Resistance measurement and analogue simulation of ventilation system in Xiagou Coal Mine
ZHANG Zhi-rong
Abstract：According to the current situation of ventilation system in Xiagou Coal Mine,the analogue simulation based on ventilation system resistance measurement was proposed.Through coal mine measurement,the distribution of ventilation resistance in 401 mining area and 404 mining area was calculated,and numerical simulation of the ventilation system was carried out using MATLAB software,combining with graph theory and fluid mechanics.The calculation results show that total resistance of 401 mining area is 1265.88Pa,relative error 4.8%;total resistance of 404 mine area is 2537.38Pa,relative error 3.2%;the numerical simulation results is correct,according to the comparison with the measured data.
