Abstract：The optimization of gas extraction pipelines can help to rationally allocate pumping capacity,thereby improving gas extraction efficiency.Firstly,an optimization method for gas extraction pipeline based on mine ventilation network solution is proposed,and a specific implementation plan is given.Secondly,the reliability of the extraction pipeline optimization method is analyzed.Finally,the engineering application is carried out.Among them,an optimization strategy is proposed to achieve the pressure distribution of the extraction pipeline containing a variety of gas extraction gas sources by changing the pipeline resistance.The results show that the extraction pipeline optimization method has high reliability,and the error between the network solution results and the measured data is less than 1%.After optimization,the pure gas content of the extraction pipeline in-creased by 9.34%when the optimization target is met.
