Paper presented at the ISRM SINOROCK 2013, June 18–20, 2013
Paper Number: ISRM-SINOROCK-2013-025
... Abstract Many accidents may occur during tunnel construction because the strata ahead of the working face are not clear; therefore the advanced percussive drilling surveying method is proposed which is one direct convenient, fast and inexpensive geological forecast method. The prediction...

... Abstract Rock cutting mechanisms were used for the prediction of the cutting performance of mechanical excavators in the mid of 1900s. However, rock cutting tests performed in the laboratory both in small and full scales have been successfully applied for the same purpose as a more realistic...

... measured by electric resistance gauges. Plotting of accumulated hit and the accumulated absolute energy versus time shows the absolute energy is a more appropriate parameter to monitor crack propagation and to predict catastrophic failure of specimens than the conventional AE's hit. By comparing the AE...

... specifications of rock and explosive material are influencing the amount of required charge for each application and the conventional methods can not easily incorporate all of them. This research focuses on using "artificial neural networks" for prediction of specific charge based on certain input parameters...

Though measurements have shown that the cracks would not endanger the safety of the dam, sensitivity analysis is still needed to predict the seepage behavior of the dam in partial or complete deficiency of the face slabs on a coupled...

... by using 59 series of accurate triaxial test datasets which are belong to 20 different rock types selected from the literature. It has been shown that the proposed criterion is capable of predicting the triaxial behavior of rocks in both tensile and compressive regions. There are two coefficients...
