摘要
通过野外实际调查和长期观测,对黄泥洞泉水的流量变化、出口处沉积物的特征进行了详细的描述.根据该泉水的洞内结构与形状,将泉水的岩溶发育划分为三个阶段,并对各阶段岩溶发育特征进行了研究.综合分析认为,该泉水形成主要有三大要素:一是有溶道中地下水的长期补给;二是洞内岩溶发育成溶洞等洞穴,具有虹吸结构;三是泉水从垮塌的杂乱岩石中流出,洞内地下水排泄不畅.最后指出,岩溶间歇泉出口处的流量并不是该泉水的真实流量,其流量不适用于水动力学法计算未来矿井涌水量.
Abstract
Through field investigation and long-term observation,described flow rate variation and outlet sediment characters of the Huangnidong geyser in detail.According to cave structure and shape,divided the karstic development of the geyser into 3 stages and studied karstic development characteristics of each stage.A comprehensive analysis considered that,the generation of the geyser mainly has 3 major factors: the first is long term groundwater recharging into the karst channel; the second is particular karst caves have been provided with siphon functions; the third is geyser flow out from collapsed cyclopean ripraps,difficult drainage of groundwater in caves.Finally the author pointed out that the flow rate of the geyser outlet is not the geyser's true flow rate,and unfit to estimate future mine inflow through groundwater dynamic method.
