【摘要】：为探查张北煤矿西二一煤采区1#探放水斜巷C33上1#顺层孔出水水源及岩溶通道发育情况,采用示踪试验方法,选择地面各层位观测孔先后投放NH4Cl、KI、食品红示踪剂,井下C33上1#出水孔作为接收点进行采样,分析示踪剂浓度随时间变化特征。结果表明:井田内C3Ⅰ组、C3Ⅱ组灰岩含水层,奥灰含水层及寒灰含水层均存在不同程度的水力联系,证实了该出水水源为石炭系、奥陶系、寒武系灰岩含水层混合水。
[Abstract]:In order to explore the development of water source and karst channel of No. 1 downstream hole in No. 1 drainage inclined roadway of Zhangbei Coal Mine, NH4Cl,KI, food red tracer was put into observation hole of every layer on the ground by using tracer test method, in order to explore the development of water source and karst channel of No. 1 downstream hole in No. 1 drainage inclined roadway of Zhangbei Coal Mine in West Eryi Coal Mine. The 1 # outlet hole on C33 is taken as the receiving point and the characteristic of tracer concentration with time is analyzed. The results show that there are hydraulic connections in C 3 鈪，
