安庆铜矿Ⅰ号矿体生产勘探网度研究

STUDY ON THE PROSPECTING NETWORK OF No. 1 OREBODY IN THE ANQING COPPER DEPOSIT, ANHUI

安庆铜矿Ⅰ号矿体是一隐伏矿体,目前采用VCR法进行采矿作业。根据目前VCR法尚无明确的网度规定和实际经验借鉴的实际情况,通过数学模型的建立,以及对影响勘探网度因素,包括厚度变化因素、矿化变化因素、边界变化因素、矿体内外接触带变化因素、矿石品位及内部结构变化因素和构造因素等六个方面的分析,结合实际生产探矿情况,认为目前矿山生产探矿采用网度20m×(15～20)m是基本合理的,并提出了改进意见。

The No. 1 oredody of the Anqing Cu deposit, that is a concealid orebody, is mined by the VCR method. The VCR method is a new method, which lacks strict prospecting network rule and practical experienceto be used for reference. In this paper rationalityon the prospecting network of the No. 1 orebody is analyzed by the established mathematical modeland influence factors including thickness, mineralization, ore border, inside and outside contact zones, ore grade and interior structure. Combined with the fact of prospecting, it is indicated that the present network [20 m×(15-20) m] is basically reasonable.
