| 摘 要： | 针对鸡冠嘴金矿二期采区矿体(群)延深较大、走向较短、在垂向上中部较厚、品位较高呈“菱形”变化的特点，通过技术经济比较和岩石力学研究论证，并结合国内、外类似矿山的生产实践，提出并采用了不同于常规的首先开采矿体(群)中部的开采方法，从而为提高矿山生产初期的经济效益，尽早偿还基建贷款提供了一条新的成功经验。

| Abstract: | According to the features of orebody such as greater deepening,shorter strike line,thick middle part,higher grade and diamond like variation of grade,again,through the comparisons of technical economy and lithomechanic proof besides using the experience of similar mines home and abroad for reference,this paper proposes and adopts an unconventional mining method,that is to say,the mining operation firstly begin at the middle part of the orebody which result in the improvement of economic benefit in initial stage and paying back the loan for capital construction as early as possible. |

| Keywords: | to mine the middle part of the orebody first unconventional mining sequence economic benefit in initial stage |
