摘要
本文根据作者多年勘探实践,在总结分析近30个供水勘探成果的基础上,对我国北方煤矿区碳酸岩供水水文地质勘探类型;类型划分;供水水文地质勘探的基本特点与原则;不同勘探类型的勘探任务和勘探方法进行了深入探讨。
The karst water ia the early Palaeozoic carbonate rocks is main water filling source and water supply source in the coal mines in the northern China. Based on the requirements of production, the authors summarize the method of exploration and evaluation of the water supply sources for the approximate thirty coal mines and propose the hydrogeological exploration types and methods for water supply in coal mining areas in northern China.First, based on the study of the formation conditions and regularities of karst water in the northern China in combination with the characteristics of water supply and exploration in the coal mines in China, the authors consider the types of karst (exposure, cover, buried) and the conditions of recharge, flow, discharge of karst water as geological basis of classifying the exploration types for water supply. So nine exploration types are obtained. Then, based on developing coal and water simultaneously, regulating water supply and dewatering, and unifying plan, as well as according to the principle of wholeness and synthesization of exploration, the author] discusse the best method of exqloration respectively in the light of different types of water supply exploration, the repuirement water, the period of exploration and the method of evaluation (math, model).
