摘要
本文分析了长壁工作面沿空巷道底臌的主要原因，从刚塑性滑移场理论出发，提出用巷道角锚杆防治沿空巷道底臌的方法。并提出了密度计算公式和锚杆长度的确定原则，在实际应用中取得了良好的效果，在锚杆支护理论方面和现场生产应用方面均有实际意义。
This paper analyses the main reasons that causes floor lift of longwall face goaf-sidc roadway.According to clastoplastic slip fleld theory,puts forward goaf-sidc road floor lift con-trol way by using corncr bolt. Raises the determining principle of density calculating formula and bolt Iength. Good effect has been obtaincd in practical applications, This paper has actual signifi-cance in bolting theocy and its uses.
