Dear colleagues,
On behalf of the National Organizing Committee, I am inviting you to participate
in the XVI International Conference of the Open and Underwater Mining ofMinerals, which will be held from 6 to 10 September 2021 at Astor Garden Hotel, theresort "St. St. Constantine and Elena", Varna, Bulgaria.
35 years have passed since the first conference on open pit mining and slope
sustainability in the town of Panagyurishte in 1986, which is proof of the need to holdthis traditional scientific forum. With the inclusion of the thematic area "Underwatermining" the scope of the conference is expanded.
This forum is a platform for the exchange of experience and knowledge ofexperts, scientists and businessmen from around the world, which allows discussions
to be held, presenting innovations, the latest technological developments andproduction methods in the mining industry and construction. In this context, inaddition to discussing scientific and technical issues, the main goal of the conference
is to create a basis for new opportunities for the development of science andbusiness.
We hope that the thematic areas structured by the National Editorial Board will
arouse your interest and provoke you for new searches and solutions to theproblems.
