Ancient Mining Tools and Techniques

Slow-going and dangerous it may have been, but ancient mining techniques were clever. The earliest mines sought cosmetic pigments for funerals. Picks and hammer stones are examples of stone age tools. Later, ancient man discovered metals which provided materials for superior weapons and tools.

Hand Tunneling

Hand tunneling is typically performed by tunnel miners using pneumatic hand tools to excavate the soils and then installing wood and/or steel supports for tunnels 42" OD or larger. For 96" OD and larger hand tunnels, Bradshaw is the utility industry leader in using the NATM/SEM (sprayed shotcrete) hand tunneling method.

In 1858 bench mining replaced the earlier methods of mining. Miners extracted ore in benches or steps, each sixteen to twenty feet deep, creating one, growing open pit, instead of the earlier, small pits and trenches. During the 1870s steam shovels replaced the hand-loading of railroad cars.

Limestone

 · Mining. Limestone has been a valuable resource since Missouri became a state. In early open pit operations, limestone was mined and crushed by hand and removed from the quarries by mules, carts and tramways. Limestone is now mined using surface and underground methods. Surface quarrying is the most common method of producing limestone in Missouri.

Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.
