Research on mine anti wind simulation based on Scott-Hensley algorithm

Mine ventilation is an important measure of mine disaster rescue.In order to select the best mine reverse air way, it is necessary to classify and analyze the types of mines with different characteristics.The mine simulation model is created by using MATLAB software, and Scott-Hensley algorithm is written into MATLAB program.Through the simulation program and algorithm, various counter wind modes are simulated and air network is solved.Based on the analysis of the characteristics of mine ventilation system, three types are obtained:single air shaft working mine, multi air shaft working mine with common air inlet section and mine without common air intake section.The results show that the central air shaft and Dongfeng shaft should be used in the whole mine, and the reverse air rate of each air shaft and roadway is more than 40%.Through the theoretical analysis and case simulation verification, it is concluded that the single air shaft mine can directly reverse air to realize the whole mine reverse air; for the mine with shared air intake section and multi air shaft working, the reverse air mode of two air shafts simultaneously should be preferred to realize the whole mine reverse air; in the mine where there is no common air intake section and multiple air shafts, the reverse air of the whole mine can be realized by two air shafts at the same time, or appropriate temporary facilities can be established, and the air shaft can be inverted independently.
