画眉坳矿区已有近40年的开采历史,六十年代回采至六中段时,表现有明显的地压活动,特别是在F_1主干破碎带附近,愈向深部地压活动越来越显著和频繁。1979年我们对画眉坳主矿带的地压现象与地质构造进行了调查和研究,现分述如下:一、矿区开采及其地质概况画眉坳矿区位于兴国和宁都两县交界的山区,地形为北东高而西南低,海拔最低点为520米。矿区出露地层主要是震旦纪浅变质岩系,根据岩性鉴定,其地层自北而南,自上而下分为五层,主要为石英云母片岩、云母石英片岩及变质石英砂岩,含钨铍石英薄矿脉群则产于其中,主要矿脉有72条,矿脉总 There has been nearly 40 years of mining history in the Emeai Au mining area. During the period from the sixth mining to the sixth in the 1960s, there was obvious pressure-pressure activity. Especially in the vicinity of the F_1 trunk crust, the deeper the underground pressure-pressing activities are more and more frequent . In 1979, we investigated and studied the ground pressure and geologic structure of the thrush Au ore belt. The details are as follows: I. Mining and Geological Survey The Thmeau Au mine is located in the mountainous area at the junction of Xingguo and Ningdu counties. The terrain is North East and Southwest low, the lowest point of 520 meters. According to lithology identification, the strata are divided into five layers from top to bottom, mainly consisting of quartz mica schist, mica quartz schist and metamorphic quartz sandstone, including Tungsten beryllium thin quartz vein group is produced in which the main veins are 72, the total veins
