Abstract: For the poor dust control efficiency and wettability of the solution spray in the fully mechanized mining face, the dust control technology using surfactant-magnetized water was proposed. The strong wetting properties of the surfactant-magnetized water were measured, of which contact angle, dust deposition time and dust control efficiency have been greatly improved than that of the untreated water. Meanwhile, the preparation process of the surfactant-magnetized water was put forward. The field application results in the 12100 fully mechanized mining face, Shoushan No. 1 Mine showed that the dust removal technology using surfactant-magnetized water can effectively reduce the dust concentration in the working face. The average dust removal efficiency of respirable dust and total dust at different measuring points reaches 84.67% and 88.52%, respectively, effectively improving the working environment of underground workers.
