综采工作面顶板充填技术研究与应用

Research and Application of Roof Filling Technology for Fully-mechanized Mining Face

梅花井煤矿1104203综采工作面回采范围存在一条M502向斜轴,回采期间受向斜影响,煤壁片帮严重、顶板破碎,经常发生冒顶事故,用罗克休E对冒顶区和破碎区进行充填,一定程度上终止了岩石的塌落,封堵围岩裂隙,对顶板管理起到了一定的作用。

Within the mining range of the fully-mechanized mining face 1104203 of Meihuajing Coal Mine,there is a synclinal axis M502 where,impacted by the syncline,there are serious rib spalling,broken roof and roof collapse during the mining.In view of this,Rocsil Foam E is used to fill the collapsed roof and broken areas to stop rock collapse and block off wall rock fissures to a certain degree,playing a certain role in the roof management.
