Download or read book Rock Drilling Performance Evaluation by an Energy Dissipation Based Rock Brittleness Index written by H. Munoz and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Rock drilling is an essential task in mining engineering and deep exploration industry. In this sense, drilling performance is one of the most important parameters to take into account when evaluating project feasibility and economy. Equipment type and specifications is strongly dependent on predicting the performance of the cutting tool in the field. In this sense, several attempts have been made to assess drilling performance by correlating different rock mechanical and physical properties with the drilling penetration rate.
