Non-coal-zone in surface coal mine usually causes invalid stripping and increases stripping ratio. In order to solve the problem of increased stripping ratio and transportation distance, and overcome the connection difficulty of coal amount, a new method of leaving an “island” and building a bridge is put forward. A systematic study is made on the optimization transportation system of building a bridge behind the island. At the same time, the procession of building and taking down the bridge and accelerating the path is simulated, and measures for production capacity connection are put forward. The simulation achievements are applied to Shenhua Beidian surface coal mine and the results show that leaving “islands” and building bridges project can reduce the stripping ratio and transportation costs. Moreover, the economic benefit can be improved.
