摘    要:采场控顶设计是顶板管理的关键因素,而顶板岩层的运动规律是采场控顶设计的依据。按照复合顶板以“护”为主的原则,应用岩石破断分析系统(RFPA2D),通过数值计算得出了柳泉煤矿3煤工作面复合顶板离层、冒落、垮落的特征和规律,确定了工作面支柱的合理工作阻力和支护密度,最大限度地减少了压、漏、推冒顶事故的发生,取得了良好的经济效益。

关 键 词:控顶设计  支护参数  复合顶板  数值计算

Abstract:The roof control design in mined field is the key to roof control and the movement rule of roof terrane is the basis of the roof control design.According to the"maintaining"principle of combined roof,the characteristic and rule of roof separation,caving and collapse of the mined face in 3 Coal of Liuquan Colliery by numerical simulation with RFPA2D.Thus,the rational working resistance of supports and supporting spacing in mining face are confirmed,the roof fall accidents of pressing,caving,pushing reduce farthest and good economic benefit is obtained.
Keywords:roof control design  supporting parameters  combined roof  numerical simulation
