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.

Another significant benefit lies in their safety. Since they do not use electrical currents, there is a reduced risk of electric shock, which is especially crucial in hazardous environments such as oil rigs or mines. Additionally, the use of compressed air allows for a cleaner working environment, as no oil or fuel emissions are produced Additionally, the use of compressed air allows for a cleaner working environment, as no oil or fuel emissions are produced Additionally, the use of compressed air allows for a cleaner working environment, as no oil or fuel emissions are produced Additionally, the use of compressed air allows for a cleaner working environment, as no oil or fuel emissions are producedpneumatic drilling machine.
