矿床水文地质勘查类型划分探讨

A Discussion on Mine Hydrogeological Exploration Type Classification

矿床水文地质勘查类型划分是进行矿床水文地质勘查重要环节,是做好和优化勘查设计的主要依据。根据我国煤炭矿山经过几十年的开采,特别是近十几年来大规模开采,煤矿水文地质条件发生了较大变化,现行规范划分方案在实际应用中不基础上,结合《煤矿防治水规定》,提出了矿床水文地质勘查类型划分的新方案:类分孔隙充水矿床、裂隙充水矿床、岩溶充水矿床、老空水充水矿床、地表水充水矿床和复合式充水矿床6个;亚类分顶板充水、底板充分水、周边充水和组合式充水4个;型分水文地质条件简单、中等、复杂和极复杂4个。

The classification of hydrogeological exploration types is a major link in mine hydrogeological exploration and the main basis of exploration design optimization.On the basis of the country＇s coal mining after decades,especially large scale mining in the past 10-odd years,significant changes have been happened in mine hydrogeological conditions,on the basis of currently available classification criterion in practice,combined with ＂Coalmine Water Control Stipulations＂,a new scheme to classify mine hydrogeological exploration type put forward.The classification in the scheme includes six categories： pore,fissure,karst,gob,surface water and compound water filling mines;four subcategories： roof,floor,peripheral and composite water filling paths;and four hydrogeological condition types： simple,medium,complex and extremely complex.
