摘要
针对矿井顶板水害发生与防治过程中的环境时变性及模糊性问题,着重研究了兴隆庄煤矿3煤顶板中(粗)砂岩厚度、冲洗液最大消耗量、取芯率、平均孔隙度、断层密度5个因素的影响作用,同时参考了钻孔测井电性曲线的影响,然后利用信息拟合方法完成了顶板富水性分区,在此基础上进行了模糊预测,最后给出了应用实例。
This paper, aiming at the problems of the environmental time-variation and fuzziness in the process of occurrence and prevention of mine roof water inrush, emphasizes the study on the effect of such five factors as the thickness of medium （coarse） sandstone, maximum consumption of drilling fluid, coring rate, average porosity, fault density in the 3^rd coal seam roof of Xinglongzhuang Mine, especially references the influence of the electric property curve of logging in borehole, and then completes the zoning work of rich water-bearing roof strata by means of information fitting method. On above basis the fuzzy prediction is carried out and practical application is given.
