摘　　要：通过对西湾露天煤矿非工作帮进行物探研究分析,结合现场涌水点分布及涌水量情况,确定非工作帮保安煤柱回收范围。在确保烧变岩孔洞裂隙含水层不导通的情况下,保证安全生产及边坡稳定,制定了合理的非工作帮煤炭资源回采方案及安全技术措施。回采方案不仅有效的回收了非工作帮保安煤柱,提高了资源回采率,同时为企业创造了良好的经济效益。Through the geophysical research and analysis of the non-working slope of Xiwan surface coal mine,combined with the distribution of on-site gushing point and water inflow,the non-working slope security coal pillar recovery scope is determined.Under the condition of the fractured aquifer of the burnt rock hole is not conductive,a reasonable non-working coal mining recovery plan and safety technical measures were formulated to ensure safe production and slope stability.recovery scheme not only recycled coal pillars beneath non-working slope security and improved resource recovery rate,but also bridged great economic benefits for enterprises.
