目前,塔斯塔戈尔铁矿的开采深度已达700～900米,随着开采深度的加大,冲击地压显现的频度和能量在不断增大。现在已记录到的约有340次动态显现,其中50多次是微冲击,乃属冲击地压之列。近年来,该矿发生过几次大的冲击地压,导致巷道的大面积破坏和投入大量资金进行修复。 At present, the mining depth of the Tastaguer iron mine has reached 700-900 meters. As mining depth increases, the frequency and energy of rock burst have been increasing. Now about 340 recorded dynamic show, of which more than 50 are micro-impact, is the impact of pressure to the column. In recent years, there have been several major rockburst in the mine, resulting in large-scale destruction of the roadway and huge investment in repairs.
