摘 要:郑煤电告成煤矿25采区泵房围岩较软,支护易出现扭曲变形和滑移。经分析变形破坏特征,实施U型钢棚+锚索+注浆耦合支护+辅助控底支护,取得良好支护效果。为类似条件矿井深部的泵房支护提供有益经验。The surrounding strata of pump-room in 25th district of Gaocheng mine are weak, the support in which is easily to be twisted and slipped. After seriously analyzing the features of supporting damage, takes up with combined supporting of U-steel ladder-shaped support, bolting shotcreting with wire and grouting, as well as assistant measures for controlling floor experimentces for pump-room supporting A satisfied supporting effect is obtained, which provides beneficial in mines of similar conditions.
