断层突水具有较强的隐敝性和难确定性，严重威胁着煤矿的安全生产。项目采用理论分析、室内试验、数值模拟、相似模拟和现场监测相结合的方法，对深部承压水上采动底板断层突水过程中的应力、位移、裂隙、渗流、温度等多场前兆信息的演化规律、耦合特性及影响因素进行研究。通过制备大尺寸含矩形空洞和单一裂隙（类）岩石试样，研究水-力耦合下矩形空洞突水过程中单一裂隙围岩应力、位移、裂隙、渗流、温度等多场前兆信息的演化规律与影响因素；利用可视化流固耦合相似模拟试验，再现工作面推进过程中承压水对断层围岩裂隙渗透、冲刷以及形成通道等突水过程中的多场前兆信息。在此基础上，揭示深部底板断层突水多场前兆信息的判识性、定量性与敏感度，阐明多场前兆信息的临突阈值与判识准则及其权重。依据多场前兆信息在突水演化过程中的先后、作用及其权重的不同，构建深部底板断层突水多场前兆信息逐次监测预警方法，以期实现深部含断层工作面的安全带压开采。

Water-inrush caused by the fault in coal mine has strong hidden and uncertainty, which seriously threaten to the safety production of coal mine. The evolution law, coupling characteristics and influencing factors of the multi-field precursory information of stress, displacement, fracture, seepage and temperature in the water-inrush process of floor fault in the deep of coal mines above confined aquifers are studied by the ways of theoretical analysis, laboratory test, numerical simulation, similar simulation and on-site monitoring. By preparing the large-size rock samples or rock-like samples containing rectangular void and single fissure, the evolution law and influencing factors of the multi-field precursory information of stress, displacement, fracture, seepage and temperature of the single fissure surrounding rock in the water-inrush process of the rectangular void under the condition of hydro-mechanical coupling are studied. Using the visual fluid-solid coupling similar simulation test, the multi-field precursory information in the water-inrush process of the infiltration and erosion of confined water on the fault surrounding rock fissure and forming the water-inrush channel are reappeared. The results can reveal the recognition, quantification and sensitivity of the multi-field precursory information in the floor fault water-inrush in the deep of coal mines, and clarify the threshold, identification criterion and weight of the monitoring-warning of the multi-field precursory information. According to the sequence, role and weight of the multi-field precursory information in the water-inrush evolution process of floor fault, a successive monitoring-warning method of the multi-field precursory information is presented to monitor and warn the floor fault water-inrush in the deep of coal mines, which can realize the safety mining of coal seam with fault in the deep of coal mines above confined aquifers.
