Introduction

During the mining process, temporary water storage facilities (non-permanent water conservancy projects) are built to meet production, safety or ecological needs. They are used for short-term storage and regulation of water resources, and need to be demolished and the site restored after the project is completed.

Features

1. Temporality: Service life ≤ mining project duration (usually 1-10 years);

2. Functionality: Adapt to the special needs of mining scenarios;

3. Recoverability: A decommissioning, demolition and ecological restoration plan must be formulated.

Structure

earth dam type、stone masonry dam type、concrete dam type、steel structure type、geomembrane anti-seepage type

Applications

1. Storage of process water for open-pit / underground mining (e.g., water for drilling, blasting, mineral processing, and dust control).

2. Flood control and drainage during rainy seasons (intercepting surface runoff to prevent water accumulation in mining areas).

3. Temporary storage of mine wastewater / tail water (for reuse after treatment or discharge up to standard).

4. Water resource reserve in arid regions (to ensure continuous production).

5. Ecological water replenishment (temporarily supporting vegetation irrigation around mining areas).
