Abstract: Aiming at the problem of confined water and gas near X9 collapse column in W3309 working face with large mining
heigh of Sihe Coal Mine, the comprehensive method of "exploration, grouting, coring verification and extraction monitoring" was
adopted to reveal that the key point of water damage and gas control in collapse column of high outburst mine is 20 - 50 m below
the bottom floor near coal-rock interface.

 Key words: outburst mine; confined water; collapse column; grouting
