Borewell failure at 45 feet in Rourkela, Orissa : Alternate drilling techniques sought

I had undertaken the drilling of a borewell at my house located near the river bank ‘Bramhani’-village in Bonai Sub-Division, 40-50 Kms from Rourkela, Orissa.The operator could not dig after 45 feet as the conditions were of wet soil with small and medium stones. The diameter of the failed borewell is six inches. Surrounding places have functional borewells.

 The operator was suggesting to call for another digging machine having rotary facility (rotary compressor) for drilling.Kindly suggest a suitable solution to this problem.
