【摘要】 针对目前缺乏系统性评价冲击-突出复合动力灾害危险性的评价方法，基于复合动力灾害扰动响应失稳理论，综合考虑煤体应力、瓦斯压力、围岩结构、支护作用等，建立冲击-突出复合动力灾害危险性评估方法，并以某矿22240工作面为例进行现场应用。针对工作面的危险区域采用煤层注水进行解危，通过电荷监测验证解危效果。该方法能够量化评价工作面冲击-突出复合动力灾害危险性，为灾害防治提供有力依据。更多还原

【Abstract】 Aiming at the lack of a systematic risk assessment method for the combined dynamic disaster of rock burst and coal-gas outburst, based on the disturbance response instability theory of the complex dynamic disaster, the risk assessment method of rock burst and coal-gas outburst combined dynamic disaster was established by comprehensively considering the stress of coal body, gas pressure,surrounding rock structure and supporting role, and took the 22240 working face of a mine as an example for field application. Aiming at the dangerous area of the working face, coal seam water injection is used to solve the danger, and the effect is verified by charge monitoring. This method can quantitatively evaluate the risk of the combined dynamic disaster of rock burst and coal-gas outburst, and provide a strong basis for disaster prevention and control.更多还原
