This paper describes a new technique for the roadway dust control in surface mine. In the method, the emulsified tar liquid with low concentration and the super water-absorbing resin are taken as dust adhesive and sprayed on the roadway. After doing a large number of in-situ experiments, the technique has shown its excellent characteristics on sticking dust, preventing water evaporation and reducing the combined cost of truck transportation.
