【摘要】 用尖点突变模型对坚硬顶板下煤柱岩爆非稳定机制的讨论，给出了岩爆发生准则，岩爆时的顶板突跳和能量释放量，讨论了影响岩爆的因素及影响程度，并以此为基础讨论了岩爆发生的前兆规律与过程，提出了可监测的前兆信息．这种既研究准则、又研究前兆与过程的方法，是防治岩爆的更为实际和有效的途径。更多还原

【Abstract】 The unstable mechanism of bump of the coal pillar under hard rocks is discussed by using a cusp catastrophic model. The criterion of rock burst occurrence,and the quantity of roof jump and energy liberated are also discussed. The factors affecting rock burst and degree of influence are discussed.Based on these, the forewarning rule and process are addressed, and the forewarning information which can be monitored can also be proposed- This is a practical and effective approach for investigate the criterion and forewarning signs and also for prevention of rock bump.更多还原
