固体矿产资源储量半自动化估算方法

三维矿业软件主要通过人机交互的操作方式进行资源储量估算工作,存在操作步骤繁多、易出差错和估算时间长等缺点。在结合Surpac三维矿业软件编制资源量估算报告的基础上,提出了利用Surpac软件二次开发技术编制功能,建立了固体矿产资源储量半自动化估算方法。通过设计符合《固体矿产资源储量估算规程》要求的三维矿体资源储量估算技术流程,利用Surpac软件二次开发的TCL/SCL脚本技术,在Surpac软件基础上开发系列功能执行流程操作。研究表明：除了剖面解译、实体建模和变异函数需要人机交互外,其他所有操作均可利用开发的功能进行自动化处理,使资源储量估算工作整体上达到半自动化程度。将本文提出的方法应用于内蒙古自治区阿鲁科尔沁旗巴彦包勒格银多金属矿资源量估算过程中,并采用地质块段法对该矿床1号银矿体资源量进行估算验证,结果表明2种方法所得估算结果的相对偏差均在合理范围内。由此说明,本文提出的储量半自动化估算方法可靠可行,能够显著提高资源储量估算工作效率,创造了良好的经济效益。
