【摘要】:平朔东露天煤矿开采境界范围内有众多小煤矿,由于这些小煤矿长期的无序开采、无充填开采、采富弃贫等现象,造成了平朔东露天煤矿开采境界内现存在大量的地下采空区,而这些采空区大多数都没有位置、尺寸等具体资料,给露天煤矿的安全高效生产带来很大的隐患。论文以平朔东露天煤矿采空区为研究对象,对采空区的探测、采空区上覆岩层安全厚度的计算以及采空区处理和采矿一体化展开研究。论文首先分析采空区探测常用方法的工作原理、优缺点以及适用范围,结合平朔东露天煤矿的实际情况,得出平朔东露天矿采空区探测工艺。论文通过分析相关资料,整理出采空区上覆岩层安全厚度计算所需计算参数,在此基础上,通过多种不同的理论方法和数值模拟方法,综合分析得出采空区上覆岩层安全厚度的合理值。论文最后通过分析露天煤矿开采境界内采空区独有的特点,结合露天煤矿生产实际,得出采空区的治理原则,根据采空区的不同种类提出不同的治理方法,在此基础上,结合具体采空区,提出采空区处理与采矿一体化理论,得出采空区处理的流程,并针对平朔东露天煤矿的实际情况,提出露天煤矿过采空区的安全措施。采空区处理与采矿一体化的研究,不仅对平朔东露天煤矿采空区的处理具有重要现实意义,也对国内外相类似的矿山具有重要的借鉴意义。
[Abstract]:There are many small coal mines within the mining boundary of Pingshuodong opencast coal mine. As a result of these small coal mines' long-term disorderly mining, no filling mining, mining rich and poor and so on, there are now a large number of underground mined-out areas in the boundary of Pingshuo East Open-pit Coal Mine. However, most of these goaf have no location, size and other specific data, which brings great hidden trouble to the safe and efficient production of opencast coal mine. In this paper, the goaf of Pingshuodong opencast coal mine is taken as the research object, the exploration of goaf, the calculation of the safety thickness of overlying strata in goaf, and the integration of goaf treatment and mining are studied. Firstly, this paper analyzes the working principle, advantages and disadvantages and applicable scope of the common methods of goaf detection. Combined with the actual situation of Pingshuo East opencast Coal Mine, the technology of goaf detection in Pingshuo East Open-pit Mine is obtained. By analyzing the relevant data, the paper sorts out the calculation parameters needed to calculate the safety thickness of overburden strata in goaf, and on this basis, through a variety of different theoretical methods and numerical simulation methods, The reasonable value of the safety thickness of overlying strata in goaf is obtained by comprehensive analysis. Finally, by analyzing the unique characteristics of goaf in the mining realm of open pit coal mine and combining the actual production of open pit coal mine, the paper obtains the principle of the treatment of goaf, and puts forward different treatment methods according to the different kinds of goaf, and on this basis, Combined with the specific goaf, this paper puts forward the theory of the integration of goaf treatment and mining, and obtains the process of goaf treatment, and puts forward the safety measures for overgoaf in Pingshuo East opencast coal mine according to the actual situation of Pingshuodong opencast coal mine. The research on the integration of goaf treatment and mining is not only of practical significance to the treatment of goaf in Pingshuo East opencast Coal Mine, but also of great significance for reference to similar mines at home and abroad.
