胶体泥浆隔离带防灭火技术在7513综放面邻近采空区的应用

Application of Colloid Sludge Isolation Technique in Preventing and Extinguishing the Fire in Adjacent Goaf of 7513 Fully Mechanized Coal Face

在实施无煤柱 (或小煤柱 )开采的矿井中 ,防治邻近采空区煤炭自燃发火的传统措施很费事 ,而在姚桥煤矿 75 13综放面应用的胶体泥浆隔离带防灭火技术 ,具有用料省、施工强度低、防灭火效果显著等特点 ,是一种极具推广应用前景的防灭火创新技术。

In the coal mining without pillar or with small pillars, it is very difficult to prevent and extinguish the spontaneous combustion of coal in adjacent goaf with traditional measures. However, by applying the colloid sludge isolation techniques, the result showed very efficient, material saving, and easy to construct. It has been proved in 7513 fully mechanized coal face of Yaoqiao coal mine. It is a brand new technique, and worthy to be further applied.
