我国固体矿产勘查钻孔质量评价指标分析及黑龙江省地方标准的制定

Analysis of Solid Mineral Exploration Borehole Quality Assessment Index of China and Development of Provincial Standard of Heilongjiang

钻探是矿产勘查的主要手段之一,钻孔质量对资源评价、矿山设计意义重大。本文回顾了我国各行业地勘部门钻探质量评价标准、办法制定的发展历程,比较分析了各部门钻孔质量分级标准应用现状,指出了当前存在钻孔质量评价标准不统一、不同规范不能有效衔接、质量考核文件格式不统一、生态环境保护执行不力等方面的问题。在此基础上,介绍了黑龙江省地方标准《非煤固体矿产钻孔质量要求》(DB23/T 2072-2018)采用的指标评价体系和主要特点,提出了行业主管部门应尽快组织制订钻孔质量标准的建议。

Drilling is one of the main technical means for mineral exploration,and the quality of drill holes is of great significance to the resource evaluation and mine design.This paper reviews the history of the development of drilling quality assessment standards by various geological exploration departments,and by comparing the application status of the drilling quality classification standards,it raises some issues below:the existing drilling quality evaluation standards are not unified,different specifications are not compatible,the quality assessment document formats are not unified,and the ecological and environmental protection is lenient.It then presents the index evaluation system and main characteristics of the provincial standard of Heilongjiang Drilling Quality Requirements For Non-coal Solid Minerals.It is proposed that the competent authorities of the industry should organize the formulation of the drilling quality standard as soon as possible.
