Abstract: Protective layer mining is one of the most economic and effective regional outburst prevention measures. The key problem encountered in extracting protective seam mining is to study protective layer mining technology and the protective effect. The paper to predict the protective gas emission during mining, design reasonable gas extraction solution as the foundation, use of protective layer mining thin coal seam outburst elimination technology, studied the elimination of protective layer mining effect. Results showed that 11030 protection layer after the working face mining protective layer are fully discharge pressure and the gas release, in the unloading zone outburst elimination effect is obvious, as a protective layer mining condition of coal and gas outburst in the outburst mines of effective prevention and control provides a theoretical basis.
