Based on the principle of graph theory, this paper discusses the basic theory, principle and calculation of working conditions, optimal control and adjustment of mine ventilation system under normal and certain abnormal conditions, and puts forward the following conclusive opinions: 1. Ventilation Network In the figure, the air volume of the branches is uniquely determined by the air volume of each string of the Yu tree; 2. The necessary conditions for effective control of the ventilation network of the mine are that the number of adjustment facilities is equal to the number of remaining trees of the grid and arranged in the corresponding chord; 3. Ventilation Network The necessary condition for the regulation calculation is that the air volume of all the arcs is known. 4. The sufficient and necessary condition for the natural distribution subgraph in the ventilation network diagram is that the unknown air volume arc exists in a concentrated way to form a subset of the circuit. In addition, a brief introduction of the computer algorithm of the subject is given.
