| Abstract: | The comprehensive management mechanism,namely coal seam mining without protective layer,gas drainage through boreholes,drilling in different sections with interval space,deep-hole pre-splitting blasting technique as well as coal and gas outburst periodic safety-evaluation,was used to solve the technological problem of coal and gas outburst existed on No.E9-20180 fully-mechanized working face in No.10 mine of Pingdingshan Coal Mining Company Ltd..The results indicated that gas content in coal mass reduced from 8~13 m3/t to 3.2932 m3/t,avoiding the accident of coal and gas outburst and ensuring the safe production. |
