煤岩复合模型冲击倾向的数值试验研究

Numerical experimentation study of impact trend of coal and rock compound model

本文从系统观点入手 ,建立了顶板 -煤层 -底板的煤岩复合模型 ,采用RFPA数值模拟软件进行了煤岩系统冲击倾向的数值试验 ,综合研究了顶、底板子系统及整体效应对冲击倾向的影响。结果表明 :煤岩系统与煤体的冲击倾向不同 ,煤岩系统冲击倾向随顶 (底 )板强度不同会发生明显的变化 。

By the way of systematic concept, the coal and rock compound model of roof-coal seam-floor is established. The impact trend of rock and coal system is simulated by RFPA (rock failure process analysis) numerical calculation software, and the influence which the roof and floor subsystem and the whole effect have on the impact trend have been studied. The results indicate that the coal and rock system differs greatly from the single coal in the impact trend, and there are obvious changes in the impact trend of coal and rock system when the strength of the roof and floor vary.
