Vietnam Coal industry is facing difficulties such as the decrease of economic efficiency because the domestic coal price declined, the increase of cost of goods manufactured while the opencast mining reserves are declining, the increase of fees, tax. Vietnam has troubles competing with imported coal.
Vietnam produces zinc, nickel, bauxite, coal and manganese, and with the exception of coal, the majority of current mining projects in the country are small or medium in scope. The Vietnamese mining industry is dominated by the stateowned Vietnam Coal and Minerals Industries Corporation (Vinacomin), and has been preparing for a number of major new underground coal mine projects.
1997, coal mining in Hon G ai has used about 2,900ha was lost due to the opening of coal sea ms, the dumping of waste rock (6). The natural forest cover was reduced from percent in 1970
Vietnams coal mining industry is owned and operated by the state coal mining company, Vinacomin (Vietnam National Coal and Mineral Industries Group), which was created by the merger of the Vietnam Coal Corporation (Vinacoal) and Vietnam Minerals Corporati on. Vinacomin operates 95 percent of all coal mines (Le, 2012).
Environmental costs of mining production have to be predicted in a longterm perspective including also postliquidation costs together with taking into account the sources of their covering and models of financing. Keywords: Coal mining production, mine, lifecycle of a mine, environmental costs.
Mine cost estimation may be done at many levels. At first it may be a simple back of the envelope estimation using similar operations to benchmark against. Later it may be decided to use an existing mine that the company owns and factor and compare costs against them.
COAL MINES .This project has been a very good experience for me in the sense that it has Mining Equipment Industry in India 2628 cost of the opencast mining equipment varies from 3050% of the total operational cost in
This article presents cost models for open pit mines, which takes into account cost uncertainty. In this paper, cost uncertainty is considered as cost of under production, and cost of over production.
Although fluctuations in international demand and pricing have put pressure on returns from Vietnams mining industry, the sector remains a magnet for foreign direct investment (FDI), a sign of confidence in its longterm prospects.. Mining attracted FDI totalling in the first half of the year, representing % of all FDI inflows during that period.
b) Underground coal mining currently depth of mining in Vietnam is on 300 meters. Most important in underground mining is to implement more automatic equipment and develop mining safety. Implement systems to control water level in underground mines, training systems for workers to increase they knowledge and work skills.
According to Kentucky Coal Education, continuous miners consist of a series of large cutting shearers and a selfraising hydraulic system that supports the mineshaft ceiling as sections of coal are removed.
