摘要
充填开采是煤矿保水开采的重要技术,充填材料的强度决定着充填尺寸和充填效果,也决定着充填工艺和充填成本,是充填开采的关键因素。为此,分析了煤矿充填开采充填材料的研究和应用进展,总结了膏体材料的力学特点和强度性能,分析了充填开采对充填材料早期强度和后期强度的要求,提出了确定充填材料强度的方法。
Stowing mining is an important technology for protecting water resource.Stowing material strength determines stowing dimension,stowing effect,stowing technique and stowing cost,so it is the key to stowing mining.Stowing material research and application status in coal mine was analyzed and mechanical characteristic and strength of paste material was concluded.Requirement for earlier strength and later strength of stowing material was analyzed and method of confirming stowing material strength was put forward.
