为了查明张集矿A组煤层底板灰岩含水层突水通道及含水层水力联系,向奥陶系灰岩含水层投放NH4Cl、KI 2种示踪剂,同时向寒武系灰岩含水层投放食用胭脂红示踪剂,并在在突水点处按一定间隔采集样品,分析离子浓度及分光度随时间变化关系曲线,研究表明:奥陶系灰岩含水层中存在4条岩溶通道,寒武系灰岩含水层存在3条岩溶通道,且不同含水层水力存在一定的水力联系,突水水源为多种水源混合。
In order to find out the hydraulic connection between the limestone aquifer aqueduct and the aquifer in the coal seam floor of the A group of Zhangji coal mine, two tracer of NH4Cl and KI were put into the Ordovician limestone aquifer and the Cambrian limestone aquifer The edible carmine tracer was put in place and samples were collected at certain intervals at the water inrush point. The curves of ion concentration and spectrophotometry with time were analyzed. The results show that there are 4 karst channels in Ordovician limestone aquifer, There are three karst passages in the Cambrian limestone aquifer, and there is some hydraulic connection between the different aquifer hydraulic forces. The water inrush is a mixture of a variety of water sources.
