艰险山区长大深埋瓦斯隧道施工安全风险管控研究OA

To ensure the safe and orderly progress of the drilling and blasting construction process in gas tunnels,based on a gas tunnel,explosion-proof treatment was carried out on electrical and mechanical equipment.Combined with advanced geological prediction and gas monitoring data,technical support was provided for the construction safety of each process of the drilling and blasting operation.With reasonable and effective ventilation methods,the gas concentration was controlled below the safety threshold to ensure the smooth progress of the drilling and blasting operation and the safety of the tunnel construction.
