Research on the Effectiveness of Mining Upper Protective Coal Seam for Preventing and Controlling Coal and Gas Outburst and Gas Emission

摘要：

The method of mining protective layers is an effective means to prevent coal and methane outbursts. According to the theories of mining upper protective layer, it synthetically analyses the protected effectiveness by means of examining several parameters, finally it obtains the specific indexes and effectiveness of mining upper protective layer. The research has really applied worth and will give beneficial references to mining area with analogous conditions.
