Clearing site for landrigs

Does anyone know of any correlation between drilling (landrigs) in
limestone and suffering total losses whilst drilling the top hole
(26" hammer drilling) and the possibility of the losses being
exacerbated by the use of high powered explosives used when
constructing the pad?

It was said that a similar problem was encountered in Oman and when
the constructors of the wellsites reverted to a less powerful
explosive, the problems of total losses were reduced.

What are the industry opinions?
