露天转地下覆盖层理论研究与实践的进展及趋势

Progress and Trend of the Theoretical Research and Practice of the Covering Layers of Open-pit to Underground

露天转地下覆盖层作为地下开采的保护设施,具有防止冲击地压、形成挤压爆破和端部放矿条件、阻滞水、减少漏风、防寒保暖、预防泥石流等作用。详细讨论了国内外研究机构在露天转地下结构、运移规律、安全作用机理等方面的最新研究成果,介绍了国内矿山露天转地下覆盖层形成应用过程中的成功经验。最后,总结了未来露天转地下覆盖层研究的方向和趋势。

As the protection facilities of underground mining,the covering layers of Open-pit to un-derground has the effects of prevention of impact pressure,forming condition of extrusion blasting and side ore drawing,stopping,retention of water,reduction of the air leakage,prevention of cold and keep-ing warm,prevention of mudslides.The latest research results of the structures,migration regularities and security mechanism of Open-pit to underground obtained by some research institutions in domestic and overseas are analyzed in detail,the successful experiences of the formation and application of the covering layers of open-pit to underground are introduced.Based on above analysis,the direction and trend of the covering layers of open-pit to underground in the future are summarized.
