摘要
随着矿井开采深度的增加,煤与瓦斯突出愈加严重,保护层开采作为防治煤与瓦斯突出最有效、最经济的一种方法而成为研究热点.通过国内外相关文献的整理和分析,以保护层开采判别准则为基础,结合保护层开采后的理论分析,文章分上保护层和下保护层两类,对相似材料模拟、数值模拟和现场考察来确定保护范围的研究现状进行了总结,分析存在的问题,为保护层开采的进一步研究提供参考.
With the increasing depth of mining,the outburst of coal and gas has become even more serious.As the most effective and economical way of prevention and treatment of coal and gas outburst,protective layer mining has become a study object for scholars and experts. By sorting out and analyzing relevant literature at home and abroad,and aiming to protect layer mining criterion combined with a protective layer after mining,this paper,based on the theoretical analysis points on both the protective layer and the protective layer under. The scope of the research is summarized by similar material simulation,numerical simulation and on- site visits.This paper also analyzes the existing problems,pointing out the direction for future development.
