江西金山金矿田矿床工业指标的探讨

Discussion on Deposit Industrial Indices of Jiangxi Jinshan Gold Mine Field

金山金矿田金山、石坞、朱林西、雷高雾4个矿区(床)同产于一条含矿剪切带,主矿体为同一地质体,但各矿区(段)分别采用"1、3、5","1、2、4"指标圈矿,技术上不尽合理,且与当前黄金价格变化脱节。据近年黄金市场价格、矿山技术经济指标,采用"1、1.5、2.2"指标重新圈矿,矿体变得厚大,走向倾向连续性更为稳定,四个矿区可利用资源储量由原来70 183.54 kg增加到106 757.45 kg,矿块生产能力有所提高,矿区的服务年限有所延长。

Jinshan mine area （deposit）, Shiwu mine area （deposit）, Zhulinxi mine area （deposit） and Leigaowu mine area （deposit） in Jinshan gold mine field are occurred in an ore-bearing shear zone, main ore body is the same geological body, but each mine area （section） adopts＂ 1, 3, 5＂ and ＂1, 2, 4＂ indices for mine circle, it is not reasonable on technology and it is not consistent with current gold price change. According to recent gold marketing price and mine technical and economical indices, ＂1,1.5,2.2＂ index is adopted for mine circle again, ore body becomes thick and large, continuity of strike and trend is more stable, and the available resource reserve in four mine areas is increased from 70 183.54 kg to 106 757.45 kg, by which it can increase productive capacity of ore block and extend the service life of mine area.
