Рассмотрены геомеханические задачи, возникающие при формировании отвалов из фосфогипса – специфического материала, образующегося попутно при производстве фосфорной кислоты. Установлены особенности его деформирования при размещении в техногенные массивы инженерно-технических сооружений. Проанализированы модели деформационного поведения пород, с помощью которых можно выполнять прогнозирование геомеханических процессов в отвалах фосфогипса. Приведены результаты численного моделирования уплотнения техногенного массива отвала в объемной постановке. Расчетами обоснована возможность дополнительного размещения в сооружение фосфогипса в объеме 15 % от запланированного проектом.
