CATEGORIZATION OF UNDERGROUND WORKS AFTER METHAN

Abstract

By existing procedure of categorization, underground work in which there is no or low quantity of methan is being ranged to nonmethanic regime. Difficulties in defining the source of gas, especially when there is possibility of feeding from adjacent beds, compel observance of potential danger and the regime of work be declared as conditionally nonmethanic. The requests of so established determinations should be solved by corresponding projects (the paper is published in Croatian).
