QUESTION
Boulder in borewell

Dear team,

Recently, we had drilled a borewell at Madhanapalli area in Andhra Pradesh with 80 feet pvc casing. After drilling approximately 210 feet, there was a boulder and hevay flow of water came gushing out and drilling hammer did not rotate. We tried to drill further for 220 feet but we couldn't. Any one pls suggest, what to do now?
