How made to GI earth-pit with salt and coal?

1. Materials needed: (1.25 m) copper road , salt and coal . 2. How to make to GI earth pit : a. Dig a hall in the dirt ground at least for 1m depth. b. Install a PVC pipe of 1m length and 10 cm width inside this pit. c. Install the copper road in the middle of the PVC pipe and start to make layers of 10 cm in sequence of salt once and coal till the PVC pipe is filled you must keep the road tip over the ground at least for 10 cm so you could get connection to your ground system. d. When you get done of the mix layers of the salt and coal.. you need to take the PVC pipe off to get contact between the system and the ground. e. You could joint the end tip of the copper road to the facility earth system. And then you will get a good earthing system .. for large facilities with high load consuming power you could make 3 pits the same way with 3 copper roads joint them as triangle by a copper cable and use any one of the 3 points as earth main point for the system .. Hope I could Help somebody with this .. Electric Eng. Hussein K. Hasson Baghdad , Iraq


Which type of map would you use to find the location of a layer of coal at Earth's surface and why?

You would use a geological map, which displays the types and ages of rocks on the Earth's surface. This map would help you locate the layer of coal as it shows the distribution of different rock types, including coal-bearing formations, allowing you to identify the specific location of the coal layer.


Which of the following strategies can help Earth's coal supply last longer?

Implementing carbon capture and storage technology to reduce emissions, increasing energy efficiency in coal-fired power plants, and promoting renewable energy sources as alternative to coal can help extend Earth's coal supply. Additionally, investing in research and development to find cleaner and more sustainable ways to use coal can also contribute to making the supply last longer.


How do people dig up coal?

Coal mining involves using specialized machines and equipment to extract coal deposits from under the Earth's surface. Miners use drills, explosives, and other tools to access coal seams, which are then cut and removed using large machinery. The extracted coal is then transported to the surface for processing and distribution.


What is the method used to extract shallow deposits of coal from the earth?

The method used to extract shallow deposits of coal from the earth is surface mining, specifically using methods like strip mining and open-pit mining. These methods involve removing the overlying vegetation, soil, and rock to access the coal seams underneath, making it easier and more cost-effective to extract the coal.

Do you buy power from coal mines?

The coal mines dig up the coal from under the earth. The coal is then sold to whoever wants it. Some industries use coal for power. Coal-fired power stations are a huge buyer of coal. They burn the coal to heat water and use the steam to turn turbines which produce electricity. This electricity is then passed on to Energy Companies who sell the power to us.
