Abstract
The main content of the design is the underground mining design for the Hu Jiali Mine of Huangjingdong area in Hunan Province,and designed annual production capacity of 10 million tons.
The design of the main tasks is to mine geological,hydrological data and prospecting line profile based on the geological condition of the ore body to understand. According to the mine geological data design development system,should make the mining development system has the advantages of simple structure,make the capital construction engineering quantity reduction,and can achieve the production capacity,the technical and economic analysis of development,to achieve the optimal system scheme and selection of mining methods.
Throughthe technical and economic analysis and comparison,this design opened up by inclined shafts,and the mining method used toupward horizontal slice filling method. This design has been designed for underground transportation and inclined shaft hoisting. This design introduces a pioneering method,mining method and the method of ventilation used in the deposit,and there has a comprehensive description about that. At the same time,it also determined the development and mining of the section size of the tunnel,mine block size,and calculate the amount of development and mining projects,etc.
The design used in the some parameters used is similar to mine data,and to "Modern Mining Handbook",and cooperate with other reference way design. The whole design in accordance with the design standards,and adopt AutoCAD computer graphics,to meet the design requirements.
Key words: Lead and Zinc Mining; Mine Development System;Inclined Shaft Hoisting; Upward Horizontal Slice Filling Method; Mine Ventilation
