The increasing use of paste backfill in underground mining makes it necessary to quantify the effect of tailings properties, such as physical and chemical properties, on the performance properties of cemented paste backfill (CPB). The mechanical performance of CPB placed in underground openings (i.e. mine stopes) is often different from the one predicted in laboratory studies even under similar curing conditions of temperature and humidity. This observation is presumably due to the specific consolidation and drain...

This study was aimed to determine the levels of blast-induced vibrations at BayД±rk\"oy town situated in the boundary of BeЕџikd\"uz\"u and being said to be affected by the blasting generated at Korkuthan Quarry being located at the edge of Akhisar Brook in BeЕџikd\"uz\"u in Trabzon. Korkuthan Quarry has assured riprap materials for filling the sea and sea fortification for the construction of Espiye-\cCarЕџД±baЕџД± coastal highway (including Giresun coastal highway) at the scope of The Black Sea Coastal Way Rehab...

General environmental problems generated during blast activities in open pit mining are ground vibrations, air pressure, fly rock, dust and poisonous gases and fumes. In some cases, these problems can be the source of some continual disagreements (fear, right and unrighteous complaints, etc.) on inhabitants living close to a blast-based production in a quarry as well as damage on the buildings situated nearby. In this study, the ground vibrations produced by blasting operations performed at a limestone quarry were...

“The Black Sea Coastal Way Rehabilitation Project” which started seven years ago in order to relief in traffic flow in the Eastern Black Sea Region of Turkey and presently continues to complete their constructions. The project involves the rehabilitation and shortening of the present motorway and hence the construction of new tunnels and riprap material for filling the sea are required in some places. This paper involves one of the blast based tunnel excavations, which is performed for “Yoroz Tunnel” situa...
