矿产储量计算是地质勘探和矿山设计部门十分繁重的任务之一.在地质勘探阶段,常用断面法计算矿产储量.由于圈连矿体的随意性及计算公式的局限性,使计算的储量常产生误差.当钻孔偏离剖面线或钻孔见矿点偏离剖面线较远时,用断面法计算储量,会因为钻孔见矿位置难于准确表示在剖面上,至使降低对矿体形态的控制程度而造成较大的储量误差.其次,用断面法计算矿产储量必须绘制大量图件和编制繁多的表格,因而耗费大量人力、物力,使计算周期冗长.所以,计算矿产储量的断面法亟需改进. 本文提出的三维块段法是通过建立三维块段模型,直接利用原始勘探资料进行储量计算的方
Mineral reserves calculation is one of the most important tasks of geological exploration and mining design department.Geological exploration stage, commonly used section method to calculate mineral reserves.Because of the arbitrary nature of the encircled ore body and the limitations of the calculation formula, the calculated reserves often occur Error.When the borehole deviates from the profile line or the borehole is deviated from the profile line, the cross section method can be used to calculate the reserves because it is difficult to accurately represent the position of the ore on the cross section through the borehole, so as to reduce the control over the shape of the ore body Degree and cause greater reserves error.Secondly, the calculation of mineral reserves by the cross-section method must draw a large number of maps and the preparation of a large number of tables, which consume a large amount of manpower and material resources, the calculation cycle lengthy Therefore, the calculation of mineral reserves section method Improve.The three-dimensional block method proposed in this paper is through the establishment of three-dimensional block model, the direct use of the original exploration data for the calculation of the square
