在揭开急倾斜突出危险煤层时,利用苏联乌克兰科学院冶金矿山技术研究所研制的尿素甲醛树脂凝胶溶液的物理——化学方法(ФХО)预防煤和瓦斯突出(其中包括,在形成煤层结构急剧变化的地质破碎影响带内),突出危险煤层结构最大的变化是出现在断层地区附近或直接出现在褶曲破碎地带(在煤层从背斜褶曲轴向下倾的变化区域),同时,众所周知。在断层侧翼上、单褶曲顶点、急倾背斜的拱顶和一切向斜轴部的都显现出压实的趋势。但是,随着煤压实的同时,在其他煤层或者夹层中可以显现出煤体松动现象。
In the process of uncovering the steeply inclined and prominent dangerous seam, the physical-chemical method (ФХО) of urea formaldehyde resin gel solution developed by the Institute of Metals and Minerals Technology of the Soviet Union Ukrainian Academy of Sciences was used to prevent coal and gas outburst (including, The most significant change in the structure of a coal seam that is in danger of alteration occurs in the vicinity of the fault zone or directly in the fold-breaking zone where the coal seam descends axially downward from the fold of the anticline, and it is well known. On the fault flanks, the single fold tip, the steeply inclined ramp’s dome, and all the syncline axes show a tendency to compact. However, as the coal is compacted, coal looseness can be observed in other coal layers or intercalations.
