As the photovoltaic (PV) industry continues to evolve, advancements in Coal mine explosion-proof energy storage have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.
But if some explosion-proof technologies are not used in a timely manner, a minor fire accident may evolve into a major coal mine explosion, with unimaginable consequences [3, 4]. Therefore, it''s necessary to conduct more research on the ignition process and explosion propagation of coal dust clouds in confined spaces, which has a distinct

This article addresses the issue of energy waste resulting from frequent braking of underground mine cars and proposes an optimization design to address this. The proposed solution involves the installation of a regenerative braking device within the mine cars to capture and reuse the energy wasted during braking. This implementation improves the endurance
Introduction Coal is one fundamental energy source for human. However, coal mining is full of dangers. In the procedure of coal exploiting, lots of flammable gases, such as CH 4, CO, etc, and coal dust are produced, which are easily ignited. Explosion-proof design Coal mine is a typical explosive gas atmosphere, in which explosive gases
