膨胀水泥封堵材料在庞庄煤矿的应用

Application of Expansive Cement Bloching Material in Pangzhuang Coal Mine

膨胀水泥材料是煤炭行业近年来研究应用的一种新技术,具有覆盖浮煤、填充孔洞、封堵裂隙等综合防灭火效果。为有效地解决黄泥封堵不严密等问题,庞庄煤矿通过采用该技术在条带、两道以及停采线等区域进行火灾防治,取得了较好的效果,可为开采自燃煤层矿井火灾预防与防治工作提供借鉴。

Expansive cement material is the new technology of coal industry, researched and applied in recent years. It has the comprehensive fire prevention effects of covering float coal, filling holes and plugging fracture. In or- der to solve the problems effectively, such as yellow mud cannot plug fracture tightly, Pangzhuang coal mine adopts this technology to prevent and control fire in the areas, such as the strip, two roadways and stop line, it achieves good results, provides a reference for fire prevention and control work of spontaneous combustion coal seam.
