采用体积法进行石灰岩总量预测时,大量而繁锁的工作是根据不同的出露情况,计算地形基准面以上的石灰岩体积。基准面以上的石灰岩形态基本可分两种:锥体(图1)与棱台(图2)。不论何种形态,其体积计算均与块段垂向断面上灰岩层面积有关。简言之,横断面面积计算乃是整个计算工作的重要环节。 When volume method is used to predict total amount of limestone, a large amount of work needs to be done to calculate the volume of limestone above the terrain datum according to the different exposure conditions. There are basically two types of limestone above the datum: pyramids (Figure 1) and pyramids (Figure 2). Regardless of the form, the volume calculation is related to the limestone area in the vertical section of the block. In short, cross-sectional area calculation is an important part of the calculation.
