摘　　要：为保证试采面的安全回采,研究巷柱式充填矿压规律,对王台铺煤矿充填试验面的矿压显现进行了实测研究。通过矿压数据分析可知,工作面开采期间,支巷顶板锚杆受力变化平稳,增幅较小;煤柱应力呈现增大—减小—增大的变化趋势,邻近支巷开采时,煤柱应力会迅速增加,支巷充填可以增强煤柱的承载能力;支巷中部离层值、顶板下沉值和两帮移近量均大于两端头。In order to ensure safe mining and research underground pressure of roadway stowing mining, underground pressure behavior was measured in stowing mining face of Wangtaipu Colliery. Analysis of underground pressure data showed that stress variation of roof anchored bolt in branch roadway was stable and its amplification was small during mining period. Stress of coal-pillar took on rise-fall-rise tendency. When mining was near branch roadway, coal-pillar stress rapidly rose, so stowing branch roadway could improve loading capacity of coal-pillar. Separation value at middle of branch roadway, and roof subsidence and two-side convergence value were larger than those at two ends.
