Chapter 2: The Environmental Effects of Strip Mining

This section describes the five main types of surface coal mining techniques: area mining, open pit mining, contour mining, auger mining, and mountaintop removal. Underground mining is also considered in this section. Terrain, economics, and custom generally dictate which technique an operator chooses.. All surface or strip mining first removes the overlying vegetation, soil and underground ...

Shaft Sinking . getting down to the opal level

The extent of mining in the clay levels of a mine was often limited because of the difficulty of providing ventilation to remove hot air and dust at the end of a long drive. After the introduction of auger drills for prospecting in the 1980s miners could quickly drill ventilation shafts down to the longest drives to allow more air circulation.
