Based on spraying bubble of fully mechanized mining machine and spraying in the back without the ability to reduce dust content in the 15129 working face mining of Tucheng Mine, water drilling technology was adopted, the number of water injection hole and pressure were optimized. The site experiment showed that water injection hole number more than 10 exclusively with water drilling and water pressure over 6 MPa exclusively with water pressure, without obvious dust-laying effect, but 8 water injection hole and 6 MPa water pressure were equipped, with the economical and best dust-laying effect.
