中文摘要：

矿石的形成条件与其物理力学参数存在诸多内在联系。根据现场勘察采集的数据资料阐述了我国南部磷矿石埋藏的地质条件,对湖北、贵州两个地区磷矿企业所属矿石的矿床岩石学特点,沉积型磷块岩赋存状态、磷块岩结构构造和磷灰石强度的相互关系进行对比研究。得知两地磷矿于同一地质时期形成,储量大、分布面积较广,但各自矿体的有害杂质含量、高品位富矿分布、矿石细观结构及力学性质存在明显差异。

英文摘要：

There are many inner link between the formation condition of the mineral and its physical and mechanics parameters.This paper expounds phosphate rock buried geological conditions in the south according to the data from the field.Many aspects of the phosphate rock regions in Guizhou and Hubei have been carried on the comparative study such as petrological characteristics of ore deposit,depositional phosphate rock occurrence state and the inter relations between phosphate rock structure and their strength.Know that both phosphate rock formed in the same geological period,large reserves,has a wide distribution area,but the harmful impurity content,high grade of the ore bodies distribution of rich ore,ore mesoscopic structure and mechanical properties exist obvious difference.
