摘要:
确定断裂导水裂缝带的最大高度是保水开采的关键技术。结合陕北榆神府矿区地质开采条件,应用关键层理论,通过关键层挠度计算,分析关键层结构稳定性和对关键层上位隔水层破坏强度,给出关键层在不同位置影响导水裂缝带最大高度的广义损伤因子,建立了保水开采识别系统。工程实例表明:应用保水开采识别系统判定的断裂导水裂缝带高度与实际相接近,并能够很好地解释覆岩发生破坏的特征与规律,对实现保水开采具有一定的应用和指导价值。
Abstract:
Key technology on water-preserved-mining is confirming most altitude on fracture zone, paper combines geology mining condition of shaanbei-yushen mining area to deduces broad sense damage factor on fracture zone by key stratum theory, key stratum flexibility calculation, key stratum structure stability analysis and epigyny separation water layer destroy intension on key stratum. Paper bases this factor on studying water-preserved-mining discriminating system that more forecasts most altitude on fracture zone, thereby realizes water-preserved-mining. Discriminating system has been proved by engineering examples, which forecasts most altitude on fracture zone approach to fact, and logically explain the damage character and rule on overturn, and has definite meaning to coach locale.
