Optimization on uncovering height of south end slope in the first mining area of Ha'erwusu Open-pit Mine
LI Fuping
Abstract：To reduce the secondary stripping amount in mining district II of Ha'erwusu Open-pit Mine, the article optimizes and researches uncovering height of south end slope in the first mining area. Taking the two haulage systems under uncovered inner dumping condition with end slope, which are one side and provisional haulage system in inner dump, the article analyzes all costs and expenses changing condition, and establishes the optimization model for uncovering height based on the minimum cost. Research results show that provisional haulage system in inner dump is the optimum haulage system in inner dumping with end slope uncovered and the reasonable uncovering height is 37 m.
