A new underground Lead-Zinc-Silver mine is planned to start at a depth of 1200 m below the surface level with an annual ore production of 2 million tons. After performing insitu testing, it was found that the proposed mine site is having very high horizontal stresses compared to the vertical stresses. Based on the given situation, what stability and ground control challenges will be there in your opinion and how you will manage them in a most effective manner without compromising with the safety and stability
