 40.6 million tonnes in 2012‚ while Indian exports plunged nearly 55% to 33 million tonnes. It is evidently that South Africa managed to increase of its share of iron ore sales to China in the unstable economical situation.

copper in China mainly are towanite‚ chalcocite‚ bornite‚ malachite and etc. According to the technical conditions of smelting‚ the copper ore can be divided into three classes based on the proportion of copper oxide and copper sulphide‚ that is‚ sulfide ore‚ which contains less than 10% copper oxide；oxidized ore‚ which contains more than 30% copper oxide; mixed ore‚ which contains 10%~30% copper oxide. Copper is one of earliest metals that be found and used by human beings‚ it is aubergine‚ with the

Copper ore is first quarried from the copper mountain and the raw materials are got. Next is to process and mine the raw copper materials. They are sent into jaw crusher for primary crushing through vibrating feeder. After the raw materials are crushed into coarse ones‚ with belt conveyor‚ they enter into impact crusher or cone crusher for the secondary crushing. There are two different copper ores‚ the oxide ore and the sulfide ore. The oxide ores are commonly leached‚ while the sulfide ores are beneficiated

ground surface will cave in to the underground as well. Scoop trams or Load Haul Dump (LHD) vehicles transport the muck‚ loosened rocks‚ to an ore pass where the rocks are lifted to the surface. Drilling and blasting takes place at different underground levels of the mine at the same time. As the blasted rock‚ muck‚ is continuously transported to the ore pass‚ more blasting will encourage the roof to cave in to the void and further into the drift. This is repeated until blasting‚ caving and transporting
