我矿已勘探地区的标高在1600—3700米之間,地形陡峻,峽谷高山,矿体傾斜,大部份为60°～80°(賦存于灯影白云岩底部的矿体除外),适于采用平坑进行詳細勘探。其深部和灯影白云岩底部的矿体則宜于用鑽探。截至58年底共完成勘探坑道212,880米(小水平坑除外),岩心鑽探87,512米。勘探阶段,由于布置探矿坑道时結合考虑了将来生产的利用,以后,在矿井設计中也充分利用了原有的勘探坑道,因而,仅仅用了一年左右的建矿时間,第一期两个矿山則将投入生产。现将其中一个矿山利用原有勘探坑道的情况介紹如下。該矿由五个矿段組成,标高在2400—3000米之
The elevation of the mine which has been explored in the area between 1600 and 3700 meters, the steep terrain, canyon mountains, ore body tilt, most of the 60 ° ~ 80 ° (except for the ore body that occurs in the bottom of the lamp shadow dolomite), suitable Flat pit for detailed exploration. Its deep and light shadow dolomite at the bottom of the ore is suitable for drilling. By the end of 582, a total of 212,880 exploration tunnels were completed (except for small horizontal pits) and core drilling was 87,512 meters. Exploration stage, due to the arrangement of prospecting tunnel combined with the consideration of the future production, after the design of the mine also make full use of the original exploration tunnel, therefore, only spent about a year of construction time, the first phase Two mines will be put into production. Now one of the mines to use the original exploration tunnel situation is as follows. The mine consists of five ore sections, elevation of 2400-3000 meters
