چکیده انگلیسی

As for the coal seam with high stress, high gas and low permeability, a single technology cannot prevent the complex dynamic disasters. Because of this, the study proposes a new method of pressure-relief and permeability-increase technology of the high liquid–solid coupling blast. Through coal seam injection and charging structure change, the paper fully works out the dual functions of the water and explosion. Using the theoretical calculation, numerical simulation and physical experiments, we obtained that the initial blasting stress, displacement and overpressure of the liquid–solid coupling blast are much better than that of ordinary blasting. The technology has been used in the relative coal mine, and the application results show that the technique has effectively prevented the coal and gas outburst, which has a wide range of application.
