摘要
以山西潞安西部矿区煤矿工程地质条件为背景,用FLAC3D有限差分程序计算模拟5种不同因素对区段煤柱的影响。对综放工作面煤柱宽度、煤柱高度、煤层厚度、埋藏深度、煤层普氏硬度系数5个因素建立正交试验方案。
Taking the geological and mining technical conditions in the west region of Lu'an colliery as example,applying FLAC3 D,it researched the influence of five different elements for coal pillars.Establishing an orthogonal pilot program in five factors:fully mechanized caving face pillar width,pillar height,seam thickness,depth of burial,platts coal hardness.
