Abstract
Based on the continuously improve of coal market and rise of coal price in recent years, we analyze the development of open pit coal mine in China, put forward the standards of transformation from underground into open pit mining, and take Yuanbaowan Coal Mine of China National Coal Group Corp. for case study in this paper. The paper consider that the higher growth speed of open pit mine production in recent years prove that the rising of coal price beneficial to the development of open pit mine. With the total benefit, annual benefit, and net present value of open pit mining are bigger than underground mining, we should actively consider the transformation from underground into open pit mining. The Case studies shown that when the coal price is greater than 241 yuan/t, the Yuanbaowan Coal Mine should exploit by open pit mining, and the terminal condition of transformation from underground into open pit mining will rise with the rising of underground mining rate and open pit mining cost.
