摘　　要：通过理论分析与现场试验研究,丰富和发展了保护层开采的基本理论,建立了保护层开采效果考察及评价体系,确定出了合理超前距、走向、倾向卸压保护角等技术参数。In this paper,the au-thor enriched and expanded the basic theory of extraction of pro-tective seams,set up the system for i nvestigating and evaluating the extraction effect of protective seams and determined the tech-nological parameters including rational advanced distance,strike,dip and protective angle for pressur e relief.

关 键 词：煤层 多重保护层开采 煤突出 瓦斯突出 除突技术 防突效果
