The manual visual inspection of the wire rope can only detect the external broken wire and the rope diameter change of the wire rope. However, due to the invisibility of the internal wear and corrosion of the steel wire rope, the mine technicians cannot accurately and comprehensively judge the use of the steel wire rope during the inspection. Therefore, the mine cannot understand the specific situation of the steel wire rope during the use of the steel wire rope, and replace the rope in time to ensure the safety of the mine and construction personnel. Technically, it is generally recognized that the critical point of strength loss to determine whether the wire rope is safe is 15%. Statistical analysis of more than 8000 laboratories and field records in the United States shows that about 10% of the steel wire ropes in use have a strength loss of more than 15% and are in a dangerous state, while more than 2% have a strength loss of more than 30% and are in a very dangerous state.

The survey also shows that more than 70% of the steel wire ropes that have been forcibly replaced have little or no strength loss; another statistics in Japan show that more than half of the steel wire ropes that have been forcibly replaced have residual strength of more than 90% of the new rope, and many more than 100, that is, in the running-in period. It can be seen that there is a serious waste in the use of wire ropes only according to regulations and forced scrapping.
