摘要
本文从顶煤冒放性影响因素出发，运用传统的岩石力学观点和现代分形力学理论，结合现场观测和相似模拟实验研究，辅之以正交有限元辅助试验，系统全面地研究了顶煤冒放性和诸影响因素的相关变化规律，并给出了诸影响因素的临界值范围。
tarting from the influence factors of top coal caving,this paper systematically and all sidey studies the tip coal cavibility anbd the correlation variation rule of various infouence factors,and gives the range of critical value by using traditional rock mechanicsand moderntheory of dividing form mechanics,combining field observation and similar simulation test,assisting aided test using orthogonal FEM.The practie and theoretical research indicate that theresearching the basic theory about topcoal cavibility and direceing the practice about top coal caving.
