The rockburst phenomena, came into sight in the early 1900s in the mines of South Africa [3]. Today several deep underground mines in all around the world face the problem of rockbursts. A rockburst is a mining-induced ... The main purpose of rock reinforcement in underground mining is to ensure stability of the rock mass around . E. Kabwe, Y ...
The rock undergoes rapid cooling and rapid depressurization and the vapour dissolved in it is suddenly released and the whole mass swells up into a froth that is immediately consolidated. Small crystals of various minerals occur in many pumices especially feldspar, augite, hornblende, and zircon.

Underground hard-rock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead.It also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. Soft-rock mining refers to the excavation of softer minerals, such as salt ...
Mining first began in the United States in 1867 in South Carolina. Phosphate rock was discovered in central Florida in the 1880s, and because of the extensive, high-quality deposits and lower mining cost, it quickly became the leading phosphate-producing state. Currently, phosphate rock is mined in Florida, Idaho, North Carolina and Utah.
