新型复合浆体材料特性研究

针对煤矿现有传统喷涂堵漏风材料的缺点,研制出了一种以粘土、水泥、添加剂和玻璃纤维为基料的新型复合浆体材料。通过理论实验分析,该复合浆体材料具有较好的抗压和抗弯强度,能够承受一定程度地应力等导致的巷道变形;具有良好的抗氧化性能,能够防止因风化等因素导致的喷涂材料脱落;具有很强的抗渗性,能够达到堵漏风的要求。通过复合浆体材料在白芨沟煤矿的应用实验,巷道漏风量减少了83%。

Study on Property of A New Composite Slurry Material

Considering the shortcomings of the traditional spraying plugging material in the coal mine,a new composite slurry material containing clay,cement,fiber glass and some additives was developed.Through the theoretical and experiment analysis,the new composite slurry material,with good compressive and flexural strength,can withstand a certain degree of stress caused by roadway deformation.It has good oxidation resistance property to prevent the spray material off caused by weathering and other factors.With strong impermeability,the new material can achieve the requirements of plugging wind.Through the experiments of the new composite slurry material in Baijigou coal mine,the air leakage in roadway reduced by 83%.
