【摘要】 非煤地下矿山采空区安全评估是一项有着重要理论意义和应用价值的研究课题。本文以吉林省延吉市和龙长仁金矿采空区来分析如何进行采空区安全评估和如何对采空区进行处理,主要完成了以下几个方面的工作:通过查阅大量文献资料,系统地总结了采空区安全的研究历史与现状,对其中的两类主要研究方法:唯象学研究方法和力学研究方法分别进行了详细总结和评述。之后对爆炸性物质、易燃性物质、危险性物质被定为重大危险源做了定性和定量的分析。尤其是矿山危险源有两个重要的方面,一方面采空区顶板大面积冒落,造成地表沉陷和开裂:另一方面在矿山开采过程中,采空区围岩受爆破震动等影响导致岩体裂隙发育,甚至贯通地表或连通老窿积水,发生突水事故。本文围绕着长仁金矿采空区的安全评估这一主线对长仁矿的金矿情况作了一个简单的介绍之后又对采空区的安全进行了这些方面的工作,对长仁金矿采空区从岩石力学、流体力学、弹性力学方面做了稳定性分析,对采空区灾害发生概率作了定性定量的分析,对受灾体社会财富作了价值核算,对采空区其他的危害也进行了分析,进而对长仁金矿采空区做了安全评估。论文最后对长仁金矿采空区在安全评估的基础上做了比较,根据矿山的基本情况,同时在安全经济的方面进行了优化,最终选择了上向进路充填法。这也是对采空区安全评估的一个重大应用,借助本文人们可以全面的而且深入的了解安全评估在采空区的研究和应用情况。更多还原

【Abstract】 Non-coal mine safety In coaf is a important theoretical significance and application value of research topics.In this paper,Yanji City,Jilin Province and Helongchangren Gold goaf to analyze how goaf safety assessment and how to deal with goaf,mainly to complete the following tasks:After referring to a large amount of literature materials,it summarizes the history and the present state of the research on the theory of the mining subsidence,expounds in detail about two main types of research methods:Statistic method,Mechanical study method,and also points out the disadvantages of them.After the explosive substances, flammable substances,dangerous substances classified as major hazard installations have done a qualitative and quantitative analysis.In particular,mine hazards,there are two important aspects,on the one hand goaf roof caving large area,resulting in surface subsidence and cracking;on the other hand,in the mining process,the mined-out area, such as rock by blasting vibration caused by rock body fracture,and even surface,or connected through the old water hole,water inrush incidents occurred.This article revolves around gold Changren goaf the main line of the safety assessment of long-jen mine made a payment in this case after a brief introduction on the safety of goaf conducted its work in these areas,the long gold-jen goaf rock mechanics,fluid mechanics,elasticity stability analysis done on goaf probability disasters were qualitative and quantitative analysis of the affected body made the value of wealth accounting for goaf other hazards also analyzed,and the long gold-jen goaf done a safety assessment.Finally the long-jen goaf gold in the security assessment made based on the comparison,according to the basic situation of the mine,while in the security aspects of the economy has been optimized,and ultimately chose to approach filling method.It is also a safety assessment goaf a major application,with this article can be a comprehensive and deeper understanding of the safety assessment of mined-out area in the research and application.更多还原
