In order to effectively control the floating coal dust in the underground mine,based on the synergistic theory between surfactants and magnetization,some experiments were carried out to measure the characteristics of solution under the various experimental conditions,such as surface tension,contact angle and dust suppression properties of solution,which validated that the magnetization can have the effective effect on the dust wettability of solution.And a compound surfactant was acquired,inducing excellent synergetic effects with magnetization.Additionally,the optimal magnetization parameters were confirmed by the above mentioned experiments,e.g.a magnetic intensity of 350 mT and water flow velocity of 4 m/s;while combining the efficiently magnetic methods of the interlaced arrangement of inside and outside magnets and a spiral propulsion magnetization of water flow,the magnetic device and system were propose
