The article discusses the principle and method that establish coal bed geological model and construct geological information database by computer in details , and analyzes the character of every traditional estimate - value methods and the basic principle thdt is chosen in the process of estimate - value . with curved surface spline function and neural network , the basic principle of estimating value was submitted . according to the condition of majata pit coal mine , 1 establish the two dimension web geological information database that includes the picture function and establish the geological information management system that can real - time update , extract information and easy to operate 本文詳細論述了利用計算機建立礦床地質模型,構造地質信息庫的基本原理和方法,剖析了各種傳統估值方法的特點及其在估值過程中選用的基本原則,在此基礎上提出了采用曲面樣條函數和人工神經網絡方法進行估值計算的基本原理。并針對馬家塔露天礦的具體礦床地質條件,建立了含圖形功能的二維網狀地質信息庫,開發了具有動態更新、提取各種地質信息的功能模塊,形成了一套功能齊全、實用可靠、操作使用方便的地質信息管理系統。

By using subarea - subsection mining method , multi - channel layout program , heidaigou open - pit coal mine has overcomed the technological continuity problems appearing in bench combination and has fully improved the capacity of existing equipments , so that the transportation distance has been reduced and enormous economic benefits have been gained 在此過程中,黑岱溝露天煤礦通過分區分段開采、多通道布置等方案,克服了并段臺階工藝接續過程中出現的問題,最大限度的增加現有設備生產能力,減少運距,創造了巨大的經濟效益。

In view of mining technology modification from shovel - truck to dragline , heidaigou open pit coal mine uses shovels and trucks for combining the original benches with the new bench which meets the requirement of dragline operation 摘要針對黑岱溝露天煤礦的特點、現有開采工藝等,具體研究該礦在擴大生產能力方案實施過程中由單斗鏟汽車工藝向吊斗鏟倒堆工藝過渡中所存在的問題以及合理的礦山工程銜接方案,以達到吊斗鏟開采工藝設計臺階要求。

Based on creep test of soft sheaf , according to time effect of long term strength , fuxin haizhou open - pit coal mine slope is exemplified to study dynamic stability of side slope , and method for predicting the instability of this slope is discussed 摘要以阜新海州露天礦邊坡為例,在弱層流變試驗的基礎上,依據其長期強度的時間效應,對該處邊坡進行了穩定性動態評價,探討了該類型邊坡失穩預測的方法。

In 1982 , his company signed an agreement to create a huge open - pit coal mine in shanxi province , which had just been designated as the nation ' s new energy base 1982年,哈默的公司簽署了協議創建中國最大的露天煤礦,隨后這里便變成了中國的新能源基地。
