冲击地压事件物理特征与几何特征的相关性与统一性

Relativity and unity of physical and geometrical characteristics of rockbursting events

提出并建立了冲击地压预测的“开采扰动势”模型 ,并在此基础上 ,对抚顺市老虎台煤矿冲击地压活动与人工开采扰动之间的关系进行了统计分析 .对冲击地压事件在时间、能量、空间上的分布规律、不同特征间相关规律及其统一性进行了探讨 .分析结果表明 ,冲击地压事件的能量特征、时间特征及空间特征之间不仅存在着密切的相关性 ,而且在一定条件下是相互统一的 .

A prediction model of mining disturbance potential (MDP) is proposed, based on MDP a statistic analysis is carried out on the relationship between rockbursting episodes and mining disturbances in Laohutai colliery in Fushun city. The bursting evidences are investigated on the time, energy and spatial distribution, as well as their relativities and unities. The study shows that there exist not only the relativity but also the unity among the characteristics of busting energy, time and spatial position, under some circumstances.
