摘　　要：为满足河北省当地建材市场需求,提交一处可供开发利用的饰面石材矿产地,在河北省青龙县肖营子勘查区开展饰面用花岗岩矿勘探工作。在详细查明矿区地质特征基础上,对矿区地层、构造及矿体特征进行了分析研究,发现肖营子矿区二长花岗岩适合作为饰面石材开发利用。在矿区内选取10处采样点测定矿体图解荒料率,并通过校正,得出矿体理论荒料率,估算荒料资源量。同时综合分析矿石加工技术性能与综合利用问题,为矿区资源开发利用提供一定的科学依据。In order to meet the demand of local building materials market inHebei Province,one new mining area for decorative stone is proposed for the development and utilization,and the prospecting work for decorative surface granite deposit is carried out at Xiaoyingzi exploration area in Qinglong County.On the basis of identifying the geological characteristics of the mining area in detail,the strata,structure and orebody characteristics are studied in the mining area.It is found that the monzonite granite in Xiaoyingzi mining area of Qinglong County is suitable for development and utilization as the decorative stone.In the mining area,10 survey points are selected to test the pictorial block rate,and through correction,the theoretical block rate of orebody is obtained.The block resources reserve is estimated,and the ore processing technical performance and comprehensive utilization are studied.It is provided the scientific basis for the development and utilization of mineral resources in the mining area.
