【摘要】：论文从白音华三号露天煤矿开采现状及现有的设备条件出发,综合运用数学建模、技术经济学、露天采矿学原理和半连续工艺系统等相关理论,研究自移式破碎机半连续工艺在白音华三号露天煤矿中的应用。白音华三号露天煤矿采场处于转向阶段,首先研究了对白音华三号露天煤矿采场转向期间自移式破碎机半连续布置使用的可行性进行,通过计算分析得出露天煤矿采场转向期间,自移式破碎机半连续工艺系统的效率大大降低并且单位运营成本高,因此白音华三号露天煤矿转向期间不适宜布置和使用自移式破碎机半连续工艺系统。此外研究了白音华三号露天煤矿采场转向完成后自移式破碎机半连续工艺系统系统布置水平进行,通过岩石模型及剖面确定了自移式破碎机半连续工艺系统的布置水平为930水平并且后期不再跨台阶移设。随着采场的发展,后期露天矿西端帮发展到境界转折处,需要调整自移式破碎机半连续工艺系统,研究了露天矿境界转折时,自移式破碎机半连续工艺系统的过渡方案,通过经济比较确定了在境界转折时增加两条带式输送机的过渡方案。最后通过统计分析了其他相似露天矿的实际生产数据,确定了经济指标取值,进而得出了白音华三号露天煤矿布置自移式破碎机半连续工艺系统的经济效益。
[Abstract]:Based on the present situation of Baiyinhua No. 3 opencast coal mine and the existing equipment conditions, this paper synthetically applies the related theories, such as mathematical modeling, technical economics, opencast mining theory and semi-continuous process system, etc. The application of semi-continuous process of self-moving crusher in Baiyinhua No.3 opencast coal mine is studied. Baiyinhua No. 3 opencast coal mine stope is in the turning stage. Firstly, the feasibility of semi-continuous arrangement of self-moving crusher in Baiyinhua No. 3 opencast coal mine is studied. Through the calculation and analysis, it is concluded that the efficiency of the semi-continuous process system of the self-moving crusher is greatly reduced and the unit operating cost is high. Therefore, Baiyinhua No.3 opencast coal mine is not suitable for layout and use of semi-continuous process system of self-moving crusher during steering period. In addition, the layout level of semi-continuous process system of self-moving crusher after the completion of stoping turn in Baiyinhua No. 3 opencast coal mine is studied. According to the rock model and the section, the arrangement level of semi-continuous process system of self-moving crusher is 930 level and no step shift is achieved in the later stage. With the development of stope, in the late stage, the western end of open-pit mine develops to the turning point of boundary, so it is necessary to adjust the semi-continuous process system of self-moving crusher, and study the transition scheme of semi-continuous process system of self-moving crusher when the boundary of open-pit mine is turning. Through economic comparison, the transition scheme of adding two belt conveyors at the turning point of boundary is determined. Finally, through statistical analysis of the actual production data of other similar open pit mines, the value of economic indexes is determined, and the economic benefits of semi-continuous process system of self-moving crusher arrangement in Baiyinhua No. 3 opencast coal mine are obtained.
