EnglishThe prediction of stone ‐ diamond wire interaction is important for the extractive sector, both to improve the productivity and efficiency of quarry work and to avoid dangerous and expensive endeavours of cutting when an unknown stone has to be introduced in the plant.

In particular, in this work the application of this scientific classification methodology to the stone plant has been studied, performing UPV measurements on stone block before their cutting The correlation of ultrasonic measurements by indirect method with the index HK25 allowed to order the stones in classes of workability that correspond to what the owners of the plant used to give to such stones.

| Abstract: | The prediction of stone ‐ diamond wire interaction is important for the extractive sector, both... to improve the productivity and efficiency of quarry work and to avoid dangerous and expensive endeavours of cutting when an unknown stone has to be introduced in the plant. Combining two simple test as the measurement of ultrasonic pulse velocity of the stone and the Knoop micro hardness, a scientific classification of workability have been found. In particular, in this work the application of this scientific classification methodology to the stone plant has been studied, performing UPV measurements on stone block before their cutting The correlation of ultrasonic measurements by indirect method with the index HK25 allowed to order the stones in classes of workability that correspond to what the owners of the plant used to give to such stones. Moreover the correspondence with the in situ cutting parameters has confirmed the reliability of this scientific methodology. |
