Uneven land surfaces created by limestone mining can cause transportation problems in the location. Which of these is the best plan to solve this problem?
water the mining area regularly
reduce the use of heavy machinery in the mining area
choose other uninhabited locations for limestone mining
make reclamation mandatory after limestone has been removed
this one just makes the most sense. If you mess with line stone to much or you are using to much heat around lime stone it will go boom. So the correct answer is #3.
