Rock Characterization While Drilling and Application of Roof Bolter Drilling Data for Evaluation of Ground Conditions
(Elsevier, 2015)
Despite recent advances in mine health and safety, roof collapse and instabilities are still the leading causes of injury and fatality in underground mining operations. Improving safety and optimum design of ground support ...
The Prediction of Penetration Rate For Percussive Drills From Indirect Tests Using Artificial Neural Networks
(Southern African Inst Mining Metallurgy, 2016)
Percussive drills are widely used in engineering projects such as mining and construction. The prediction of penetration rates of drills by indirect methods is particularly useful for feasibility studies. In this investigation, ...
The Needle Penetration Test for Predicting Coal Strength
(Southern African Inst Mining Metallurgy, 2017)
The coal strength parameter is used in operations such as the selection and design of mechanical excavators and coal crushing/grinding equipment. However, coring or cutting prismatic specimens from coal for the standard ...
