摘要
矿政属性数据质量直接关系到矿政总体数据质量以及系统功能的发挥。由于缺乏完整的矿政属性数据定量评价过程,选择准确性、完整性、一致性、现势性4个维度作为数据质量维度指标体系,并针对每个维度指标给出相应的规则约束来定量化描述质量问题,然后利用加权平均分和缺陷扣分法相结合的评价方法,结合某个矿区的储量管理属性数据进行实例分析,分析结果表明该矿区储量数据质量有待提高。
The quality of the source data in mining administration influnces directly the whole and the systematic fumction. Four dimensions： accuracy, completeness, consistency, timeliness are regarded as the index system. The weighted average point method and defect evaluation method are proposed with examples to get the quality evaluation value of basic geological data. The evaluation results indicate that the data quality of rating is not reached, and the quality of data based on geological data needs to be improved.
