1) water factor
水因数
2) rain factor
降水因数
3) water-inrush-factor
突水因数
1.
Based on the column of rock mass in A Coal Mine,the distributions of stress in mining floors are simulated by using the numerical testing machine (RFPA) at the moment when longwall mining is pushed on to 25 meters and 50 meters respectively; and the water-inrush-factors are calculated on the basis of the relationship between permeability parameters and strain.
根据A矿的岩层柱状图,运用RFPA2D软件计算了采场推进到25m和50m时底板岩层的应变分布,且利用渗透特性与应变之间的关系,计算了相应的底板突水因数。
