摘要:
为掌握不同地域的磷块岩蕴藏地层的构造特点、高品位富矿分布、脉石结构以及力学性质之间的相互作用机理. 文章对我国中南湖北磷矿和西南贵州磷矿进行对比研究. 根据两矿区的地勘资料,同时结合电镜扫描、声波透射试验、破碎筛分等检测途径,从磷块岩的地层分布、构造类型、矿石结构、完整性及破碎后的颗粒级配等方面逐一分析,结果显示:首先西南片区磷块岩的震旦纪临海地理位置导致该区域矿体P2O5平均含量高,富矿储量大且共生矿物种类多,但岩体更为破碎. 其次宏观上岩体内部裂隙等弱面控制着磷块岩岩体的稳定性,而在细观层面,晶间结合力是矿石力学性质的控制因素.
Abstract:
To grasp the interaction mechanism of the structural characteristics of phosphorus block in differentregions, a comparative study on distribution of high - grade ore, gangue structure and mechanical properties fordifferent phosphate ores from Hubei and Guizhou was carried out. According to geological survey data of twomining areas, the stratigraphic distribution, tectonic type, ore structure, integrity and granular gradation ofphosphate rock were analyzed systematically by the electron microscopy, the acoustic transmission test and thecrushing screening. As the results shown, the sepecial coastal geography in Sinian Period results in thephosphate ore with a large reserves in the southwest area containing a high content of P 2 O 5 , although it containsmany kinds of paragenic ores so as to be easily broken. Furthermore, the stability of the rock is controlled by theinternal fissure at macro - level, but the inter crystal force is the controlling factor for the mineral mechanicalproperty at micro - level.
