罗克休泡沫处理大冒高巷道顶板事故

Handling Roof Disaster with Large Falling Height in Roadway with Luokexiu Foam

为了及时有效地处理复杂地质条件下巷道的冒顶事故,确保不影响矿井正常生产和巷道外观形状,结合工程实例,介绍利用罗克休泡沫材料的高速成形、高膨胀率,实现了大冒高巷道冒顶事故分3次快速充填的施工工艺和过程,并对罗克休泡沫充填冒顶区的注意事项进行了分析。

For timely and effectively dealing with roof falling disaster and ensuring regular mining and keeping roadway shape, this paper introduced fast stowing technique in roadway with large falling height at 3 times by applying high - speed forming and high expansivity of luokexiu foam. It also analyzed matters needing attention in stowing falling area with luokexiu foam.
