摘要
结合多年矿井地质及防治水工作实践经验及研究成果,提出了"再沉积层"理论。分析了豫西三软不稳定特厚煤层开采后"再沉积层"形成的机理,并通过2次透水事故实例,分析了"再沉积层"对探放水工作的影响,为今后类似情况的探放水工作提供理论参考和经验借鉴。
On the basis of author＇s experiences of coal mine prevention-cure water practice for many years, referring to previous studies, firstly,the author put forward the ＂ anew sediment layer＂ theory,then analyzed the evolvement mechanism of ＂ anew sediment layer＂ after mining three-soft coal seam in the west of henan provience,at last,discussed the influnce of ＂anew sediment layer＂ to water dection and release. This can be used for reference to water detection and release work under analogue condition.
