Qinghai: Ecological Protection, Restoration, and Remediation Undertaken at 68 Historically Abandoned Mines

On the 8th, reporters learned from the Qinghai Provincial Department of Natural Resources that 68 historical mine‑related ecological restoration projects, including those in Zhongling Village, Jingyang Town, Datong County, Xining City, meet the eligibility criteria for support under the 2021 central government transfer payments—specifically, the special fund for key ecological protection, restoration, and governance—and have been included in the 2021 list of priority ecological governance projects.

Digital twins will become a key tool for the mining industry to achieve ESG goals.

Jeff Hamilton, Senior Director of Brand Strategy and Alliances at Dassault Systèmes, stated that digital twin technology leverages software to reconstruct physical entity models, enabling mining companies to place themselves at the heart of sustainable supply chains and achieve end-to-end traceability of minerals—from the mine to their final applications.

Carbon fiber for fiberglass products

Carbon fibers and graphite fibers both exhibit excellent mechanical properties. The tensile strength of graphite fiber is approximately twice that of glass fiber, while its thermal resistance far surpasses that of glass fiber. Fabrics woven from graphite yarn retain high mechanical strength even when heated to 2,500°C. Consequently, when used as a reinforcing material in fiberglass‑reinforced plastics, they enable the production of high‑performance composites with outstanding resistance to high temperatures and ablation.

General Introduction to Anti-Corrosion Engineering Solutions

Introduction to the Construction Process: General Overview of Pool Anti-Corrosion Works. The specific construction of a surface‑coated glass‑epoxy steel anti-corrosion system—commonly referred to as the “three‑cloth, five‑oil” method—is divided into the following steps: 1. Preparatory Work: - Prior to commencement, ensure that the cement floor is completely dry and that its strength has reached at least 80% of the design value. Verify that the substrate is level, with deviations no greater than 1–1.5 mm per meter, and that the surface is clean and dry before proceeding with the application of the primer coat. Avoid carrying out work during the hottest part of the day. - Prepare all required fiberglass‑reinforced plastic (FRP) materials and construction equipment, and implement basic fire‑safety measures. Ensure that personal protective equipment and safety precautions are in place, and develop a detailed construction plan.
