Restoration of Coal Mining Areas

In April, I was invited to join the mining restoration expert group, attend and present a set of recommendations at the 9th Sino-American Engineering and Technology Conference in Beijing, China. Prior to the gathering in Beijing, our group went to Anhui to have site visits and technical exchanges with local experts.
