摘要
矿山的安全生产对国家的形象非常敏感,也是受到国内外关注的大事,金属非金属矿山安全形势不容乐观,矿山事故频发。我国露天开采的产量所占的比重相当大,其中有近40%露天边坡不同程度存在边坡稳定性问题,金属非金属露天矿山大中型边坡灾害较为严重。我国金属非金属露天矿山大中型边坡高度大,边坡工程地质条件复杂,随着采深的加大,边坡稳定问题有日趋严重的趋势,边坡滑坡等灾害已经成为危及矿山安全生产和人民生命财产安全的重大灾害。通过调查数据的归纳和总结,分析我国金属非金属露天矿山大中型边坡灾害现状,并提出具体的对策。
Mine safety production is sensitive to the national image and is an important issue gaining attention both in and outside China. The safety situation in both metal and nonmetal mines is not optismetic as mine accidents frequently occur. Open-pit mining production occupies a large proportion in mining in China and nearly 40% of the open-pit slopes have the problem of instability, with the more serious disasters occurring in medium and large size open-pit slopes in both metal and non-metal mines. Such slopes are characterized by great slope height and complex engineering geological conditions. With the increase of the mining depth, the slope stability tends to be increasingly more serious and the disasters such as slope sliding have become the major disastors endangering the safety mining and the security of people＇s life and property. Based on the summary of the survey data, the status quo of the medium and large size open-pit slopes in both metal and non-metal mines in China are analyzed and the specific countermeasures are proposed.
