摘　　要：矿区属片麻岩、片岩混合岩化型（碎云母）矿,矿床勘探类型为Ⅱ类。在矿区内发现厚大矿体一个,呈似层状,矿体分布标高为150-252m,埋深0-5m。矿体倾向20°-40°,倾角20°-30°,矿体长770m,厚度11.34-187.38m,片麻岩（碎云母）矿平均碎云母含矿率67.13%。估算片麻岩（碎云母）风化壳型矿（122b）＋（333）资源量矿石量398.37万吨,碎云母矿物量270.16万吨。估算采矿证标高范围内风化壳型和原生型矿（122b）＋（333）资源量矿石量1410.33万吨,碎云母矿物量946.71万吨。矿区水文地质条件及工程地质条件简单,环境地质条件中等,矿石易采易选,加工性能良好。The mining area is the gneiss, schist migmatization type（broken mica）,ore deposit types and prospecting for class Ⅱ. It was found a large and thick ore body in the mining area, the stratoid, orebody distribution elevation is 150-252m, depth of 0-5m. The orebody dip of 20 degrees to 40 degrees, 20 degrees to 30 degrees angle, ore body length of 770 m and a thickness of 11.34-187.38 m, gneiss（broken mica） average crushing mica mine ore rate 67.13%. Estimation of gneiss（broken mica） weathering crust type ore（122b） ＋（333） the amount of resources and ore quantity3983700 tons, broken mica mineral volume of 2701600 tons. Estimation of mining permits elevation range of weathering crust type and original type ore（122b）＋（333） the amount of resources and ore quantity 14103300 tons, broken mica mineral volume of 9467100 tons. The geological conditions of hydrogeology and engineering geological conditions of mining area environment is simple, easy to pick and choose the medium of ore, good processing performance
