摘　　要：为查明南阳矿二采区3203工作面范围内可能存在的3号煤层采空积水区、含水层富水异常区及陷落柱的富水性,采用瞬变电磁勘探技术开展了地面物探工作,并结合激发极化法相互解释验证。结果表明,未发现3号煤层采空积水异常区,K8砂岩富水异常区3处,DX13陷落柱在K8砂岩层位上和3号煤层不含水。该技术的应用为预防和控制采空积水区、富水异常区通过导水通道引发的矿井水灾,及后续3号煤层的安全开采提供了地质依据。In order to find out the No.3 coal seam goaf water accumulation area,aquifer water abundance abnormal area and collapse column water abundance that might exist in No.3203 Face of the second mining area of Nanyang Mine,the transient electromagnetic exploration technology was used to carry out the ground geophysical exploration work,and the induced polarization method was used to verify each other.The results showed that there was no abnormal area of goaf accumulated water in No.3 coal seam,three abnormal areas of K8 sandstone water abundance were found,DX13 collapse column occurred on K8 sandstone layer and No.3 coal seam did not contain water.The application of this technology provided a geological basis for the prevention and control of mine flood caused by goaf water accumulation area and water abundance abnormal area through water channel,and the following safe mining of No.3 coal seam.
