remoção/substituição de cabos
Explanation:
Veja a explicação do que vem a ser "cable mining":

Many CO buildings still in use in large cities were constructed between 1915 and 1930. Such buildings have seen many generations of telephone apparatus and have been "modernized" on a number of occasions. New apparatus is always installed and wired before old apparatus is removed. Telephone cable in CO buildings is supported on "cable rack", which may be as wide as 24 inches. Cable is built up in layers, with the oldest cable being at the bottom of the cable rack; the bottom layer is laced to the cable rack with waxed twine ("12 cord", for the benefit of any WECO people reading this who have "paid their dues" :-) ). Each successive layer of cable is laced to the previous layer. It is not unusual in a large CO to have a SOLID mass of cable 2 feet wide by 2 feet high on a single cable rack.

In the above situation, much of the lower "layers" of cable in a cable rack will be non-working cable which connected apparatus that was removed years ago. The labor necessary to remove such old cable is significant, so usual practice is to just leave the lower layers in place. As a shortage of wiring space develops, an operation referred to as "cable mining" is performed to remove the bottom layers of cable and re-stitch the upper, working layers back to the cable rack, thereby freeing up space for new cable layers.

Cable mining is only done when absolutely necessary, so if space is still available it is not unusual for a cable rack to have bottom layers of cable that are 60 or more years old. Such ituation still exists today in many older metropolitan CO buildings.
