【摘要】：矿山运输系统是矿山露天生产的主要环节之一,其投资在整个矿山建设中占比较大,如决策失误,将造成重大损失。本文以玉龙石膏矿运输系统为研究对象,通过对国内外运输系统的现状及发展趋势、露天矿广泛应用的运输方式进行分析,结合玉龙石膏矿区建设条件,对比了单一公路运输、胶带运输和公路—破碎站—胶带联合运输三种运输方案,最终确定了矿山采用公路—破碎站—胶带联合运输方式。该运输系统具有如下特点：1、该运输方案,在前期投资和后期运行中,比单一公路运输具有很大的成本优势。2、相对于单一胶带运输,成本差别不大,但能更好适应矿区开采面的变化,缩短建设周期,克服地形多变,保证开采的连续性。3、从开采面至破碎站的公路运输部分,采用沿高程+1000米左右在青杠岗外围修建一条1.3km运矿路比直接从青杠岗开挖一条双壁沟修建一条0.8km运矿路,建设成本更低、更安全。4、该运输方式中的胶带运输部分借鉴了集团公司灰石矿山胶带运输机技术经验,利用重力势能发电,估计年发电量约300万度。5、该运输方式不仅能满足企业年产400万吨的运输需求,同时充分考虑了现代社会对企业环保、节能等的要求,体现了现代露天矿山运输系统高效、节能、低运费的发展方向。
[Abstract]:Mine transportation system is one of the main links of mine open-pit production, and its investment accounts for a relatively large proportion in the whole mine construction. If the decision-making is wrong, it will cause a great loss. This paper takes the transportation system of Yulong gypsum mine as the research object, through the analysis of the present situation and development trend of the transportation system at home and abroad, the widely used transportation mode of open-pit mine, combined with the construction conditions of the Yulong gypsum mine, compares the single road transportation, Tape transport and road-crushing station-belt combined transport are three kinds of transport schemes. Finally, the road-crushing station-belt combined transport mode is adopted in the mine. The transport system has the following characteristics: 1, the transport scheme, in the early investment and later operation, has a great cost advantage over the single road transport. 2, compared with the single belt transportation, the cost difference is not big. But it can better adapt to the change of mining surface, shorten the construction period, overcome the changeful terrain and ensure the continuity of mining. 3, the road transportation part from the mining surface to the broken station, The construction of a 1.3km transportation road on the periphery of Qingjianggang along an elevation of about 1000 meters is less expensive and safer than the construction of a double-walled ditch directly from Qinglever post to build a 0.8km transportation road. The belt transport part of this transportation mode draws on the technical experience of the belt conveyor in the limestone mine of the Group Company and uses the gravitational potential energy to generate electricity. It is estimated that the annual output is about 3 million degrees. The transportation mode can not only meet the transportation demand of 4 million tons per year, but also fully consider the requirements of modern society for environmental protection, energy saving and so on. It embodies the development direction of modern open-pit mine transportation system with high efficiency, energy saving and low freight.
