采用FLAC3D有限差分法分析软件模拟了白家庄煤矿上行开采的过程，通过改变层间岩层组合情况形成不同的数值模拟模型，计算分析上行开采前后层间岩层应力变化规律，在此基础上，进一步研究下、上煤层开采前后层间岩层的移动变形规律，最后通过层间岩层的力学关系及移动变形情况分析不同模型上行开采的可行性，与传统上行开采可行性理论判定结果及生产实际一致。
採用FLAC3D有限差分法分析軟件模擬瞭白傢莊煤礦上行開採的過程，通過改變層間巖層組閤情況形成不同的數值模擬模型，計算分析上行開採前後層間巖層應力變化規律，在此基礎上，進一步研究下、上煤層開採前後層間巖層的移動變形規律，最後通過層間巖層的力學關繫及移動變形情況分析不同模型上行開採的可行性，與傳統上行開採可行性理論判定結果及生產實際一緻。

In this paper,the process of upward mining in Baijiazhuang mine is analyzed by the simulation function in FLAC3D software,the varia-tion of rock pressure before and after upward mining is calculated and analyzed by means of numerical simulation model,and then the deformation and movement of middle strata before and after mining the upper and lower coal are further studied. Finally,the simulation results of studying the rock layer’s mechanical relationship and deformation condition is the same with actual mining.
