【摘要】：隨著全球礦業(yè)熱潮逐漸褪去,國內(nèi)礦業(yè)形勢進(jìn)入新常態(tài),礦產(chǎn)資源需求增長放緩,產(chǎn)能嚴(yán)重過剩,礦產(chǎn)品價(jià)格一路下跌。在這種嚴(yán)峻的市場環(huán)境下,降低開采成本、安全高效開采成為礦山企業(yè)競爭和發(fā)展的必然選擇。隸屬于西北有色地質(zhì)勘查局的二里河鉛鋅礦,其Ⅱ1號(hào)礦體隨著鞍部深部開采,爆力運(yùn)搬采礦工藝遇到了一些技術(shù)難題,直接影響著礦山的生產(chǎn)效率和經(jīng)濟(jì)效益。本文在實(shí)際調(diào)查研究的基礎(chǔ)上,深入分析了二里河鉛鋅礦Ⅱ1號(hào)鞍部礦體開采時(shí)存在的問題,對(duì)爆破運(yùn)搬采礦工藝進(jìn)行了優(yōu)化研究,首先,介紹了爆力運(yùn)搬采礦方法在二里河鉛鋅礦實(shí)際應(yīng)用中存在的問題—爆破效果差及運(yùn)搬效率低下,針對(duì)這些問題,闡述了爆力運(yùn)搬采礦工藝優(yōu)化的研究原理及方法;其次,根據(jù)二里河鉛鋅礦鞍部礦體回采的實(shí)際情況,設(shè)計(jì)和訓(xùn)練適用于本礦山爆破參數(shù)優(yōu)選的網(wǎng)絡(luò)模型,并通過Matlab工具箱對(duì)訓(xùn)練好的BP神經(jīng)網(wǎng)絡(luò)進(jìn)行仿真,分析預(yù)測結(jié)果,從而優(yōu)選出最佳的爆破參數(shù);再次,根據(jù)鞍部礦體開采技術(shù)條件及采礦工藝,建立爆力運(yùn)搬礦石運(yùn)動(dòng)軌跡模型,并運(yùn)用Rocfall軟件對(duì)礦石運(yùn)搬過程進(jìn)行數(shù)值模擬,為類似開采條件的礦山計(jì)算爆力運(yùn)搬距離提供了一種新思路;最后,設(shè)計(jì)兩平行試驗(yàn)采場,應(yīng)用改進(jìn)前后的采礦工藝進(jìn)行回采。經(jīng)技術(shù)經(jīng)濟(jì)評(píng)價(jià),與原采礦工藝相比較,炸藥消耗降低7.5%,應(yīng)用效果良好。改進(jìn)后的爆力運(yùn)搬采礦工藝,不僅能夠有效地解決采場爆破及運(yùn)搬問題,從而保證工人作業(yè)安全,提高礦山經(jīng)濟(jì)效益,同時(shí)也為采用爆力運(yùn)搬工藝的類似礦山設(shè)計(jì)和生產(chǎn)管理提供了理論依據(jù),研究成果對(duì)于完善爆力運(yùn)搬采礦工藝具有指導(dǎo)意義。
[Abstract]:As the global mining boom fades, domestic mining has entered a new normal, demand for mineral resources has slowed, overcapacity has been severe, and mineral prices have fallen. In this severe market environment, reducing the mining cost and mining safely and efficiently becomes the inevitable choice for the competition and development of mining enterprises. The No. 1 orebody of Erlihe Lead-Zinc Mine, which belongs to the Northwest Non-ferrous Geological Exploration Bureau, has encountered some technical problems with the deep mining in Anbei, which directly affects the production efficiency and economic benefit of the mine. On the basis of actual investigation and research, this paper deeply analyzes the problems existing in the mining of No.1 Anchorage orebody of Erlihe Lead-Zinc Mine, and studies the optimization of blasting moving and lifting mining technology. This paper introduces the problems existing in the practical application of blasting force transport and lifting mining method in Erlihe lead and zinc mine. The blasting effect is poor and the moving and lifting efficiency is low. In view of these problems, the research principle and method of blasting force transport and lifting mining process optimization are expounded. According to the actual mining situation of the Anshan orebody in Erlihe lead-zinc mine, a network model suitable for the optimum selection of blasting parameters in this mine is designed and trained. The trained BP neural network is simulated by Matlab toolbox, and the prediction results are analyzed. Then the best blasting parameters are selected. Thirdly, according to the mining technical conditions and mining technology of Anbu orebody, the moving track model of blasting force is established, and the numerical simulation of ore transport and lifting process is carried out by using Rocfall software. This paper provides a new idea for calculating the distance of blasting force transport in mines with similar mining conditions. Finally, two parallel test stope are designed, and the improved mining technology is used for mining. Through technical and economic evaluation, compared with the original mining technology, the explosive consumption is reduced by 7.5%, and the application effect is good. The improved blasting force moving mining technology can not only effectively solve the problems of stope blasting and moving, but also guarantee the work safety of workers and increase the economic benefit of mines. At the same time, it also provides a theoretical basis for the design and production management of similar mines using blasting force transport and lifting technology, and the research results are of guiding significance for the improvement of blasting force transport and lifting mining technology.
