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。
In order to study the mechanism of rock burst, coal and gas outburst and its composite dynamic disasters in deep mining, and carry out effective monitoring and early warning of such disasters, the accident investigation, theoretical analysis and engineering practice are used to analyze the mechanism of gas dynamic disasters in China Influencing factors, studied its unified mechanism and monitoring techniques. The results show that the coal mine gas dynamic disasters are the result of common impact and common factor and individual factor. According to the main body and form of energy release during the disaster, the coal mine gas dynamic disasters can be divided into rock burst, coal and gas Highlighting, impact-highlighting composite dynamic disasters, highlighting-impacting composite dynamic disasters. The multi-level unified monitoring model can be used to monitor the coal mine gas dynamic disasters in all directions continuously and uniformly. Finally, the research results are applied to coal mine site examples, the effect is good.
