Open pit problems in engineering practice / Проблемы открытых карьеров в инженерной практике

This paper describes some mitigation/remedial measures used in Chilean open pit engineering practice to deal with some common pit slope problems. These measures include the use of controlled blasting techniques, slope depressurization and pit dewatering, use of retaining dikes, buttresses and removal of material in unstable slopes, and the filling of pre-existing underground excavations and surface craters.  <...>
