云南郝家河铜矿床是楚雄盆地砂岩型矿床的典型代表。在矿区大比例尺构造地质填图的基础上，运用矿田地质力学的理论和方法，筛选典型断裂，进行断裂面力学性质的鉴定，划分构造期次，厘定构造体系，并对区内不同期次、不同方向断裂的地质特征及其与成矿的关系进行了详细的阐述。认为自燕山期以来该区经历了 NE -SW 向→近 EW 向→NW -SE 向→近 SN 向4期构造主压应力的转换。燕山晚期 NW 向构造对早期成矿物质活化、迁移、重分配，造成铜的初始富集具有控制作用；燕山晚期-喜山早期近 SN 向断裂构造促使成矿物质富集，矿体形态多表现为层状、似层状；喜山早期 NE 向断裂构造促使含矿热液从地层中萃取大量含矿物质并发生再富集，形成富厚矿体；喜山中晚期近EW 向断裂构造主要对已形成的矿体造成破坏。

Haojiahe copper deposit is a typical representative of sandstone deposits in Chuxiong Basin,Yun-nan.On the basis of large scale tectonic geological mapping,this article uses the theory and method of ore fields of geomechanics to select the typical fractures to identify the mechanical properties of fracture surface,divides the construction period of time and set the tectonic systems,and also makes a detailed description on the rela-tionship between the geological characteristics of the faulted geology and the ore-forming in different period time and from different direction.Since Yanshanian,this area has experienced the transition from NE -SW trending→near EW trending→NW -SE trending→near S -N trending to the main constructional compressive stress.In late Yanshanian,NW trending structure has control function on the inchoate metallogenic material activation, migration and reconfiguration and enrichment of copper;between late Yanshanian and early Himalayan,near S-N trending structure prompted into enrichment of metallogenic material.The morphology of ore body emerged to be lamellar and stratoid;in the early Himalayan,NE trending structure promoted the ore fluid to extract a great number of mineral substance then enriched them again and formed rich ore body;in the middle-late Hima-layan,near EW trending structure caused damage to the ore body.
