Neural network approach based on a bilevel optimization for the prediction of underground blast-induced ground vibration amplitudes
Autor: Matilde Costa e Silva, F. Durão, Pedro A. Bernardo, Gustavo Paneiro
Publikováno v: Neural Computing and Applications. 32:5975-5987
Due to its technical and economic advantages, the use of explosives in underground rock excavation is widely adopted. However, some safety and, especially, environmental issues arise when using this technique, mainly concerning ground vibrations indu

Comparative stability analyses of traditional and selective room-and-pillar mining techniques for sub-horizontal tungsten veins
Autor: Vidal Félix Navarro Torres, Qiang Xie, M. Matilde Costa e Silva, Carlos Dinis Da Gama, Paula Falcão Neves
Publikováno v: International Journal of Minerals, Metallurgy, and Materials. 18:1-8
The stability and productivity concerning a modification on the traditional room and pillar for a new selective technique at the Portuguese Panasqueira Mine have been described. The traditional room-and-pillar stoping uses 5.0-m wide rooms with 3.0 m

Procedures for geotechnical characterization and economical feasibility studies — application to an underground marble exploitation
Autor: P. Falcão Neves, M. Matilde Costa e Silva
Publikováno v: Journal of Mining Science. 44:92-101
For marble underground excavation it is important to develop a collection of procedures, rules and models in order to collect information to build a database, making it usable and available to all users so that they can make decisions. The informatio
