摘要
本文依据模拟原理、针对性地选择了相似材料,模拟了门城煤柱两种不同开采方案的开采情况,观测与揭露了开采时呈现的矿压现象及悬板极限等问题。为该煤柱开采设计提供了重要的参数依据。
According to simulation principle, the simulating materials are chosen accordingly. The mining situation of two mining plans of Men Cheng-Pillors is simulated. The appearance of mine pressure shown by mining and ultimate of suspension board and other problems are observed and revealed. The basis of important parameters are provided for the pillar design.
