  2. Mining 1.What do we Mine? 2.Open Pit Mining 3.Underground (Shaft) Mining 4.Issues Facing Mining in Canada 5.Improving Canada’s Mining Industry

  3. What Do we Mine in Canada? What: Potash Where: Sask. For: Salt, Fertilizer What: Copper Where: Ontario For: Pipes What: Zinc Where: New Br. For: Brass

  4. What Do We Mine in Canada? What: Diamonds Where: NWT For: “bling” & industrial cutters What: Gold Where: NWT For: “bling” What: Coal Where:Maritime For: Fuel

  5. What do we mine in Canada? Source: http://www.planete-energies.com/Frontoffice/Players/PopupPlayerImage.aspx?directory=img_2_4_2_extract02&pageFrom=encyclo Oil pumped from under the ocean…….. Hibernia Drilling Rig platform off the coast of NFL oil

  6. Off Shore Oil Rigs

  7. What do we mine in Canada? Oil pumped from the land… Oil derrick on land, oil rig on the sea….

  8. Open Pit Mining This method is used when the deposit is close enough to the surface for mass removal of ore to be economically viable. Its simply a big hole in the ground where the mineral is removed

  9. Open Pit Mining

  10. Open Pit Mining Impacts • Destruction of Vegetation • Large volume of unused waste-rock must be stored. • Disruption of ground water • Production of dust and radon gas during blasting.

  11. Open Pit Mining A simple layered open pit mine.

  12. Open Pit Mining A digging wheel at work. Coal is can be mined this way as well as oil sands.

  13. Open Pit Mining A digging wheel close-up. Bigger size = greater efficiency, right?! big bucket

  14. Mining Truck big truck

  15. Open Pit Mining

  16. Mining Equiptment

  17. Underground (Shaft) Mining

  18. Underground Mining: -Mining that is done completely underground. -Tunnels (shafts) are blasted deep into the earth to reach minerals. -This type of mining is much more dangerous due to cave-ins. - Coal, salt, silver, diamonds, gold….

  19. Underground (Shaft) Mining Wire mesh to prevent loose rocks from falling.

  20. Underground (Shaft) Mining Temporary support beams

  21. Underground (Shaft) Mining A scooptram at work.

  22. Underground Mining Impacts • Destruction of Vegetation. • Disrupts the water table • Needs to be excavated before mining. • Danger of collapse • Dust and noise

  24. Issues Facing the Mining Industry • Negative Impact on the Environment • Abandoned Mines • Loss of Jobs • Echo Effect • Exhausting the Supply • Staying Competitive • Boom-Bust Towns

  25. Acid Rain: Kills Forests

  26. Abandoned Mines: Leave scars on the Earth’s surface and can be dangerous

  27. Exhausting the Supply: When mines run out , So do the jobs!

  28. Mining Centres in Canada
