Currently, the development of technologies for exploitation of non-metallic mineral deposits in Ukraine is a guarantee of meeting the critical demand for large volumes of construction materials required to restore damaged and destroyed infrastructure as a result of Russian aggression.

The uniqueness of the proposed technologies is in the optimal combination of continuous, cyclic, and gravity-based mining and transportation equipment, integrated with mobile crushing and screening units. This approach enables deeper quarrying of construction raw materials by establishing a correlation between operational efficiency and the location of concentration levels. As a result, mining enterprise productivity has increased by 1.8 times, while development costs have been reduced by 45%. The developed environmentally safe technologies also reduce the need for the exploitation of new mineral deposits, contributing to land conservation during the post-war recovery of the country.

The implementation of digital modelling of excavation equipment while developing construction raw material deposits optimizes extraction processes. This improves the efficiency of rock mass transportation, reduces the required amount of mining and transportation equipment, and increases the production capacity of enterprises.

The results of this work have been successfully implemented in granite and refractory clay mining enterprises, yielding an economic benefit of UAH 32 million per year. The developed technological solutions can be adapted for use in other construction materials enterprises.
