摘 要:开采保护层一直都是防治煤炭瓦斯突出的重要的措施之一。从长远发展的角度来看也是最有效的手段之一。本文先对保护层开采的理论进行实际的分析,再对工作面保护范围内外的预测指标进行对比和分析,最终得出了保护层在开采之后,其工作面的预测指标均已降低到了临界值以下,并都取得了良好的防突效果。并从综合的角度来对煤矿近距离保护层的开采防突效果进行全面的考察。Mining protective layer has always been one of the important measures to prevent and control coal gas outburst. From the perspective of long-term development, it is also one of the most effective means. This paper first carries on the actual analysis to the theory of protective layer mining, and then compares and analyses the prediction indexes inside and outside the protective area of the working face. Finally, it is concluded that after the protective layer is exploited, the prediction indexes of the working face have been reduced to below the critical value, and good outburst prevention effect has been achieved. From a comprehensive point of view, the outburst prevention effect of protective layer mining in coal mine is comprehensively investigated.
