Powerbit Underground is more than a new drill bit. Boosts modern rigs Only then will you experience true drilling productivity. It has more flushing holes and a smarter hole configuration than previous generations of bits.
It will therefore increase the efficiency of rigs with lower water pressure and less effective flushing. Faster, more reliable drilling Powerbit Underground drills up to 15 percent faster than previous Epiroc models, reducing the total cost of ownership considerably. Even so, the true gain comes from what Powerbit Underground will do to your availability and productivity.
How about 20 percent more drill meters before the first regrind and 15 percent more drill meters between regrinds?

Enjoying the satisfaction of trouble-free, uninterrupted drilling that spells more money in your pocket. Full utilization of your rig Drill rigs get most of the attention in mining — and perhaps rightly so.

Estimated delivery Dec The results are processed and yield the total mass of air injected into the pipe, and the proportion which comes from the atmosphere as functions of time. A typical example is presented and discussed in dimensionless terms. It is also shown how the dimensional results can be derived from the dimensionless graphs.
The case of a punctual pipe is thoroughly analyzed. The numerical parameters, namely the size of the domain and the discretization, are discussed. Then, the influence of the pipe properties such as its position and the pumping pressure is illustrated. Finally, the influence of the geometrical parameters relative to the tarp and the embankment are discussed as well as the permeability of the embankment.
For each parameter, all the others being fixed, the dimensionless time for which eta is obtained is determined, and the corresponding dimensionless mass M of injected air is calculated.
