【摘要】：为研究深部开采冲击地压、煤与瓦斯突出及其复合动力灾害的发生机制,并对其进行有效监测预警,运用事故调研、理论分析、工程实践等方法,分析了我国煤岩瓦斯动力灾害的影响因素,研究了其发生的统一机制和监测技术。结果表明:煤岩瓦斯动力灾害是冲击、突出共性因素和个性因素共同影响下的结果;根据灾害发生过程中能量释放的主体和形式,将煤岩瓦斯动力灾害分为冲击地压、煤与瓦斯突出、冲击-突出型复合动力灾害、突出-冲击型复合动力灾害4种类型;采用多层次统一监测模式,可对深井煤岩瓦斯动力灾害进行全方位连续的统一监测。最后将研究成果应用于煤矿现场实例,效果良好。
[Abstract]:In order to study the occurrence mechanism of rock burst, coal and gas outburst and its complex dynamic disasters in deep mining, and to monitor and warn them effectively, the methods of accident investigation, theoretical analysis, engineering practice and so on are used. The influencing factors of coal-rock gas dynamic disaster in China are analyzed, and the unified mechanism and monitoring technology are studied. The results show that the coal-rock gas dynamic disaster is the result of impact, prominent common factors and individual factors. According to the main body and form of energy release in the process of disaster, the dynamic disasters of coal and gas are divided into four types: impact ground pressure, coal and gas outburst, impact-outburst composite dynamic disaster and outburst combined dynamic disaster. The multi-level unified monitoring model can be used to monitor the coal and rock gas dynamic disasters in deep wells in all directions and continuously. Finally, the research results are applied to the coal mine field examples, and the results are satisfactory.
