煤炭开采灾害防控技术研究与思考

Study and consideration on the disaster prevention and control technology in deep coal mining

随着煤炭开采深度的增加,将面临高地压、高温、高瓦斯、岩石流变及动压扰动等越来越多的难题。基于诸多工程灾害发生和演化特征,通过分析这些灾害之间的关系和发生机理,构建了深部矿井灾害发生的路线及相互转化条件流程图;提出了提高"小结构"强度、"大、小结构"互补的能量控制和转移措施。针对具体工程技术条件,提出了全过程防控技术设计理念。

With the increase of coal mining depth,more and more problems will be confronted with,such as high pressure,high temperature,high gas,rock rheology and dynamic pressure disturbance. Based on the occurrence and evolution characteristics of many engineering disasters,the relationship and occurrence mechanism of these disasters was analyzed,the evolution laws and mutual transformation condition of disasters in deep mines were researched,and the energy control and transfer measures of'small structure'strength and'large and small structure'complementation were proposed. According to the specific engineering conditions,the design concept of the whole process prevention and control technology was put forward.
