【摘要】：钢铁产业是一个国家的工业命脉，而炼铁需要石灰石为溶剂，除了脉石。炼制钢材一般利用生石灰当做造渣原料，去除硫及磷有毒物质。所以石灰石在我国的工业生产中起到十分巨大的作用。随着产业向前进步，，在运输铁矿石的成本上也随之增高。随着市场对矿石需求量的不断增大，矿山的推进速度也随之加快。矿山上任何一种单一工艺都不可能完全适用于矿山的整个寿命。卡布其山坡露天矿所用的溜井随着社会对矿石需求量的增大，采掘速度的加快，降段也越来越频繁，使得溜井上端到主平硐水平的垂直距离也越来越短。随着溜井上端至主平硐水平的垂直距离变小，平硐溜井开拓运输方案的优势将慢慢失去。当到达某一水平时，利用平硐溜井开拓运输系统在运输成本方面将不优于其他运输系统。根据矿山利益的最大化，随之而来的就是用其它开拓运输方案代替平硐溜井联合运输方案。本文以乌海市卡布其山坡露天石灰石矿地质资料为工程背景、以6号溜井井口1395米水平为起始点并以每降段12米为一个区间单位，通过理论分析计算出平硐溜井方案和全汽车运输方案的运输成本随开采水平的变化，会有一定的变化规律。通过变化规律来研究推断出平硐溜井开拓运输方案与全汽车开拓运输方案的衔接水平。主要工作如下： (1)根据卡布其矿地质和矿床条件，综合分析衔接开拓运输系统为全汽车运输。 (2)通过实地考察，找出两方案比较段的影响因素；去卡布其石灰石矿实测并向相关技术人员收集两方案影响因素的相关数据。 (3)根据实测数据分析计算得出：溜井上端1395米处与主平硐水平的高差为85米，主平硐口至破碎站的距离为1.2km；1395米水平采场至破碎站的汽车运输距离为1.3km。并且在出入口水平1341米以上，溜井每降段12米，汽车运距缩短0.15km。（4）通过实测数据与理论分析计算得出两种方案的运输成本随标高变化的规律，再构造出相应的函数并用word绘制出相对应的函数图像。（5）通过函数的计算和函数图像比较，得出平硐溜井开拓运输系统方案转全汽车运输开拓运输方案的衔接水平。
[Abstract]:The iron and steel industry is the lifeblood of a nation's industry, and ironmaking requires limestone as a solvent, except gangue.Smelting steel generally uses quicklime as slagging material to remove sulfur and phosphorus toxic substances.So limestone plays a very important role in China's industrial production.As the industry advances, so does the cost of transporting iron ore.With the increasing demand for ore in the market, the speed of mining is accelerating.No single process in a mine can be fully applicable to the whole life of a mine.With the increasing demand for ore, the speed of mining and the falling section are more and more frequent, which makes the vertical distance from the upper end of the pass shaft to the main adit become shorter and shorter.As the vertical distance from the upper end of the pass well to the horizontal level of the main adit becomes smaller, the advantage of the development and transportation scheme will be gradually lost.When a certain level is reached, the transportation system developed by Adit pass will not be superior to other transportation systems in terms of transportation cost.According to the maximization of mine benefits, other development and transportation schemes are followed.Based on the geological data of open-pit limestone mine on Kapuchi hillside in Wuhai City, this paper takes 1395 m level of No. 6 pass well head as the starting point and takes 12 meters of each descending section as an interval unit.Through theoretical analysis, it is found that the transportation cost of the adit pass plan and the whole vehicle transportation plan varies with the mining level, and there will be certain changes in the law.By studying the changing law, we infer the connection level between the development and transportation scheme of adit pass well and the whole automobile development and transportation scheme.The main tasks are as follows:1) according to the geology and deposit conditions of Kapuchi ore deposit, it is analyzed that the transportation system is the whole automobile transportation system.(2) through the field investigation, the influence factors of the two schemes are found out, and the data of the influencing factors of the two schemes are collected from the technicians concerned.In addition, at the entrance level of 1341 meters or more, the vehicle distance is shortened by 0.15 km per 12 meters in the slide well.4) based on the measured data and theoretical analysis, the law of transportation cost varying with elevation is obtained, and the corresponding functions are constructed and the corresponding function images are plotted by word.5) through the calculation of function and the comparison of function image, the connection level of the scheme of open up transportation system of adit and pass well to the whole automobile transportation development transportation scheme is obtained.
