Comparative Analysis of Resources and Production Volumes of Porphyry and Diabase

Abstract

Aggregates such as porphyry and diabase are widely used in road construction, railways and construction, which ensures their constant demand. The analysis of resources and the volume of porphyry and diabase extraction shows that the "Zalas" Porphyry Mine has significant resources of the raw material, which constitute as much as 25.4% of the national resources of this raw material, which makes the mine a significant enterprise on the market. In turn, the "Niedźwiedzia Góra" Diabase Mine constitutes less than 10% of the national resources, but these are the only industrial resources of this raw material in Poland, which ensures its high market value. Analyses have shown stabilization of porphyry extraction in recent years, while diabase resources have decreased, which emphasizes the need for long-term planning and exploration of new deposits.
