Today, coal mine tools have evolved into highly sophisticated equipment that incorporates modern technologies such as automation and remote control. Continuous miners, for instance, are capable of cutting coal, loading it onto conveyors, and propping up roof supports automatically, all while being operated from a safe distance. This not only maximizes coal production but also ensures the safety of mining personnel by minimizing their exposure to hazardous environments.

Coal drill bits come in various types, each tailored to specific geological conditions and drilling needs. The most common types include button bits, tungsten carbide insert (TCI) bits, and steel-to-steel (STT) bits. Button bits, with their carbide buttons on the surface, are ideal for softer rocks and coal seams due to their excellent wear resistance. TCI bits, on the other hand, are more suitable for harder formations due to their tungsten carbide inserts that provide exceptional toughness and wear resistance. STT bits, made entirely of steel, offer a cost-effective solution for less demanding drilling applications.
