煤矿进入深部开采后,煤岩体物性、应力、瓦斯等因素发生显著改变,开采覆岩扰动范围及动静载荷显著增大,矿井群联动致灾效应与大型地质体控制效应显现,冲击地压、煤与瓦斯突出灾害并存甚至相互转化,煤矿深部开采煤岩动力灾害防控已成为当前亟待解决的问题。针对我国煤矿深部煤岩动力灾害孕灾条件复杂且尚不清楚,相互转化机制不清,快速探测手段、科学有效的防控技术与装备缺乏的现状,凝练了深部开采煤岩动力灾害防控的关键科学技术问题,提出了多尺度分源防控深部煤岩动力灾害的思想,确定了深部开采煤岩动力灾害防控技术的攻关方向,构建了煤矿深部开采煤岩动力灾害多尺度分源防控理论与技术架构,最终将形成我国煤矿深部开采煤岩动力灾害多尺度分源防控理论与技术体系,为我国煤矿深部开采冲击地压、煤与瓦斯突出和复合煤岩动力灾害有效防控提供理论支撑和技术途径。

The deep mining of coal mines leads to some significant changes in the physical properties of coal and rock, stress environment and gas occurrence law. The perturbed range of overlying rock and level of dynamic-static load have also increased significantly. In addition,the disaster effect caused by the linkage of mine groups and the control effect of large geological bodies appear in deep mining. The same disaster effect with the coexistence and conversion of rock burst and coal & gas outburst occurs. Therefore,above characteristics make the prevention and control of dynamic dis- aster in deep coal mines become a problem to be solved urgently. Considering the situation that the conditions of disas- ter breeding and mutual transformation mechanism are complex and still unclear,the quick detection method,preven- tion-control technology and equipment are still lacking,in this paper,the key scientific and technical problems of pre- vention-control for dynamic disaster in deep mining are condensed,the thought of prevention and control with different sources in multi-scales for coal and rock dynamic disasters in deep mining is proposed,the research direction of pre- vention and control technology for dynamic disaster in deep mining is determined,and the theory and technical frame- work of prevention and control with different sources in multi-scales for coal and rock dynamic disasters in deep mining are established. Based on the above achievements,the theory and technology system of prevention and control with dif- ferent sources in multi-scales for coal and rock dynamic disasters in deep mining are formed successfully,which can provide a theoretical and technical support for the prevention and control of rock burst,the outburst of coal and gas or compound dynamic disaster in deep mining of coal mines in China.
