| 摘 要： | 以某矿山掘进实例为范本，采用方格网法、断面法、直接切割法计算的土石方量分别为17380．7，17420．1，17598．9m^3，与3种方法计算的土石方量的平均数17466．6^m3进行对比，结果证明采用断面法计算误差最小、相对准确。对露天矿山开采的土石方量及采矿量的计算具有借鉴意义。

| Abstract: | In a certain mine tunneling instance, we use the grid and section method, by directly cutting to calculate the conditions of 17, 380.7, 17,420.1 and 17,598.9 m^3 respectively. Compared with the conditions of the three kinds of method to calculate the amount of average 17 466.6 m^3, the results prove the cross section method to calculate the minimum error, relatively accurate. It is of significance reference to the calculation of quantity of mining for open mining conditions. |
