Abstract

Tailings pond is used to store the tailings discharged from the mine after separation
and mining. As a potential hazard source with high potential energy, the tailings mortar with
high potential energy after dam break is transformed into high-speed dynamic energy sand
flow to impact the downstream area through energy conversion. In this paper, through the
establishment of a three-dimensional model of a tailings pond, the FLOW-3D software is used
for numerical simulation, and the influence of correlation coefficient on the discharge speed of
tailings mortar after dam break is analyzed, and the relevant migration law is obtained. The
test in this paper can provide a reference for the corresponding disaster and protection
engineering research.

Tailings pond은 분리와 채굴 후 광산에서 방출된 Tailings 을 보관하는 데 사용됩니다. 잠재적 위험원으로서 댐 붕괴 후 높은 잠재적 에너지를 가진 Tailings Mortar는 고속 동적 에너지 및 흐름으로 변환되어 에너지 변환을 통해 다운스트림 영역에 영향을 미칩니다. 본 논문에서는 Tailings pond의 3차원 모델 구축을 통해 FLOW-3D 소프트웨어를 수치 시뮬레이션에 활용하고 댐 붕괴 후 Tailings Mortar의 배출 속도에 대한 상관계수의 영향을 분석하여 관련 이주법을 도출하였습니다. 본 문서의 테스트는 해당 재해 및 보호 엔지니어링 연구에 대한 참조를 제공할 수 있습니다.
