摘　　要：以岱庄煤矿6351膏体充填工作面为工程背景,基于材料力学相关理论建立梁式力学模型,推导出膏体充填开采条件下安全系数计算公式,通过相似模拟,分析了膏体充填工作面顶、底板受力及移动变形规律。研究成果对岱庄煤矿下组煤安全高效回采及其它他类似地质条件下的煤炭安全回采具有重要的指导意义。Taking the 6351 paste filling face of Daizhuang Coal Mine as the engineering background, based on the related theory of material mechanics, the beam mechanical model was established, and the calculation formula of safety factor under the condition of paste filling mining was deduced. Through the similar simulation, the law of stress and movement deformation of the roof and floor of paste filling face was analyzed. It is of great significance to guide the safe and efficient mining of lower group coal and other similar geological conditions.
