DOI: 10.1007/s10064-017-1175-4
Abstract: Rock mass classification systems are commonly used to evaluate the likelihood of instability in mining environments. Most frequently used classification systems are the rock mass rating (RMR), geological strength index (GSI), and the Q-system. These… read more here.

DOI: 10.1007/s10706-017-0390-x
Abstract: We develop a database containing 95 historical natural slope and 37 tailing dam failures triggered by earthquake. The database analyses show that earthquake-triggered failures in natural slopes are mostly initiated in the narrow ridges. We… read more here.

DOI: 10.1007/s11600-019-00268-4
Abstract: Ground vibration is one of the most undesirable effects induced by blasting operations in open-pit mines, and it can cause damage to surrounding structures. Therefore, predicting ground vibration is important to reduce the environmental effects… read more here.
