About this document
Predicting Fines from Blasting Engineering by Thomas Lawson is a document available to read on EtoBox.
The document presents a new model to predict the proportion of fines (particles less than 1.18mm) generated during blasting. The model is based on analysis of 92 blasting tests on concrete blocks of varying strength. Sieve analysis showed the percentage of fines is directly proportional to the percentage of material in the cylindrical crushing zone around each blasthole. The proposed model combines this relationship between crushing zone volume and fines percentage with a new model to predict the size of th
