Gold Mine Engineering In China

An iron mine in Yuhezhai, Yunnan, China, and a copper mine in Bahuerachi, Mexico, are going to be constructed, and the plan is to dispose of produced tailings in tailing reservoirs. Engineering design for the two tailing dams is necessary before the mines can be exploited.

Most metal concentrations in the gold mine soil samples exceeded the background levels in Beijing. The spatial distribution of As, Cd, Cu, Pb, and Zn was the same, while that of Cr and Ni was relatively similar. Trace element concentrations increased in larger particles, decreased in the 5074 μm size fraction, and were lowest in the <2 μm ...

Considerable methane resources exist in abandoned coal mines. However, methane extraction from abandoned mines in China is still in the exploratory stage. This study presents technologies and engineering practices suitable for the extraction of gob methane from abandoned mines using surface vertical wells, including methane drainage systems, well bottom loions, and an intermittent .
