【摘要】 中国是世界上鲜有的以煤炭作为主要能源的国家之一，近年已超过了世界总产量的三分之一，与煤炭生产相关的生产事故十分突出。随着煤炭资源绿色开采、高效开采理念的提出和国产设备和放顶煤开采技术水平的提高，露井联采方式日益成为目前浅埋煤层高产、高效矿井的主要开采方式。露井联采模式下，露天与井工之间的相互扰动，对露天边帮的破坏程度，范围等具有很大的影响。国内外露井联采的矿山较多，露井联采在非煤矿山开采已比较成熟，但煤矿采用露井联采的矿山较少。露井联采模式对采动、边坡稳定的影响在水利工程和隧道工程中应用和研究较多，针对煤矿研究较少。本文以露井联采条件下采动边坡稳定性为研究。采用现场勘察、室内试验、理论分析和数值模拟相结合的研究方法，建立基于塑性极限理论的采动边坡稳定性评价方法。结合中煤露天开采的安太堡南帮典型工程进行重点研究。研究成果对露井联采矿区的安全生产和类似工程，具有十分重要的理论意义和工程实用价值。更多还原

【Abstract】 China is one of the countries in the world which sees coal as the main energy. Its coalproduction has exceeded one third of the world’s and the industrial accident related to thecoal industry is highlighted. With the idea of green mining of coal resources and efficientmining put forward, open-pit and underground combined mining increasingly becomes themain way of exploitation of the high yield and efficient mine which aims at the shallowcoal seam. In the mode of open-pit and underground combined mining, the mutualinterface of open-pit and underground has a big impact on the degree and the range ofdisruption of open-pit slope.There are more mines which use open-pit and underground combined mining at homeand abroad, and the application of open-pit and underground combined mining in theexploitation of non-coal mine is relatively mature, while the coal mines which use open-pitand underground combined mining is less. The application and study of influence ofopen-pit and underground combined mining mode on mining disturbance is more in waterconservancy projects and tunnel project, while the study related to coal mines is relativelyless. This article studys the mining disturbance and slope stability in the condition ofopen-pit and underground combined mining. The research method which combines thefield investigation, laboratory experiment, theoretical analysis and numerical simulation isadopted, the evaluation methods of mining disturbance and slope stability which is basedon the plastic limit theory is established. This article focused on the evaluation of miningdisturbance and slope stability taking the southern slope of Antaibao mine as an example.Research results have the very important theoretical significance and practical value inengineering for safety production of open-pit and underground combined mining ore locus.更多还原
