摘要
为了完成对高变质煤层保护层保护效果的考察,将贵州五轮山煤矿中6-3突出煤层作为研究对象,同时将其下方的8#煤层作为保护层开采。通过监测保护层开采后被保护层的瓦残余斯压力以及残余瓦斯含量和顶、底板位移量,来进一步分析研究保护层开采对被保护层的保护效果。
In order to complete the inspection of the protective effect of the protective layer of the high metamorphic coal seam,takes 6-3 outburst coal seam in Wulunshan coal mine as the research object, and 8# coal seam below it is taken as the protective layer. The protective effect of the protective layer on the protective layer is further analyzed by monitoring the residual pressure of the residual layer of the protective layer after the protective layer and the residual gas content and the displacement of the roof and floor.
