A metallic ore deposit of massive shape is given. The ore is reasonably strong to support itself. The rock above the ore is weak and cavable, and it can break into medium size pieces when unsupported. The ore grade is low and the ore grade distribution is consistent. A high-scale production rate is required. What kind of underground mining methods can be applied to extract this mineral deposit? Explain, in details, the type of mining method that you found for this ore deposit, provide illustrations.

Bearcreek Mines paid $433,000 for the right to extract ore from a 450,000-ton mineral deposit. In addition to the purchase price, Bearcreek Mines paid a $155 filing fee to the county recorder, a $2,800 license fee to the state of Utah, and $95,045 for a geologic survey. Because the company purchased the rights to the minerals only, it expects this mineral rights asset to have a residual value of zero when it is fully depleted. During the first year of...

Montana Mining Co. pays $4,272,720 for an ore deposit containing 1,485,000 tons. The company installs machinery in the mine costing $206,200, which will be abandoned when the ore is completely mined. Montana mines and sells 142,000 tons of ore during the year. Prepare the year-end entries to record both the ore deposit depletion and the mining machinery depreciation. Mining machinery depreciation should be in proportion to the mine’s depletion. (Do not round intermediate calculations. Round your final answers to the...

It is desired to use a 12-in.W-shape for a column to support a beam. Select a trial size for the column for the following data: column factored axial load from above is 485 kips, factored beam reaction is 100 kips, and unbraced column height is 18ft. * Check the section found to see if it complies with the AISC interaction equations for axial compression plus bending.* (Interaction Formula Check)

4) Suppose a product can be produced using virgin ore at a marginal cost given by MC1 = 0.5q1 and with recycled materials at a marginal cost of MC2 = 5 + 0.1q2. a. If the inverse demand curve were given by P = 10 ? 0.5(q1 + q2), how many units of the product would be produced with virgin ore and how many with recycled units? b. How would this change if the inverse demand function were P =...
