Research On Mining Solution Of Da Shiquan Open Pit Coal Mine

Open-pit coal mine mining plan research is an important part of the coal mine development and construction, which.is in order to make the production of coal mine get optimal economic efficiency, optimal overall vision of social benefits and environmental benefits in the future.According to the raw coal price of coal mine near, the maximum economic and reasonable stripping ratio was calculated. According to the average coal mine working line length, working line annual push strength, thickness of coal seam and coal bulk density, from the aspects such as technology, economy and market analysis,we determine the reasonable production scale mine. According to the terrain and mine coal seam occurrence of geometry, the outdoor recoverable range of the mine area is divided into four mining area. Through the four coal and rock mining area, the average stripping ratio, infrastructure V-P curve of quantities research in this paper, we study the mining process. Scheme that advantages of a mining area as the first mining area is larger.Eventually we determine the ore mining area of the mining sequence for first mining area, second mining area, third mining area and forth mining area. According to equilibrium after the production stripping ratio, we calculated the equipment quantity reaches producing period, and arrange the production plan.
