Abstract：Under the background of the construction of intelligent mine ventilation system,online determination of wind resistance of the whole mine is one of the important technologies.The key to building an intelligent ventilation system is to obtain accurate and reliable ventilation parameters,but to achieve intelligent ventilation systems throughout the mine,a large number of perception sensors need to be installed.In order to solve the problem of online determination of wind resistance in resistance mines on the basis of limited sensors,the im-proved minimum tree principle is used to determine the optimal layout scheme of wind speed sensors.Starting from the principle of"wind measurement and resistance",the nodal pressure is used to meet the wind pressure balance of the circuit,the minimum number of pressure sensors installed in the wind network is determined,and the installation site is optimized,so as to obtain the branch air volume and node pressure wind pressure monitoring data of the whole mine.The above principle is applied to the ventilation network diagram of 23 branches and 16 nodes,and the results show that the wind resistance error is within 5%.
