水口山铅锌矿是一个有九十年开采历史的老矿山,解放后就开采了近500万吨矿石量。随着生产的发展,矿山开采由老鸦巢生产区扩大到了鸭公塘生产区。由浅部扩展到了深部(老区-300米以下,西区-200米以下),随之出现的重大问题是:矿山铅锌矿石可采矿量不足;原矿品位下降;新、老空区未及时充填;潜在着严重的地压活动。仅以鸭公塘生产区而言,七个中段八个矿体,其中矿石量占整
Shushan Mountain lead-zinc mine is a 90-year-old mining history of the mine, after the liberation of mining nearly 5 million tons of ore. With the development of production, mining has been expanded from the Laoscao production area to the Duogang Tang production area. From shallow to deep (old area -300 meters below the western region -200 meters below), followed by the major problems are: mining lead-zinc ore mining capacity is not enough; ore grade decline; new, empty area is not timely filling; potential A serious ground pressure activities. In the area of Yaogangtang Production Area alone, there are eight ore bodies in the middle seven sections, of which the ore volume is the largest
