摘要
常用的煤柱留设公式——A.H.威尔逊公式,因其假设条件致使实际工程应用中误差较大,为此,通过数值模拟软件对其进行了改进,并对比了不同锚杆支护条件下巷道围岩位移量,提出了一般条件下煤柱的留设公式。
In order to reduce error of commonly used A.H.Wilson coal pillar design formula caused by assumed condition,the paper improved it by numerical simulation and compared roadway displacement under different anchored bolt supporting conditions.A coal pillar design formula for normal condition was put forward.
