Abstract: Research actuality and trend on the advanced detecting technology for underground hazards geological body have been summarized in this paper.Author has brought forward several thoughts on main problems existing in application.Different methods combination of seismic reflected wave method and DC exploration are used on different hazard geological bodies.That fast and effect integrative detecting methods,condition,its applied conditions and best observation system are found out by observation and analysis on numerical simulation,model test and underground experiment to improve distance,precision and veracity of advanced detection.
