A long borehole based automatic gas extraction system is proposed to address the technical challenges of gas extraction in coal mine overburden fracture zones. The system integrates functional modules such as drilling layout optimization,intelligent extraction equipment,real-time monitoring and warning,and data processing analysis,achieving automation and intelligence of the gas extraction process. Through on-site verification in a high gas mine,it has been proven that the system can effectively improve the gas extraction rate and efficiency,with a cumulative gas extraction of 2.3002 million m3 in 30 days and an extraction efficiency of 85.9％. It has significant social and economic benefits.
