Повышение эффективности транспортных трубопроводов закладочного комплекса применением полиуретанового покрытия

Одной из основных причин недостаточной эффективности закладочных комплексов горных предприятий является интенсивный гидроабразивный износ его транспортных трубопроводов, который влечет за собой изменение шероховатости внутренней поверхности, что в свою очередь определяет потери напора при гидротранспортировании. Замена изношенных трубопроводов на новые, а также повышенное энергопотребление являются основными статьями расходов при эксплуатации гидротранспортных систем закладочных комплексов. В статье представлены результаты исследований поверхности трубопроводов закладочных комплексов, установлено влияние шероховатости внутренней поверхности трубопровода на удельные потери напора, что позволило произвести оценку экономической эффективности замены толстостенных стальных труб на металлические с футеровкой полиуретаном. Выполнен сравнительный расчет затрат на укладку и эксплуатацию сроком 10 лет стального толстостенного трубопровода и стального трубопровода с внутренним полиуретановым покрытием, учитывающий расходы на закупку, монтаж и замену труб, а также траты на электроэнергию для транспортирования закладочной гидросмеси по этим трубам.
