摘要
通过对彬长矿区其地质条件、水文地质条件、覆岩结构类型的分析、以及综放开采覆岩破坏导水裂隙带高度的预计,确定了洛河砂砾岩含水层下防水煤岩柱留设的原则,通过对保护水资源重要性与采煤条件的分析,指出了在洛河砂砾岩含水层下采煤是目前彬长矿区在理论上和技术上亟待解决的突出难题之一。
Analyzed the geological and hydrogeological conditions, covering rock structural types, predicted height of water conducted zone caused by fully mechanized caving method, defined safety pillar setting principle under the Luohe sandy conglomerate aquifer. Through analyzed the importance of water resource protection and mining condition pointed out mining under the aquifer is one of im- portant theoretical and technical problems demanding prompt solution in Binchang mining area.
