3、CTThis design includes of three parts: the general part, special subject part and translated part.The general part is a new design of Sima mine. Sima mine lines in ChangZhi in ShangXi province. The traffic of road and railway is very convenience to the mine. The run of the minefield is41km ,the widt

4、h is about4.5 km，well farmland total area is17.22.The third is the main coal seam. The thickness of the mine is about5.0m in all. The proved reserves of the minefield are 117.8million tons. The recoverable reserves are 113.21 million tons. The designed productive capacity is 3 million tons percent y

5、ear, and the service life of the mine is56.4 years. The normal flow of the mine is 220 m3 percent hour and the max flow of the mine is 300 m3 percent hour. The mineral well gas gushes the deal lower, for low gas mineral well.The well farmland is a single level in an inclined well to expand. Main roa

6、dway makes use of belt conveyor to transport coal resource, and Trackless Tyred Vehicle to be assistant transport. The type of mine ventilation system is two wings diagonal ventilation.The working system “three-eight” is used in the Sima . It produced 330d/a.This design includes ten chapters: 1.An o
