Borewell 150 ft in Bangalore, Karnataka, found boulders & stopped drilling - Should the blouder be crushed or stop drilling

Dear All,

We drilled a borewell about a year and half back upto a depth of 150 ft and had to stop as we encountered boulders in Bangalore. Now the bore is completely dry.

We were informed by the person who checks the water source that there is water available beyond the boulders.

Would like to know if the blouders can be crushed and dug further to find the water source or I should not proceed further.

Thanks,

Karthik
