倾斜多变难采矿体的盘区机械化高效采矿技术

Application of panel mining technique in inclined ore bodies of severe-variation

尹格庄金矿床的赋存特点为储量大、埋藏深、品位低、形态多变 ,只有实行低成本、规模化开采 ,才能保持较好的经营效益。文中介绍了盘区机械化高效采矿法 ,通过采用全套无轨采矿设备联合作业、用光面崩矿技术和多种手段联合维护采场顶板、用水准测量和声发射定位系统动态跟踪监测顶板安全 ,实现了倾斜多变难采矿体的安全、高效、低成本开采。

Yingezhuang gold deposit has characteristics of large reserve quantity with low gold grade,ore bodies deeply positioned with severe variation of configuration.Thus,the strategy of low operation cost and large scale of mining should only be considered to ensure economic benefit from the operation.This paper explains the panel mechanized mining method of high efficiency.By use of complete set of trackless mining equipment with combined techniques of smooth blast with various maintaining measures to protect stope roof,level theodolite and acoustic emission-positioning system to dynamically monitor the roof,the operation of safety,high efficiency and low cost have been achieved for the ore bodies of severe variation of configuration in the mine.
