| 摘 要： | 露天台阶开采推进至矿岩交界处时，爆破设计造成的损失贫化对矿山的经济效益影响较大。为科学地进行矿岩交界处的爆破设计和损失贫化控制，结合爆破后冲线位置和爆破漏斗原理，提出矿岩交界处损失贫化控制系统，其功能架构主要包括数据输入、参数设置、损失贫化计算、采样数据拟合、损失贫化查询、优化决策和显示输出等。该系统在三维空间中计算损失贫化，使结果更加准确，并引入最小二乘拟合方法表达后冲线位置与损失贫化的关系，为查询和优化决策提供基础。在VS2010环境下研发出该系统，对内蒙古乌努格吐山铜钼矿的矿岩交界处损失贫化控制试验表明，该系统科学有效。

| Abstract: | Ore loss and dilution caused by blasting design impacts the economic benefit of mine significantly when open pit bench advances to ore-rock border.In order to process blasting design and ore loss and dilution control scientifically,ore loss and dilution control system was proposed combined with back row buffer line and blasting cone.The system consist of data input,parameter setting,ore loss and dilution calculation,sampling data fitting, querying,optimum decision,display and output,and so on.Ore loss and dilution was calculated in 3D space in the system to ensure accuracy.Meanwhile,least square fit was introduced to express the relationship between the location of back row buffer line and ore loss and dilution,which provided the basis of querying and optimum decision.The system was actualized with VS 2010,and the experiment test of an open pit mine in Inner Mongolia shown that it is scientific and effective. |
