ПОЛЕВЫЕ ИСПЫТАНИЯ ОСАЖДЕНИЯ ЖЕЛЕЗОРУДНЫХ ХВОСТОВ В ВЕРХОВОМ ОТКОСЕ НАСЫПИ FIELD TESTING OF THE SEDIMENTATION BEHAVIOR OF SORTED IRON TAILINGS IN AN UPSTREAM EMBANKMENT PROCESS

Аннотация


Безопасность и устойчивость верховых откосов насыпных дамб хвостохранилищ зависят от таких факторов, как уклон насыпи, гранулометрический состав и механические характеристики грунтов, формирующиеся в процессе гидравлической сортировки хвостов. Для определения гидравлических и геотехнических параметров железорудных хвостов обогащения проведены полевые модельные испытания
процесса осаждения и сортировки при наращивании дамбы обвалования. Проанализированы изменения уклона насыпи, давления грунта и поровой воды, прочности на сдвиг массива хвостов и гранулометрический состав отходов в процессе их гидравлической сортировки.
