Analysis of Roadway Section Expansion Based on 3DSimOpt
In order to ensure the ventilation safety of Shanxi Huaning Coking Coal Co.,Ltd.and reduce the economic losses caused by improper ventilation,the ventilation resistance of Shanxi Huaning Coking Coal was measured firstly.Then,combined with the mining situation of Shanxi Huaning Coking Coal,the optimization scheme of expanding the section of the total return airway and the return airway of the first panel was proposed,and the area of the specific expansion section was given.Finally,the 3DSimOpt software was used to simulate the optimization scheme and analyze the economic benefits.The results show that the distribution of ventilation resistance in the mine is basically reasonable,the optimization scheme is feasible.
