Conference on mining and dumping scenarios for Deo Nai, Coc Sau and Cao Son coal openpits

The conference on mining and dumping scenarios for Deo Nai, Coc Sau and Cao Son coal openpits was held at the head office of Vinacomin Industry Investment Consulting Joint Stock Company (VIMCC) on the morning of October 29, 2013.

The conference was attended by Members of the Management Board of Vietnam National Coal-Mineral Industries Holding Corporation Limited (Vinacomin) Nguyen Van Kiem and Pham Van Mat, President & CEO of Vinacomin Le Minh Chuan and Deputy President of Vinacomin Vu Thanh Lam; specialists of Planning Department, Investment Department, Department of Science, Technology and Strategy, Department of Mining Technology, Department of Natural Resources and Department of Environment of Vinacomin; Director of Vinacomin Institute of Mining Science and Technology Nguyen Anh Tuan; Chairman of the Management Board and Director of Vinacomin Deo Nai Coal JSC Pham Hong Tai; representatives of  Coc Sau and Cao Son coal companies; Chairman of the Management Board of VIMCC Do Hong Nguyen, Deputy Directors Le Van Duan, Nguyen Viet Cuong, Le Viet Phuong and experts of VIMCC.    
                     

To help large coal openpits of Cam Pha region (Deo Nai, Coc Sau, Cao Son, Khe Cham II and Dong Da Mai) have a proper mining order in order to make the most of space of temporary dumps and internal dumps, limit the use of external dumps, synchronize the deepening speed, have the most proper transporting distance and limit the mobilization of much investment at the same time, Vinacomin assigned VIMCC to work out “Proper mining solutions for coal openpits of Cam Pha region” which were approved by Vinacomin according to the Decision No. 1977/QD-Vinacomin on September 12, 2012. However, in 2012 and early 2013, there were fluctuations in the domestic and international economies which were disadvantageous to the mineral exploitation industry, leading  to a decrease in mineral consumption  and increase in prices of such input fuels as petrol and electricity. To deal with such problems, VIMCC studied and worked out mining and dumping scenarios for Deo Nai, Coc Sau and Cao Son coal openpits.

Based on the survey data and techno-economic conditions of coal openpits, VIMCC proposed two scenarios as follows:

Scenario 1: Coal selling prices according to the official document No. 3935/Vinacomin-KH. The coal consumption cost price would be calculated by section’s cost price. The input prices of direct sections and other sections would increase by 5%/year and 3%/year respectively (based on Vinacomin’s instructions).

Scenario 2: Coal selling prices according to the official document No. 3935/Vinacomin-KH. The coal consumption cost price would be calculated by section’s cost price. The input prices of direct sections and other sections would increase by 3%/year and 1%/year respectively (based on the proposal of the consulting company and related companies). There were two options as follows:

-         Option 1: Considering the independent mining order of openpits

+ Solution 1A: Accounting all costs to cost prices

+ Solution 1B: Putting a part of overburden into capital construction overburden

-         Option 2: Considering the possibility of combined mining of openpits

+ Solution 2A: Using Via Chinh area as a temporary dump

+ Solution 2B: Using Thang Loi area as a temporary dump

At the conference, the above-mentioned scenarios of VIMCC were discussed openly and in a high sense of  responsibility. All the participants of the conference expressed their strong agreement to the scenarios.

Concluding the conference, President and CEO of Vinacomin Le Minh Chuan approved scenario 2, option 1 and solution 1A proposed by VIMCC.  At the same time, he highly valued the sense of responsibility of staff of VIMCC and related companies who made every effort to work out the mining and dumping scenarios for Cao Son, Coc Sau and Deo Nai coal openpits for sustainable development of coal openpits of Cam Pha region.
