The Analysis of the Xiaoqing Mines Ventilation System Based on Network Flow Distribution and Q-H Equilibrium Graph
Based on the ventilation condition and the basic law of ventilation network, the Xiaoqing mines complete detailed ventilation network is computed with the help of the MVSS 3.0, the software of Liaoning technical university and Fuxin Jilan company. Compare with the actual data, the computed result is close to actual data of mine, the largest error is 3. 66%, which is smaller than the 5% and meets the request of the error precision for computing. The high precision computing result provides a favorable platform for simulation of the continued project Xiaoqing mines Q-H equilibrium graph is graphed on basic of the computing result Then, Xiaoqing mines ventilation system is analyzed on basic of its Q-H equilibriuM graph character. The analysis results show that the problem of Xiaoqing mines ventilation system is high resistance in air-return area, the air-return areas resistance of east subarea is 1313. 12 Pa, the airreturn areas resistance of south sub-area is 911.43 Pa The ventilation systems problem limits the potential of ventilation. To solve the ventilation systems problem, the alteration project for Xiaoqing mines ventilation system is presented.
