摘　　要：随着浅部采掘活动的结束,在有效保障现有采掘工程安全生产的前提下,以及对张双楼煤矿井下四灰涌水点封堵或减量治理可行性评价的基础上,利用现有水文地质参数并采用定流量注水承压完整井非稳定流模型对典型出水点不同减量治理后的水位恢复情况进行了预测,开展相应减量治理工程技术措施,在保障生产安全的前提下降低矿井排水费用。With the end of shallow mining activities, on the premise of effectively ensuring the safety production of existing mining projects, and on the basis of the feasibility evaluation of the plugging or reduction treatment of the four ash gushing points in Zhangshuanglou Coal Mine, the water level recovery of typical water outflow points after different reduction treatment is predicted by using the existing hydrogeological parameters and using the unsteady flow model of constant flow water injection pressure bearing completion well, and the corresponding technical measures of reduction treatment engineering are carried out, reduce the cost of mine drainage on the premise of ensuring production safety.
