以底板导水通道的形成机制为划分判据,将深部矿井底板突水模式划分为完整隔水岩层突水、隐伏构造突水和固有导水通道突水3大类;引用尖点突变模型到完整隔水岩层突水模式和固有导水通道突水模式中,构建了适用于隐伏构造突水模式的蝴蝶突变模型;基于突变模型平衡曲面的几何特性,分析了深井底板突水灾害的突变特征。研究表明:深部底板突水灾害在时间上具有突发性与滞后性;在空间上底板岩层灾变路径具有多模态性,隐伏构造突水模式和固有导水通道突水模式的突水位置具有规律性。
Based on the formation mechanism of the aqueduct channel, the water inrush pattern in the deep mine floor is divided into three categories: intact aquifer water inrush, concealed tectonic water inrush and inrush water inrush channel. By using cusp catastrophe model In the intact aquifer water-inrush mode and the intrusive aqueduct water inrush mode, a butterfly catastrophe model suitable for the buried structure water inrush pattern was constructed. Based on the geometric characteristics of the catastrophe model balanced surface, the catastrophic features of water inrush disaster in deep well floor . The research shows that the water inrush disaster in deep floor has the characteristics of suddenness and lag in time. The disastrous path of floor rock strata is multimodal in space, and the water inrush position of hidden structure water inrush mode and inrush water inrush channel has Regularity.
