石头梅露天煤矿非工作帮煤炭资源开采实践

Mining practice of non working slope coal resources in Shitoumei Open-pit Coal Mine

为了提高石头梅一号露天煤矿非工作帮煤炭资源回采率、保障边坡稳定性,基于对采场补充勘查和非工作帮边坡稳定性分析研究,探讨了非工作帮煤炭资源开采措施。结果表明:通过采取削帮回采挂帮煤和内排压帮等措施,可消除边坡挂帮煤炭自燃的火灾事故隐患、增强边坡稳定性、提高煤炭资源回采率、降低投资成本、提高安全经济效益。

In order to improve the coal resources recovery rate of non working slope and ensure slope stability in Shitoumei No.1Open-pit Coal Mine,based on the supplementary exploration of the stope and the research and analysis of the slope stability of non working slope,the article discusses the mining measures of non working slope coal resources.The results show that by taking measures such as cutting and stoping,hanging coal and internal dumping,we eliminate the potential safety hazards of coal spontaneous combustion,enhance the stability of slope,improve the recovery rate of coal resources,reduce the investment cost,improve the safety and economic benefits.
