strip mining

Aiming at the coal under the building , rail and water , difficultly - mined coal and the side of strip mine , hardly mined , but it is utilization for the ucg study on field test of air coal gas , water coal gas , rich oxygen coal on the side of strip the side of strip mine mine of fu xin , using the ucg for the mineral well , getting the method for building stove of ucg , obtain different coal gas group and heat value for the different gasification craft high volatile , multiple thin coal seams on the side of strip mine are suitable to underground coal gasification to produce middle low heat value gas 摘要針對“三下”煤層,難采煤層,復雜煤層以及露天邊坡剩余的煤炭資源,并工開采不經濟或難以開采,可利用煤炭地下氣化將這些殘余資源得以回收利用,試驗利用礦井式煤炭地下氣化方式,對阜新礦露天邊坡進行了空氣煤氣、水煤氣、富氧煤氣的工業性試驗研究,通過煤炭地下氣化工業性試驗,得出在露天邊坡礦井式氣化建爐方式,不同氣化工藝的煤氣組分,熱值。

The thesis detailedly discusses a kind of optimize method on genetic algorithm , and points out the advantage obout utilizing genetic algorithm to solve large - scale non - linear system . through the study on large - scale strip mine truck real - time dispatch system , proposes the optimize model of strip mine truck real - time dispatch system , and utilizes the characteristic of genetic algorithm , provides a method of using genetic algorithm to solve the optimize model , designs the genetic operators at the same time . by the program language of matlab , develops strip mine truck real - time dispatch system . the system has the advantage of simpless and perfect function , proposes powerful sustain for strip mine ' s production and decision - making 本文詳細討論了遺傳算法這種優化方法,指出了遺傳算法在解決大型非線性系統優化問題時的優越性。通過對大型露天礦卡車調度系統的研究,建立了露天礦卡車實時調度系統的優化模型,并借助于遺傳算法自身的優點,給出了應用遺傳算法解算該優化模型的編碼方法,設置了相應的遺傳算子。并用matlab編程語言開發了露天礦卡車實時調度系統,該系統具有操作簡單和功能較完善等優點,為露天礦的生產決策提供了強大的支持。

Making use of the ood development twice to auto cad , this thesis draws up to the complete software package of management system of ore blending and realizes the management of the ore blending in the strip mine by the computer 本論文利用面向對象的編程設計方法對計算機輔助設計autocad軟件包為平臺進行了二次開發,編制完成了相應的配礦管理系統軟件,實現了計算機輔助露天礦配礦管理。

China ' s industrial growth depends on coal , which is plentiful but polluting , from strip mines like this one in shenmu , shaanxi province 中國的工業發展依賴煤礦,盡管煤礦資源豐富但是燃燒煤礦卻非常污染環境,就像山西省的沈木的這家裸礦。

China ' s industrial growth depends on coal , which is plentiful but polluting , from strip mines like this one in shenmu , shaanxi province 中國工業發展離不開煤炭資源,其儲量豐富但對環境污染嚴重,圖為山西深木縣煤礦。
