     Surface Magnetic Resonance Sounding （SMRS） has emerged as a new geophysical technique which allows detecting the abundant degree of hydrogen nucleus in the subsurface directly on the surface.It has been widely used,not only in groundwater exploration and evaluation,but also in water-induced disasters （disasters caused by groundwater,such as dam leakage,landslides and seawater intrusion） forewarning.This paper discusses how to introduce SMRS into the detection and prediction of production safety in underground engineering and achieve MRS exploration in the extreme environments （narrow spaces including tunneling project and coal mining）,which we call it Underground Magnetic Resonance Sounding （UMRS）.To this goal,some challenges has to overcome when UMRS is carried out in underground engineering,including advance detection theories,detection by small coils in narrow space,adaptive signal processing for suppressing electromagnetic noise,quasi-whole space forward modeling and inversion strategies,the processing and inversion of quasi-full space 2D/3D disaster water detection data,as well as joint detection of MRS and TEM methods in complex geological environments like karst aquifers.We also briefly introduce superconducting detection technology and real-time detection technologies for shield and driving methods in underground engineering.
