Stochastic finite element program of seepage and application in foresting water burst at coal seam roof
摘要
Abstract
Based on stochastic finite element theory and seepage mechanics, by means of deducting seepage stochastic FEM formulation, this study obtains stochastic seepage unit water matrix and introduces reliability calculation into random seepage of rained rock masses. According to seepage stochastic FEM formulation, a stochastic finite element program has been developed, which can be used to calculate rock stratum seepage. In addition, the program is used in the numeral calculation for the actual seepage at Ehuobulake mine. The results prove that this program well reflects the seepage properties of actual rock stratum. The protection of key stratum and waterproof stratum plays an important role in preventing water inrush from mine roof. The calculation results provide a rational suggestion for the exploitation at Ehuobulake mine, and also provide evidences for in-depth study on stochastic infinite element in terms of seepage.关键词
