当矿石被采下后,运至地表,往往由于运輸和其他各方面情况的影响,不能运至冶煉地面被堆积于地表(露天貯矿埸)成为露天矿堆。矿山測量工作者要經常地对露天矿堆进行測量,測出其矿量数,以便供給各需要部门使用。測得数字精确与否,則取决于測量和計算方法。如果矿石規整地堆积于平坦地区,我們用簡單的測量方法便可得到較精确的貯矿数字。然而,矿山大部分是佈于山区,极少出現在平原之上,因此,在矿区內平坦之地很
When the ore is taken down, transported to the surface, often due to transport and other aspects of the situation, can not be shipped to the smelting ground is deposited on the surface (open-pit storage 埸) into an open pit. Mine surveyors should regularly measure open pit mines and measure the amount of mines so that they can be supplied to all departments in need. The exact number of measurements depends on the measurement and calculation method. If the ore is regularly stacked in a flat area, we can get a more accurate number of ore deposits by a simple measurement method. However, most of the mines are located in the mountainous areas and seldom occur in the plains. Therefore, the flat areas within the mines
