What Were Some of the Tools That Were Used in the Gold ...

Sep 29, 2017  Panning for gold was also known as "placer mining." Early miners sat by riverbeds, scooping wet soil into shallow metal pans. They swirled the pans, washing away the dirt to hopefully discover particles of gold. Though more complex equipment was eventually invented, pans were still a useful tool to distinguish gold from dirt.

History of coal mining - Wikipedia

Early coal extraction was small-scale, the coal lying either on the surface, or very close to it. Typical methods for extraction included drift mining and bell pits.As well as drift mines, small scale shaft mining was used. This took the form of a bell pit, the extraction working outward from a central shaft, or a technique called room and pillar in which 'rooms' of coal were extracted with ...
