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。
Based on the simulation principle, this paper selected similar materials selectively to simulate the mining conditions of two different mining schemes of the coal seams in Mencheng and observed and exposed the problems of the rock pressure and the limit of the hanging plate when mining. The pillars mining design provides an important parameter basis.
