露天采矿的生产工艺包括穿孔、爆破、将矿石装运至破碎机进行破碎,将废石运往排土场排弃等项作业,日益增涨的能源费用已成为很多矿山企业能否获取利润的关键因素。为了更多地了解各个不同采矿作业中能耗的形式,研究了一些假设的矿山。本文对一个命名为大伯格矿的假设露天矿的能耗进行了评价,并对第五年的开采情况进行了分析。能耗的度量方法文献中一般采用两种能耗度量法,一种称为有用能耗,或称净能耗,表示燃料的直接理论热值及外购的有用电能。另一种称为总能耗,它与净能的区别仅在于它包括了发电过程 Open-pit mining processes include perforation, blasting, crushing ore to crusher and dumping waste rock to dump, and the rising energy costs have become the key factor for many mining companies to make profits . In order to learn more about the forms of energy consumption in various mining operations, a number of hypothetical mines were studied. This paper evaluates the energy consumption of a hypothetical open pit mine named Bigburger Mine and analyzes the fifth year of mining. Measurement methods of energy consumption Two kinds of energy consumption measurement methods are commonly used in the literature, one is called useful energy consumption, or net energy consumption, which represents the direct theoretical calorific value of fuel and the purchased useful electric energy. Another known as total energy consumption, it differs from the net energy is that it includes the power generation process
