摘要

本文介绍了萨颜山东部Zun-Kholbinsky、Barun-Kholbinsky、Konevin-sky三个金矿床的初始应力研究的主要结果，研究范围为120 ~ 940 m。采用槽卸载法进行了现场测量，并在49种岩石压力情况下进行了主应力反算。确定了关键的地质力学因素，并估计了这些因素组合下的自然应力平均统计参数。

ESTIMATED ANALYSIS OF THE NATURAL STRESS FIELDS COMPLEXITY IN EASTERN SAYAN GOLD-ORE VEIN DEPOSITS

The article presents the main results of studies of initial stresses of three gold vein de-posits located in the Eastern Sayan Mountains: Zun-Kholbinsky, Barun-Kholbinsky, Konevin-sky, in the depth range of 120…940 m. Insitu measurements by the slot unloading method and reverse calculation of primary stresses on the basis of 49 rock pressure cases were made. Key geomechanical factors were determined, and average statistical parameters of natural stresses depending on the combination of these factors were estimated.
