广东博罗石陂坑矿区夹石成因及综合利用分析

Analysis on Causes and Comprehensive Utilization of Horse-stone in Shipikeng Mining Area of Boluo County,Guangdong Province

广东省博罗县石陂坑矿区为一处中型的建筑用片麻岩矿山,矿体中发育有一层水饱和抗压强度偏低的夹石。从多方面对夹石的形成原因进行分析,认为夹石形成的原因与夹石的岩性、矿区构造、岩石片麻理构造以及岩石发育微细裂隙等相关。为了提高资源利用率,减少占用土地资源,对夹石的综合利用方向进行分析,认为夹石可用作砌石料原岩使用。

The Shipikeng mining area in Boluo County,Guangdong Province is a medium-sized gneiss mine for construction.There is a layer of horse-stone with low water saturation compressive strength in the ore body.The causes of the formation of the rock are analyzed from many aspects,and it is considered that the causes of the formation of the rock are related to the lithology of the rock,the structure of the mining area,the gneissic structure of the rock and the development of fine cracks in the rock.In order to improve the utilization rate of resources and reduce the occupation of land resources,the comprehensive utilization direction of stone is analyzed.According to the test results,it is considered that the horse-stone can be used as the raw rock of masonry.
