As technology progressed, coal mine tools underwent a transformation. The introduction of pneumatic machines in the 19th century revolutionized coal extraction. Devices like the pneumatic pick, powered by compressed air, significantly increased the speed and efficiency of coal cutting. This marked a shift from sheer human effort to mechanical assistance, reducing the physical strain on miners and paving the way for more substantial excavations This marked a shift from sheer human effort to mechanical assistance, reducing the physical strain on miners and paving the way for more substantial excavations This marked a shift from sheer human effort to mechanical assistance, reducing the physical strain on miners and paving the way for more substantial excavations This marked a shift from sheer human effort to mechanical assistance, reducing the physical strain on miners and paving the way for more substantial excavationscoal mine tools.
