Take a look at the top six types of underground mining technology. GPS Technology. GPS technologies are making a big difference in underground mining operations. Mines can use them on blasthole drills and electric cable shovels, and they will produce 3-D images of the tracks of the shovel or the drill bit location.
Underground Mining. It is one of humanity's oldest and most impressive engineering activities, extracting an ore or mineral from many hundreds of feet deep underground. From the days of laborers toiling deep inside narrow, rickety and ill-supported tunnels using crude pickaxes and with only candlelight to guide them in their quest for gold ...
Underground Coal Mining. We have an extensive portfolio of products, solutions and software applications to optimise underground mining processes to optimise safety and production performance. In 1990 we deployed the first PED system utilising TTE technology, the first customer to utilse this technology was South Bulli Coal Mine.
Fact #3: Underground Mines Are Really Really Deep. Generally, mines are deep, but underground mines go way deeper than surface mines.

Underground mining operations pose numerous hazards to worker safety and health. Without safety training and proper mining protective equipment, miners risk life-threatening accidents and injuries. Mining personal protective equipment ( PPE) includes clothing and equipment worn to minimize exposure to hazards.
The principal means of access to an underground ore body is a vertical opening called a shaft. The shaft is excavated, or sunk, from the surface downward to a depth somewhat below the deepest planned mining horizon. At regular intervals along the shaft, horizontal openings called drifts are driven toward the ore body.

The average haulage and hoisting costs for these groups ranged from $0.1135 to $0.4025 per ton of ore mined, and the range for 47 individual mines was from $0,086 to $1,848. Elsing has tabulated transportation costs at 66 mines, which show averages by groups ranging from $0,120 per ton mined to $0,556. It is therefore apparent that underground ...
A drilling jumbo (underground mining equipment) usually consists of one, two, or three rock drill carriage, and jumbo drill is essential for blasting and tunnelling. Miners bolt the carriage onto the chassis. In this case, jumbo drill supports the miner's cabin and indeed the engine. The high-tech or modern drilling jumbos are comparatively larger.
