Brief History of Mining & Advancement of Mining Technology
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
