Okay kiddo, let me explain mine closure planning to you in the simplest way possible.
Do you know what a mine is? It's a place where people dig deep into the ground to find valuable things like gold, silver, coal or diamonds. But when they take all the valuable things out, they need to close the mine.
Mine closure planning is like making a plan for when we need to close the mine. It's like a checklist of things that need to be done to make sure the mine is safe and the environment is protected.
Before closing the mine, people need to check the place carefully to make sure there are no dangerous things left behind. They need to take out all the equipment, clean the area, and fill up any holes or tunnels that were made. This prevents people or animals from falling in and getting hurt.
Once the mine is closed, people need to make sure that the environment is safe too. They might plant trees or grass to cover the area and protect it from erosion. They might also make sure that any groundwater or streams are not contaminated with chemicals or pollutants that were used in the mining process.
So, mine closure planning is basically a plan to make sure that after the mine is closed, everything is safe and protected. It's important to think about this so that the environment and people are not harmed.
