摘　　要：狮子山矿区饰面用灰岩矿矿体走向、倾向延伸较稳定,厚度较大,具有较大的规模。为了解矿区饰面用灰岩矿的品质及特性,对饰面用灰岩矿的成矿地质特征及矿石质量进行了研究。根据矿石颜色特性等工艺性能将矿区饰面用灰岩分为“龙山云雾”和“龙山黑”2个品种。矿区内石材力学性能及放射性等各项指标均达到中—高密度的A类装饰板材要求,其花色品种优美,属高档饰面石材品种,可广泛用于建筑内外装饰。Limestone ore body for facing in Shizishan mining area is relatively stable in direction and tendency extension,with larger thickness and larger scale.In order to understand the quality and character⁃istics of the limestone ore for veneer in the mining area,the mineralization geological characteristics and ore quality of the veneer limestone ore are studied.According to the color characteristics of the ore and oth⁃er technological properties,the limestone used in the mining area is divided into two varieties:"Longshan Yunwu"and"Longshan Black".The mechanical properties and radioactivity of the stone in the mining area all meet the requirements of medium-high density Class A decorative panels.The variety of colors is beauti⁃ful,and it is a high-end decorative stone variety,which can be widely used for interior and exterior decora⁃tion of buildings.
