What are the advantages of mine monorail locomotives with drive wheel polymeric rims?
The potential use of mine monorail tracks are conditioned by the following factors: low payload ratio of the train; reduction of the mine workings cross-section area due to transfer of
auxiliary transport to the upper part of the workings; high operational safety; as well as the possibility of dismantling the track in the unused sections and subsequently installing it in new mine workings. The use of rubberized rollers in the drives of mine monorail locomotives enables the coefficient of adhesion of the wheel with the monorail to be increased. The researchers established that an increase in the carriage mass from 20 to 47 kN leads to 32 % less durability of a monorail locomotive drive wheel rim (from 8700 to 5900 hours).

We present the articles of the first issue of scientific journal "Mining Science and Technology” (Russia) for 2025:
Scientists investigated a novel method for reinforcing sandy soils using polyurethane compounds. During construction of engineering structures and mineral deposit development, strengthening loose rock formations often becomes necessary, yet conventional polymer reinforcement techniques provide insufficient strength. Experimental studies introduced a two-solution treatment technology: initial mixing of sand with a slow-reacting highly elastic compound followed by addition of 5% rapid-curing single-component resin. Triaxial compression tests demonstrated that this approach creates cured polymer aggregates that bind mineral grains without complete void filling, increasing sand strength by 5-fold. The resulting geomaterial exhibits superior deformation resistance under axial stress, while maintaining strength independence from rapid-curing additives when the resin-to-rock volume ratio exceeds 0.3. The research confirms that the dual-solution method significantly enhances soil stability even with minimal polymer consumption, offering important practical applications for construction and mining operations.
