Abstract:
For the features of long haul distances and high motor transport haulage cost during internal dumping in near horizontal surface coal mine with seasonal stripping，on the basis of theoretical calculation and analysis，the paper proposes a thought that building temporary connection bridges to optimize in-pit haulage system development. And an techno-economic analysis about form and building requirements of temporary connection bridges is made，the parameters model and optimization algorithm of temporary connection bridges are provided. The research production has been practical applied to West 2 surface coal mine of Mengdong energy holdings co.，LTD. The results show that building temporary connection bridges to optimize in-pit haulage system development generates remarkable economical benefits.
