基于华北型煤田岩溶充水矿床充水模式的勘查模式

摘要

The selection of hydrogeological exploration means for North China typed coalfield karst water filling deposit is mainly based on primary hydrogeological issues existed. To exploration area, especially new areas, the hydrogeological condition complexity determi⁃nation based on current specifications has certain ambiguities. For this reason, the authors have systematically analyzed North China typed coalfield karst water filling deposit models[1] main hydrogeological issues and corresponding main exploration means, it comes down to drilling-geophysical prospecting-experiment, investigation-geophysical prospecting-drilling, geophysical prospecting-drill⁃ing-investigation, and geophysical prospecting-investigation-drilling four models. That has great practical significance to guide North China typed coalfield karst water deposit exploration.%华北型煤田岩溶水充水矿床水文地质勘查手段的选择依据主要是矿井存在的水文地质问题，对于勘查区特别是新的勘查区，确定水文地质条件复杂程度依据现行规范有一定盲目性。通过分析华北型煤田岩溶水矿床充水模式的主要水文地质问题，提出了相应的勘查手段，将其归结为钻探-物探-试验、调查-物探-钻探、物探-钻探-调查、物探-调查-钻探等4种模式，对于指导华北煤田岩溶水煤矿床水勘查具有重大的现实意义。
