摘要
精确的矿石储量估算是矿山设计、生产及管理的重要依据,地质统计学方法由于其考虑了区域化变量的结构性和随机性的二重性特征,获得了日益广泛的应用。然而,由于地质统计学方法是建立在一定假设的基础上,再加之各种主观因素的影响,地质统计学储量估算往往存在一定的偏差。在总结前人工作及地质统计学储量估算工作经验的基础上,认为影响估值精度的因素可归纳为两个方面:矿床具体条件及取样情况(客观因素);储量计算时的处理手段和方法(主观因素),提出克服主观因素是解决偏差产生的重要途径,对主要主观因素的影响及解决办法提出了较为详尽的论述。
The accurate reserves estimation is important for the design, producing and management in a mine. Geostatistics technology has been used more and more because it considered structural and random characters of regional variables. However, as the methods are based on some assumptions, additionally, affected by many objective factors in the courses of reserves estimation, the results are always inaccurate. The authors consider that the effective factors can be reduced in two aspects: the actual deposit and sampling instance that belongs to objective factors, the disposing methods in reserves estimation that belongs to Subjective factors. Based on this thought, it has been put forward that overcoming the Subjective effect is a main solution to the inaccuracy; meanwhile, a detailed discussion for the methods to solute these questions is given.
