有关煤矿床水文地质勘查类型问题的讨论

A Discussion on Coal Deposit Hydrogeological Exploration Type Partition Issue

水文地质勘查类型的正确划分是矿床水文地质勘查设计的依据,是建立在正确认识矿床水文地质条件基础上进行的。现行规范一股划分为3类3型。随着煤炭资源的不断开发,特别是进入21世纪以来,西部煤炭资源的开发和煤炭资源开采深度不断加大,矿床充水条件发生了变化,主要水害的类型也发生了变化。从煤矿床水害类型、充水条件、勘查方法的选择、地下水赋存空间特征等方面阐述了煤矿床水文地质勘查类型划分的依据和方案,依据矿床充水水源类型和水文地质条件复杂程度将煤矿床水文地质勘查类型划分为5类3型,并提出了相应勘查的工作量,为煤矿床水文地质勘查设计提供了科学的认识方案。

The correct partition of hydrogeological exploration type is the basic thought that guides mine hydrogeological exploration design. It is carried out on the basis of mine hydrogeological condition correct understanding. Current specifications are generally divided into 3 categories and 3 types. Along with continuous coal resources exploitation, especially since the 21st Century, the exploitation of western China coal resources and deepening depth of extraction, water filling conditions changed, main water hazard types also changed. The paper has expounded coal deposit hydrogeological exploration type partition basis and scheme from aspects of coalmine water hazard type, water filling condition, exploration means selection, groundwater hosting space features etc. Based on mine water filling source types and complexity of hydrogeological conditions partitioned the coalmine hydrogeological exploration type into 5 categories and 3 types; put forward corresponding workload. Thus has provided mine hydrogeological exploration design with scientific understanding program.
