固阳县宝丰金矿Ⅲ号矿体开采方案设计 关键词:下盘竖井开拓;浅孔留矿法;中央对角式通风; Abstract The design is Baofeng Guyang mining gold ore body No. Ⅲ program design. The output of designed is annual 100,000 tons,and its life is service for 27 years. The design include some contents as follow:Comparing the choice to the program of development,designing the methods of extraction,designing ventilation systems and designing the hoisting and the transportion system and so on .In this mine,the development is the under footwall of the vertical shafts, and design the mine between the exploration line of 47 ~ 55. Mining method for the short-hole shrinkage method, the digging height is 50 meters, and in 5 phases layout the roadway .The ventilation system adopt the central-diagonal ventilation system, the main shaft use the single cage to hoist, and the two ventilation shafts layout in the two wings of the collapse area of the ore body as a safety exit. The drainage system adopt the integrated drainage. In addition, such the size of the shaft section, the size of the road section , the choose of the electric locomotive, the choose of the the mine car, the choose of the drawing equipment , the choose of the ventilation equipment, the choose of drain equipment are also related to the design Keywords: Under footwall of the vertical shafts development; Short-hole shrinkage method; Central-diagonal ventilation system; 目 录 摘 要I Abstract II 第一章 矿区概况及地质特征…………………………………………………- 5 - 1.1 矿区概述……………………………………………………………………- 5 - 1.2 矿区地质特征………………………………………………………………- 7 - 1.2.1 区域地质概况………………………………………………………- 7 - 1.2.2 矿区地质特征……………………………………………………- 11 - 1.2.3 矿床地质特征……………………………………………………- 16 - 1.2.4 矿床成因及找矿标志……………………………………………- 23 - 1.3 矿床开采技术条件…………………………………………………………- 24 - 1.3.1 水文地质…………………………………………………………- 25 - 1.3.2 工程地质…………………………………………………………- 30 - 1.3.3 环境地质…………………………………………………………- 32 - 第二章 矿区
