AXERA is a compact twin boom electro-hydraulic jumbo designed for fast and accurate drilling in small drives.
This machine has an open cabin, TB40 booms, HLX5 drifters, and a 6/12 TFX feeds. It is suited to rapid twin boom development in smaller drives, but just as comfortable in a larger heading.
Drilling range: 43 to 64mm holes. Voltage. The P&H XPC mining shovel from Komatsu, with a nominal payload of mt (50 st), is found in coal, copper, iron ore, and gold mines around the world.
The benefits of hydraulic use in mining include the fact that the equipment can operate at a specified pressure to take advantage of the force exerted by the larger cylinder to achieve massive force and lift heavier loads.
During mining, double-acting cylinders give the operator more control, particularly when moving rocks and objects downwards.

Hydraulic Mining. Hydraulic mining, or hydraulicking, is a type of mining that uses water to displace rock material or move deposit.
Formerly, the use of a huge volume of water had been urbanized by the Romans to take out overburden and then gold-bearing debris.
mining where a digging machine ﬁlls a bucket with material from a pile or a rock face, transports the bucket cally controls the robot plant through electro-hydraulic valves.
Thus, the signal uc(t) is a control signal for the control valves, while the command u(t) is, in general, a trajectory, i.e. a sequence of desired robot tip posi.For outstanding job versatility, modular construction allows various boom components and hammers to be interchanged using common mounting pins.
