Therefore we should first collect basic mineral diagrams shown below as soon as an incident occurs, and reach the minimal requirements of having big-scale mining engineering plan, geologic and topographic map, terrane columnar section and surface-underground contrast plan, satisfying a precision of ±5mm.
Determination on Location of Finished Underground Drill-hole With a view to characteristics of cataclysm period, we shall, based on flooding points and basic data of geologic surveying, locate the finished drill-hole by analyzing underground water level and flood volume, calculate locating coordinates K（X,Y,Z）of finished drill-hole with underground-surveying traverse point and leveling point, or by analyzing mining engineering plan.
Rescue team finally located reasonable underground finished drill-hole after serious analyze, overall research and judgment, according to disaster nature, rescue linchpin, mining engineering plan, comparative diagram of surface and underground situation as well as related geological information, and figured out from relevant maps, the coordinates of the underground finished drill-hole, by which the relevant surface coordinates were brought.
