为提升煤矿断层水害感知水平,提出一种以断层活化演变机制和关键控制因素识别的断层突水阶段化感知方法,通过断层突水演化过程相似模拟试验研究工作面底板与断层破坏的演化特征,以底板破坏带应力、断层裂隙带应力、导水通道内水压等为阶段监测参数,揭示各监测参数与涌水量变化的阶段特征;结合灰色关联性分析法,判定断层突水阶段转化的关键控制因素,进而根据断层突水分析与研究过程,提出断层突水阶段化感知方法.结果表明:底板破坏带、断层裂隙带的应力,导水通道内的水压等监测参数的数值变化特征在断层活化突水过程中呈现出明显的阶段特征,控制因素与涌水量的灰色关联度排序为:底板破坏带应力＞断层裂隙带应力＞导水通道水压,通过对关键控制因素的识别,可实现断层突水阶段的感知,揭示基于灰色关联分析的感知方法在原理上具备可行性.
Staged sensing method of fault sudden water based on gray correlation analysis
In order to improve the perception level of fault water damage in coal mine,a fault water inrush stage sensing method based on fault activation evolution mechanism and key control factors was proposed.The evolution characteristics of working face floor and fault failure were studied through similar simulation tests of fault water inrush evolution process.The stage characteristics of monitoring parameters and the change of water inflow were revealed by taking the stress in the failure zone of floor,the stress in the fracture zone of fault and the water pressure in the water channel as the stage monitoring parameters.The key controlling factors of water inrush phase transformation were determined by grey correlation analysis method.Then,according to the fault water inrush analysis and research process,the fault water inrush stage perception method was proposed.The study determines that the numerical variation characteristics of monitoring parameters such as stress of floor failure zone,fault fracture zone and water pressure in water channel show obvious stage characteristics during fault activation water inrush.The order of grey correlation degree between control factors and water inflow is as follows:stress in floor failure zone＞stress in fault fracture zone＞water pressure in water channel,through identification of key control factors.Through the identification of key control factors,the perception of fault water inrush stage can be realized,and the perception method based on grey correlation analysis is feasible in principle.
