【摘要】：為探查張北煤礦西二一煤采區(qū)1#探放水斜巷C33上1#順層孔出水水源及巖溶通道發(fā)育情況,采用示蹤試驗(yàn)方法,選擇地面各層位觀(guān)測(cè)孔先后投放NH4Cl、KI、食品紅示蹤劑,井下C33上1#出水孔作為接收點(diǎn)進(jìn)行采樣,分析示蹤劑濃度隨時(shí)間變化特征。結(jié)果表明:井田內(nèi)C3Ⅰ組、C3Ⅱ組灰?guī)r含水層,奧灰含水層及寒灰含水層均存在不同程度的水力聯(lián)系,證實(shí)了該出水水源為石炭系、奧陶系、寒武系灰?guī)r含水層混合水。
[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，
