在矿石储量计算时,目前求矿体断面面积的方法有:方格米厘纸法和求积仪法两种。用方格米厘纸法数矿体断面面积,工效低,误差大,方法落后。用求积仪法求矿体断面面积,工效虽较高,但不易掌握,误差亦大,且在工作时往往划破图纸。因此,一般野外地质队在计算矿体储量时最常用的是方格米厘纸法。最近我们在学习兄弟队先进经验的基础上,对用重量法求矿体断面面积做了一些试验,工效较快,精度较高,下面作一简介:
In the calculation of ore reserves, the current method of seeking the cross-sectional area of the ore body are: checkerboard method and quadrat meter two. With the square meter centimeter paper number of ore cross-sectional area, low efficiency, error, backward method. Using the quadrature method to find the cross-sectional area of the ore body, the work efficiency is high, but not easy to grasp, the error is also large, and often scratched the drawings at work. Therefore, the general field geology team in calculating the ore reserves is the most commonly used square meter method. Recently, we learn the advanced experience of brothers based on the use of gravimetric method to do some cross-sectional area of the ore body, faster efficiency, higher accuracy, the following to make a briefing:
