History of Mining Technology. In the beginning, miners used primitive tools for digging. Mining shafts were dug out by hand or using stone tools, making the entire process very lengthy. Eventually, the pick and hammer were replaced with fire to clear tunnels and reach greater depths at a faster rate. By piling a heap of logs near the rock face ...
