Abstract
In 1988 more than 25.5 million meters of wells were drilled for solid minerals in our country. Obviously, this was the maximum for all the years of existence of the geological industry, and it is unlikely that such a volume of drilling will be achieved in the future. However, during the period 1968-1990 the volume of geological exploration drilling decreased by almost 3 million meters. What are the main reasons for the decline in drilling?
