摘要
为了掌握宝鼎矿区水害的发生机理,根据宝鼎矿区矿井的充水因素,重点分析了矿区煤层顶板透水机理,建立上覆岩体渗流失稳判据的FLAC数学模型,并以透水因子作为判定保护煤柱是否发生透水的判定准则,结合室内渗流试验的数据,总结出宝鼎矿区煤层透水发生机理,用以指导安全生产。
In order to investigate the occurrence mechanism of Baoding Mining Area, according to the water filling factors of Baoding Mining Area, we focused on the analysis of the coal seam roof water inrush mechanism, and established FLAC mathematical model of overlying rock mass seepage instability criterion, and used water permeation factor as the criterion to determine whether the coal pillar was permeable. Combined with the data of indoor seepage test, we summed up the flooding occurrence mechanism of Baoding Mining area to guide the safety production.
