【摘要】：摘要：礦產(chǎn)資源屬于有限的、不可再生的極度寶貴資源,如何合理高效利用是擺在每一個(gè)礦業(yè)工作者面前的重要使命。邊界品位的確定就是礦產(chǎn)開(kāi)發(fā)中一個(gè)尤為關(guān)鍵的決策問(wèn)題,它的選擇直接影響到礦石儲(chǔ)量,進(jìn)而影響礦山的生產(chǎn)規(guī)模,最終開(kāi)采境界,設(shè)備選型和礦山生產(chǎn)壽命等。合理優(yōu)化邊界品位指標(biāo),對(duì)充分利用礦產(chǎn)資源,保障礦企利潤(rùn),增加資源儲(chǔ)量、延長(zhǎng)礦山的服務(wù)年限等有著重要的經(jīng)濟(jì)和社會(huì)意義。 本文運(yùn)用數(shù)學(xué)方法結(jié)合計(jì)算機(jī)技術(shù)對(duì)影響礦山邊界品位確定的各種因素進(jìn)行了具體分析研究,提出了利用蒙特卡洛模擬進(jìn)行多金屬生產(chǎn)礦山邊界品位優(yōu)化的新方法,建立了邊界品位優(yōu)化相關(guān)的數(shù)學(xué)模型,創(chuàng)建了礦山技術(shù)經(jīng)濟(jì)指標(biāo)與成本數(shù)據(jù)庫(kù),開(kāi)發(fā)了一套多金屬共伴生銅礦邊界品位動(dòng)態(tài)優(yōu)化管理軟件,從而為多金屬生產(chǎn)礦山的管理和邊界品位的優(yōu)化提供有力幫助。 通過(guò)研究,項(xiàng)目取得了一定的理論和實(shí)際成果： (1)分新建礦山、在產(chǎn)礦山和局部礦體三種情況建立了實(shí)現(xiàn)邊界品位方案優(yōu)化的地質(zhì)儲(chǔ)量模型、生產(chǎn)能力模型、投資模型、成本模型、收益模型、稅收與折舊模型、經(jīng)濟(jì)目標(biāo)模型和礦產(chǎn)品價(jià)格預(yù)測(cè)模型8個(gè)計(jì)算模型；給出了局部低品位礦石回收與否的具體決策方案。 (2)針對(duì)目前僅從單個(gè)因素或少數(shù)幾個(gè)因素來(lái)優(yōu)化礦山指標(biāo),未考慮多決策變量的整體優(yōu)化的現(xiàn)狀,詳細(xì)分析了影響礦山邊界品位確定的各種因素和生產(chǎn)投入變量,提出了利用蒙特卡洛模擬進(jìn)行邊界品位優(yōu)化的方法,并闡述了具體實(shí)現(xiàn)過(guò)程。 (3)對(duì)于多金屬共伴生礦床而言,如果單純的以某一元素作為評(píng)價(jià)對(duì)象來(lái)圈定礦體的話,勢(shì)必會(huì)產(chǎn)生巨大的資源浪費(fèi),故提出了運(yùn)用當(dāng)量品位概念進(jìn)行礦石邊界品位確定的方法,并具體研究了折算當(dāng)量品位的方法和公式。 (4)通過(guò)研究城門山銅礦技術(shù)經(jīng)濟(jì)指標(biāo)和開(kāi)采成本情況,利用SQL Server2008數(shù)據(jù)庫(kù)軟件和.NET4.0編程軟件,創(chuàng)建了城門山銅礦技術(shù)經(jīng)濟(jì)指標(biāo)與成本數(shù)據(jù)庫(kù)。利用數(shù)據(jù)庫(kù)可以輕松實(shí)現(xiàn)礦山技術(shù)經(jīng)濟(jì)指標(biāo)與成本信息的存儲(chǔ)、查詢、利用和整合,大大方便礦山的管理工作并且為礦床邊界品位動(dòng)態(tài)優(yōu)化提供了平臺(tái)及基礎(chǔ)數(shù)據(jù)。 (5)利用.NET4.0編程軟件,開(kāi)發(fā)了功能強(qiáng)大的邊界品位動(dòng)態(tài)優(yōu)化程序,該程序包含了影響邊界品位確定的各種計(jì)算模型,數(shù)據(jù)全面,測(cè)算過(guò)程邏輯清楚,操作簡(jiǎn)單,利用該程序測(cè)算出的邊界品位具有非常高的實(shí)用價(jià)值,能夠節(jié)約大量的成本和人力資源。 (6)結(jié)合技術(shù)經(jīng)濟(jì)指標(biāo)與成本數(shù)據(jù)管理和邊界品位測(cè)算兩個(gè)功能而創(chuàng)建的網(wǎng)絡(luò)版“多金屬銅礦邊界品位動(dòng)態(tài)優(yōu)化管理系統(tǒng)”軟件,只需建立一個(gè)服務(wù)器即可在網(wǎng)上進(jìn)行操作,為用戶單位和集團(tuán)公司搭建了一個(gè)可靠的資源共享管理平臺(tái),用戶能夠更加簡(jiǎn)單、快速、高效的使用系統(tǒng)來(lái)進(jìn)行技術(shù)經(jīng)濟(jì)指標(biāo)和成本的管理以及邊界品位優(yōu)化測(cè)算。
[Abstract]:Abstract: mineral resources are limited, non-renewable and extremely valuable resources. How to make rational and efficient use of mineral resources is an important task for every mining worker. The determination of boundary grade is a particularly critical decision problem in mineral exploitation, and its choice directly affects ore reserves. Thus affecting the production scale, the final mining boundary, the equipment selection and the mine production life of the mine, the reasonable optimization of the boundary grade index can make full use of the mineral resources, guarantee the profits of the mining enterprises, and increase the reserves of the resources. It is of great economic and social significance to extend the service life of mines. In this paper, the mathematical method combined with computer technology is used to analyze and study the factors affecting the determination of mine boundary grade, and a new method for optimizing the boundary grade of multi-metal production mines by Monte Carlo simulation is put forward. A mathematical model related to boundary grade optimization is established, a database of mine technical and economic indexes and cost is established, and a set of dynamic optimization management software for boundary grade of multi-metal associated copper mines is developed. Therefore, it is helpful for the management of polymetallic production mine and the optimization of boundary grade. Through the research, the project has achieved some theoretical and practical results:. The geological reserve model, production capacity model, investment model, cost model, income model, tax revenue model and depreciation model of boundary grade scheme are established in the three conditions of producing mine and local ore body. The economic target model and mineral product price prediction model are used to calculate 8 models, and the specific decision scheme of local low grade ore recovery or not is given. In view of the present situation that only single factor or a few factors are used to optimize the mine index and the multi-decision variables are not considered, the factors affecting the determination of mine boundary grade and the production input variable are analyzed in detail. A method of boundary grade optimization by Monte Carlo simulation is proposed, and the realization process is described. 3) for the polymetallic co-associated ore deposit, if a single element is used as the evaluation object to delineate the orebody, it will inevitably lead to a huge waste of resources. Therefore, a method of determining the ore boundary grade by using the concept of equivalent grade is put forward. The method and formula of converting equivalent grade are studied in detail. By studying the technical and economic indexes and mining cost of Chengmenshan Copper Mine, the author makes use of SQL Server2008 database software and .NET4.0 programming software. The database of technical and economic index and cost of Chengmenshan Copper Mine is established. The database can easily realize the storage, query, utilization and integration of mine technical and economic index and cost information. It greatly facilitates mine management and provides platform and basic data for dynamic optimization of ore deposit boundary grade. In this paper, a powerful dynamic optimization program for boundary grade is developed by using the program software .NET4.0. The program contains various calculation models that affect the determination of boundary grade. The program has the advantages of comprehensive data, clear calculation logic and simple operation. The boundary grade calculated by this program is of high practical value and can save a lot of cost and human resources. Based on the two functions of techno-economic index, cost data management and boundary grade calculation, the network version of "dynamic optimization management system for boundary grade of polymetallic copper mine" is developed. Only one server is needed to operate on the network. A reliable resource sharing management platform is built for user units and group companies. Users can use the system more easily, quickly and efficiently to manage the technical and economic indicators and cost and optimize the boundary grade.
