摘要
本文根据底板突水实例的统计资料，研究了突水灾害的空间分布规律；通过综合分析煤层底板内应力测试三维有限元电算及相似材料模拟结果探讨了底板突水灾害地下三维空间分布规律形成的原因。
In this paper, based on the statistical data of the practical water irruptions, the three dimensional dispersion feature of water irruption is researched. By the synthetical analysis of the study results of stress testing in seam floor, finite element computation of three dimension and model experiment of similars material, the three dimensional dispersion feature of water irruption in seam floor is discussed. This can provide reference to go deep into the study on the prevention and cure of water irruption.
