| 摘 要： | 为了给采空区瓦斯抽放高位钻孔的设计提供依据,通过物理相似模拟实验,研究分析了东欢坨矿3088工作面覆岩破坏规律。通过研究发现,由于工作面上覆岩层中的灰白色细砂岩具有遇水软化的特性,从而使得采场上覆岩层纵向裂隙在该岩层呈现周期性贯穿-非贯穿的规律,而灰白色细砂岩的这一周期性破坏规律对瓦斯升浮具有重要影响,为达到良好的瓦斯抽放效果,给出了采场抽放钻孔进行高低搭配设计的建议。

| Abstract: | In order to offer references for design of gob gas drainage with high-level borehole,Simulation experiment is made to study the law of overlying strata fall for 3088 working face in Donghuantuo Mining.Since off-white fine sandstone with the character of softening when meeting water,the character makes longitudinal fracture of off-white fine sandstone in overlying strata present the law of periodical penetration-no penetration by studying.The law of periodicity has important influence on float upward of gas.... |
