Recently, the government has formulated another mining law in order to meet the current mining requirements (the Mining Act 2016) 2013, the Mining and Petroleum Ministry was established by the current government which repealed the previous Act (1940) to create a new and modern bill (the Mining Act 2016).
The mining techniques used in the Gold Rush evolved over time. This evolution tells a much more complex story than it seems at first glance; the change in mining techniques reveals the myth of the Gold Rush. In legend, the Gold Rush was where a poor farmer from New York or Pennsylvania could go, "strike it rich", and return home a wealthy man.
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically 0.6–1.0 m (2 ft 0 in–3 ft 3 in) thick). The longwall panel (the block of coal that is being mined) is typically 3–4 km (1.9–2.5 mi) long and 250–400 m (820–1,310 ft) wide.
The major application of underground surveys is in the construction of tunnels and other underground utilities. The tunnel is constructed when open excavation becomes uneconomical usually when it is more than 20 m. It. Reduces the grade. Shortens the distance between given points separated by a dividing mountain or ridge.
3 Surface mining: Is a type of mining in which soil and rock overlying the mineral deposit (the overburden) are removed. Surface mining is the predominant exploitation method worldwide. Surface mining requires large capital investment (primarily expensive transportation equipment), but generally results in: - High productivity (i.e., high output rate of ore)
An ore silo decouples the footwall and on-reef belt systems. Decline systems for the South UG2 mines comprise four declines on the plane of reef. Mining sections extend over a dip length of 144 m, equating to a vertical interval of 25 m. Strike drives are inclined at 5° above the line of strike.
· The records also document the many mining companies that were operating in the Ballarat East area at the time''. Detail from Plan showing outcrops of reefs on supposed extension of the New Chum line of reef, MAPS 824.365 GBFD 1886. Detail from S.P.

The world''s deepest mine is the Mponeng gold mine in South Africa, which extends to a depth of almost 2½ miles below the Earth''s surface. Mining is a process of extracting minerals and metals from the Earth. These materials occur in their impure form, called ''ores'', which are concentrated in certain regions in the form of ''deposits''.
· Maintaining surrounding rock mass stability of roadways is essential to the safety of deep coal mining. In this study, the No. 2-2092 roadway of the No. 2-209 mining face in Ganhe coal was taken as the target roadway for field analysis. The selected region can be considered a typical area with dominating geological tectonic stress, based on the geological survey and in situ stress results.
