Analysis of raw material losses in sawing stone blocks into facing products

Based on the world practice, the data are presented for volumes of extraction and losses of raw material in manufacturing of facing products from natural stone. The analysis of raw material losses is performed depending on volume of blocks to be sawn. A mathematical model is developed and dependences are obtained for the estimation of the raw material losses at sawing up blocks and the yield of facing plates. The expediency is established for production of final facing materials directly in a deposit by cutting out from a stone mass.__________Translated from Fiziko-Tekhnicheskie Problemy Razrabotki Poleznykh Iskopaemykh, No. 5, pp. 104–109, September–October, 2004.
