我矿属前震旦纪沉积变质矿床。现分别由东山、西山两个采矿场开采。东山矿体厚度变化系数为44.25～66.48％,品位变化系数为50.72～55.08％,构造较复杂,属磷矿第四勘探类型。西山矿体厚度变化系数为13.04～26.97％,品位变化系数为57.72～62.41％,属第三～四勘探类型。鉴于矿体变化较大,加之深部多为C_1级储量,因此,开展生产勘探,提高勘探程 Mine is a former Sinian sedimentary metamorphic deposit. Now by Dongshan, Xishan mining two mining. Dongshan ore thickness coefficient of 44.25 ~ 66.48%, grade change coefficient of 50.72 ~ 55.08%, the structure is more complex, is the fourth exploration type of phosphate rock. The thickness variation coefficient of Xishan ore body is 13.04 ~ 26.97% and the variation coefficient of grade is 57.72 ~ 62.41%, belonging to the third to the fourth exploration types. In view of the great changes in the ore body, combined with the deep mostly C_1-level reserves, therefore, to carry out production exploration and improve prospecting process
