A New Technical and Economic Model to Calculate Specific Charge and Specific Drilling Using Hole Diameter, Bench Height, Uniaxial Compressive Strength, and Joint Set Orientation

A. Ghanizadeh Zarghami; K. Shahriar; K. Goshtasbi; A. Akbari Dehkharghani

Volume 11, Issue 4 , October 2020, , Pages 991-1005


  Calculation of the specific charge and specific drilling before a blasting operation plays a significant role in the design of a blasting pattern and the reduction of the final extraction cost of minerals. In this work, the information from the Sungun, Miduk and Chah-Firouzeh copper mines in Iran was ...  Read More

A New Method for Forecasting Uniaxial Compressive Strength of Weak Rocks

Hadi Fattahi

Volume 11, Issue 2 , April 2020, , Pages 505-515


  The uniaxial compressive strength of weak rocks (UCSWR) is among the essential parameters involved for the design of underground excavations, surface and underground mines, foundations in/on rock masses, and oil wells as an input factor of some analytical and empirical methods such as RMR and RMI. The ...  Read More

Application of Schmidt rebound number for estimating rock strength under specific geological conditions

S. R. Torabi; M. Ataei; M. Javanshir

Volume 1, Number 2 , July 2010


  A literature review revealed that most of the empirical equations introduced for determination of the uniaxial compressive strength (UCS) of rocks based on the Schmidt hammer rebound number (N) are not sufficiently reliable mostly due to the relatively low coefficient of correlations. This is ...  Read More
