In the course of surveying and calculating the ventilation resistance in mine, potential pressure energy needs to be worked out by using the value of the relative level at the surveying spots. It is usually found according to geological in the process of designing shaft building, developing and mining work. However, the accurate and complete value of level at surveying spots can not be attained because of some object factors. For example, the change of scheme during repairing and construction. Therefore, some trouble and regrets rise. Base on the thinking method of liquid abnormal redundancy flow theory and atmospheric thermodynamic theory, the authors analyze and study the character of atmospheric pressure system and the criterion, design principle of mathematical model about atmospheric depth measurement and surveying instrument is raised.
