摘要
为合理选用监测预警方法以便进行高效的冲击地压防治,通过工程与文献调研、理论分析、现场实践等方法,分析总结了我国煤矿冲击地压发生特征、影响因素、发生机理、监测预警手段等。结果表明：冲击地压大多发生在巷道,破坏范围一般为90～150 m,且矿震能量越大、距离巷道及采场越近,其诱冲可能性越高;冲击地压发生机理一般为静载应力集中和矿震动载扰动叠加作用的结果;冲击地压的监测预警主要从静载应力场和震动场两方面,单一监测方法难以实现对冲击地压的精确预测,而联合多种方法涉及震动场和应力场的多参量综合监测预警技术较为科学。
In order to rationaJly select the monitoring and early warning method to high efficiently prevention and control of the mine pressure bump ,with the engineering and literature investigation ,theoretical analysis, site practices and other method, the paper analyzed and summa- rized the features, influence factors, occurrence mechanism, monitoring warning means and others of the mine pressure bump occurred in Chi- na.The results showed that the most pressure bumps occurred in the mine roadway within a failure scope of 90~ 150 re.The higher mine seis- mic energy value and the distance more closed to the mine roadway and mining face, the higher possibility of the pressure bump occurred would be.The occurrence mechanism of the mine pressure bump would generally be the results of the statistic stress concentration and mine seismic dynamic interference superposition role.The monitoring early warning of the mine pressure bump would be mainly based on the two aspects of the statistic stress field and the seismic dynamic field, a single monitoring method could be hard to realize an accurate prediction of the mine pressure bump and Ihe combined multi methods and the multi parameter comprehensive monitoring early warning technology of the seismic dynamic field and stress field would be scientific.
