Tóm tắt

Mục đích của bài báo này là cung cấp bối cảnh tổng quan để cho phép hiểu biết sâu hơn về các cơ chế thất bại của đập chứa khoáng sản truyền thống. Nghiên cứu khai thác kiến thức, kinh nghiệm và dữ liệu toàn cầu để thu thập và diễn giải cho việc quản lý an toàn và kiểm soát ổn định địa kỹ thuật của một cơ sở lưu trữ khoáng sản. Động lực cho bài đánh giá này là tạo điều kiện truy cập minh bạch vào bối cảnh và sự hiểu biết về đập chứa khoáng sản. Bài báo này đề cập đến sự hiểu biết cốt lõi về các cơ chế thất bại địa kỹ thuật, và cách mà những cơ chế này dẫn đến sự không ổn định và thất bại của các cấu trúc đập chứa khoáng sản. Nghiên cứu tập trung vào thất bại nền móng, xói mòn bên trong và ống dẫn nước, tràn, thấm nước, hoạt động địa chấn, và không ổn định độ dốc, đồng thời cung cấp cái nhìn về các yếu tố góp phần vào thất bại, cách thức thất bại tiến triển do những điều đó, dự đoán và theo dõi các chế độ thất bại đã nêu, và thiết kế nhằm giảm thiểu rủi ro của chúng.
