According to the high mining cost,low mining efficiency,high accident risk and other problems in coal mine with coal and gas outburst in potential,the paper proposed that the features of mine should be correctly recognized in order to avoid wrong decision of mine investment. Before mining and excavation,regional comprehensi ve coal and gas outburst prevention and control measures should be conducted to effectively eliminate the outburst danger. During excavation period,the monitoring and co ntrol early warning technology of the coal and gas outburst danger should be conducted with special technical services and other measures as auxiliary in order to realize s afety and high efficient mining in the mine with coal and gas outburst in potential. The paper provided that study should be enhanced on outburst comprehensive function m . echanism and disaster occurrence mechanism,application of the surface engineering to realize the low cost rapid and accurate survey of deferent depth of each seam,differ ent sectional gas geological parameters,measuring technology of varied law and other aspects in order to further realize safety and high efficient mining with coal and gas outburst in potential.
