- - - - • There are coal fields at Harnai, Degari, Sharig, and Mach.
      - • Bituminous is found in these fields.
      - • This type of coal is used in steel and brick kiln industries.
    - - • Coal fields are found in Sonda, Lakhra and Jhimper.
      - • Lignite is found in these fields.
      - • It is used for thermal power stations.
    - - • Coal can be found in Pidh and Dandot.
      - • Lignite and Bituminous are found there.
    - - • Coal is found in Marwal.
      - • Sub-bituminous is found there.
      - • It is used in the ceramic industry.
  - - - • This method is used when coal is underground.
      - • In this method, a vertical shaft is dug.
      - • Along the coal seams, several other shafts are along dug.
      - • To break coal seams, dynamite is used.
      - • Miners pick coal using a shovel.
      - • Once it is picked, trollies are used to transport the coal to the surface.
    - - • It used to extract coal that is on the hillside.
      - • For hillside coal extraction, horizontal shafts are dug.
      - • Multiple shafts can be dug at different levels.
      - • Dynamite is used to break the seams; shovel is used to pick up coal and trollies are used to transport the coal outside.
    - - • It is used when coal is visible on the surface.
      - • Dynamite is used to break these seams and shovel to pick them up.
      - • The coal is then supplied to industries using vehicles.
  - - - • Thar coal fields are rich in coal with 175 billion tons of coal (lignite).
      - • It is anticipated that this can produce almost 100,00 MW of power for the next 200 years.
      - • This coal can also be exported to other countries like India.
      - • Electricity will become cheaper.
      - • There will remain no need to import oil and billions of dollars will be saved.
    - - • Coal power sources can be damaging to the environment and will pollute rivers with waste and air with mercury.
      - • Mercury will contaminate the air and seafood and their continuous consumption can damage brain cells.
      - • The fly ash particles in the air can cause respiratory disorders in humans and animals.
      - • The fly ash particles in the air can also reduce crop yields.
- - - - • The pipeline provides a continuous and fast supply.
      - • It can transport a large amount of has.
      - • It is cheap after the construction of the pipeline.
      - • The pipes can leak gas.
      - • It can supply gas to only main cities like Karachi.
      - • The pipelines are expensive to build.
    - - • It is suitable for small users and can supply a small amount.
      - • It is portable.
      - • It is a slow transport.
      - • It provides a supply of gas that is interrupted when the cylinder is empty.
      - • It is expensive.
      - • There can be accidents.
- - - - • It offers a continuous supply.
      - • It allows you to transport a large amount of oil quickly.
      - • It is cheap once the pipeline construction is complete.
      - • But the pipelines can also leak oil.
      - • It can transport oil to main centers only.
      - • It can transport only one product.
      - • Its construction is expensive.
    - - • It can allow the oil to be transported to areas where there is no pipe construction.
      - • It can transport more than one product.
      - • It is best for small suppliers and users.
      - • It can transport only a small or limited amount of oil.
      - • It is a slow transport and can encounter accidents.
      - • It is expensive.
    - - • It can help the oil to transport to remote areas.
      - • It can transport more than one product.
      - • It is suitable for small users and suppliers.
      - • It can transport a limited amount of oil only.
      - • It is a slow transport, can encounter accidents, theft or leakage.
      - • It is heavy on the roads.
      - • It is expensive.
