Bearing failure demands immediate attention because it can cost as much as $25,000-$50,000 per hour—in lost productivity, unplanned outages and downtime. What's interesting, though, is that the bearing replacement itself is almost always the cheapest part of the failure. A $50 bearing can take down a multi-million-dollar process.

The cut-holes in shaft work may also be termed "sump holes;" by blasting them and cleaning out the muck before blasting, and in some instances before drilling the rest of the round, they provide a sump for collection of water. The round shown in figure 46, D, performs a similar function. Cut-holes in shaft sinking may thus serve a dual purpose.

In shaft sinking and raise driving made by the drilling and blasting method, a free surface and a swelling space are usually made in the form of a bench which is approximately perpendicular to the bottom face or parallel to the wall of the shaft. There are usually three methods: benching method, spiral method, and full-bottom method [8].
