华北型煤田岩溶充水矿床充水模式及特征

Water Filling Pattern and Characteristics of North China Type Coalfield Karstic Water Filling Deposit

通过对大量华北型煤田矿床水文地质条件研究,从岩溶水系统与下组煤关系入手,分析研究了不同岩溶水系统模式的充水条件和同一岩溶水系统模式不同系统位置充水条件,认为华北型煤田充水条件取决于岩溶水系统模式、构造特征及功能位置,据此将华北型煤田岩溶充水矿床充水模式归结为滞流活化型、单斜内部型、单斜边缘型、块断型、向斜内部型、向斜边缘型等6种,并进一步根据充水通道的不同将其分为滞流活化型陷落柱等15种亚型。同时对其特征进行了概略性总结。

On the basis of large amount North China type coalfield hydrogeological condition research data, with a view to the relation- ship between karst water system and lower group coal seams, analyzed water filling conditions of different karst water systems and in same karst water system with different positions. The result considered that the water filling condition of North China type coalfield is de- pendent upon karst water system mode, structural feature and functional position. Accordingly, come down the North China type coal- field karst water filling patterns into 6 types of stagnation activating, monocline internal, monocline margin, block faulting, syncline inter- nal and syncline margin, and then according to different water filling channels divided into 15 subtypes such as stagnantion activating subsided column subtype etc. Meanwhile, briefly summed up their characteristics.
