    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, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal, or oil sands.

    Accessing underground ore can be achieved via a decline, inclined vertical shaft or adit. Decline portal Declines can be a spiral tunnel which circles either the flank of the deposit or circles around the deposit. The decline begins with a box cut, which is the portal to the surf

    Levels are excavated horizontally off the decline or shaft to access the ore body. Stopes are then excavated perpendicular to the level into the ore.

    There are two principal phases of underground mining: development mining and production mining. Development mining is composed of excavation almost entirely in waste rock in order to gain access to the orebody. There are six steps in development mining: remove previously blasted material, scaling, installing support or/and reinforcement using shotcrete etceteras, drill face rock, load explosives, and blast explosives. To start the mining, the first step is to make the path to go down. The path i

    One of the most important aspects of underground hard rock mining is ventilation. Ventilation is the primary method of clearing hazardous gases and/or dust which are created from drilling and blasting activity, diesel equipment, or to protect against gases that are naturally emanating from the rock. Ventilation is also used to manage underground temperatures for the workers. In deep, hot mines ventilation is used to cool the workplace; however, in very cold locations the air is heated to just ab

    Some means of support is required in order to maintain the stability of the openings that are excavated. This support comes in two forms; local support and area support.

    Using this method, mining is planned to extract rock from the stopes without filling the voids; this allows the wall rocks to cave in to the extracted stope after all the ore has been removed. The stope is then sealed to prevent access.

    Where large bulk ore bodies are to be mined at great depth, or where leaving pillars of ore is uneconomical, the open stope is filled with backfill, which can be a cement and rock mixture, a cement and sand mixture or a cement and tailings mixture. This method is popular as the r
