| 摘 要： | 研究了河南省南召县田家庄饰面用花岗岩矿的矿床地质特征及开采技术条件，分析了矿区地层、构造、岩浆岩、覆盖层及风化层地质特征，研究了矿体特征、矿石质量及其特征、断裂及节理和裂隙分布发育特征、矿石类型和品级、矿体围岩及夹石、矿床成因及找矿标志等矿床地质特征。通过水文地质、工程地质、环境地质调查工作，基本查明了矿区的水文地质、工程地质和环境地质条件，区内岩石类型简单，矿体及围岩主要为黑云母二长花岗岩，岩体呈块状结构，地质构造简单，不会形成岩体滑动，矿体与围岩工程地质条件稳定，不易发生矿山工程地质问题，工程地质条件为第二类简单型。矿石和废石不易分解出有害组分，但在矿山开采时会对原有地形地貌造成破坏，存在一定的不良地质灾害隐患。矿区地表附近无污染源，无放射性异常，环境地质条件中等。研究可作为矿山建设的依据。

| Abstract: | This paper studied the ore deposit geological characteristics and mining technical conditions of the Tianjiazhuang facing granite mine in Nanzhao County，Henan Province.The geological characteristics of the strata,structures,magmatic rocks,overburden and weathered layer in the mining area were analyzed,and the geological characteristics of the deposit,such as the characteristics of the ore body,the quality and characteristics of the ore,the distribution and development characteristics of faults,joints and fissures,the type and grade of the ore,the surrounding rocks and inclusions of the ore body,the genesis of the deposit and the prospecting signs,were studied.Through the investigation of hydrogeology，engineering geology and environmental geology，the hydrogeology，engineering geology and environmental geological conditions of the mining area were basically identified.The rock types in the area were simple，and the ore body and surrounding rocks were mainly black Mica monzonitic granite，the rock mass was massive，the geological structure was simple，the rock mass would not slide，the engineering geological conditions of the ore body and the surrounding rock were stable，and the engineering geological problems of the mine were not easy to occur，and the engineering geological conditions were the second type of simple type.Ore and waste rock were not easy to decompose into harmful components，but they would cause damage to the original topography and landforms during mining，and there were certain hidden dangers of adverse geological hazards.There was no pollution source near the surface of the mining area，no radioactive abnormality，and moderate environmental geological conditions.Research could be used as a basis for mine construction. |
