摘要: 老虎台矿开采煤层最大厚度130 m,采区大型断裂带14条,开采历史80余年,水文地质条件复杂。应用Midas-GTS有限元分析软件及实际工程资料分析了老虎台矿开采的突水危险性,详细分析了突水水源及突水通道。突水水源包括第四纪冲积层含水层、地表水、移动盆地中积水、断层水及老采区水;突水通道主要是受开采影响形成的导水裂隙带及活化的断层。通过分析得出现今73003#及73004#开采工作面突水危险性很高,须采取必要措施方可继续开采。

关键词: 特厚煤层, 综放开采, 导水裂隙带, 突水危险性

Abstract: With the largest coal seam thickness of 130 m,Laohutai coal mine has 14 large-scale fault zones and mining history more than eighty years in,so the hydrological condition is very complex.The water inrush risk of Laohutai coal mine are analyzed by Midas-GTS software and engineering data,and the detailed analysis on water inrush source and channel is made.The water inrush source includes:aquifer of quaternary alluvium,surface water,water accumulation in movement basin,water in the faults and old mining area; the channel are mainly water flowing fractured zone and activated faults induced by mining.The conclusion is that the current 73003# and 73004# working face have high risk of water inrush,which are required to take the necessary measures for continuing mining.

Key words: Superhigh seam, Fully mechanized caving, Water flowing fractured zone, Water inrush risk
