Abstract: Abstract:liziya South Second mine first mining face inclination is 48°,soft roof and floor rock,coal has outburst,fast, how to cutting through fast a safe and economical open cut,control a good roof is a major problem.After many discussions,uses the anti-well drill through the construction,using limit equilibrium method for support designing.Mine pressure monitoring results show that the construction technology and support is feasible,the construction can be realized quickly and safely, and the open cut distortion has been effectively controlled.

Key words: Keywords: Anti-driller law, large section open - cut, steep seam, combined support, tunneling
