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 coal mine engineering geological conditions in West Luan mine area of Shanxi as a background, the influence of five different factors on the coal pillars of the section was simulated with FLAC3D finite difference program. The orthogonal experiment scheme is established on the five factors of coal pillar width, coal pillar height, coal seam thickness, burial depth, and Platts hardness of fully mechanized coal caving face.
