摘　　要：以经山寺矿为例,分别从爆破技术、设备选型、开采顺序、道路规划、排水设计、设备利用率等方面综合分析了中小型设备高强度采矿技术的经济效益和环境效益。实践证明,小型设备高强度开采值得在矿体规模小、数量多、厚度薄、产状复杂的中小型露天矿中推广,有利于控制贫化和损失。The paper, by taking the blasting technology used in Jingshansi open-pit Mines an example, discussed the economic and environmental effects resulted from the employment of small-medium capacity facilities of high ability in terms of blasting technology, equipment selection, mining sequence, road layout, drainage design and equipment operational rate. Practical operation showed that small-size equipment was favorable in terms of the control of ore leaning and losing to open-pit mine of small and medium capacity with small ore body but much quantity occurring in thin strip and complex nature.
