水口山铅锌矿是水口山矿务局目前铅锌原矿生产基地,迄今已有90年的历史。由于地质资源日趋枯竭,又存在较大的地下水,一般水量为800～1000吨/时,是一个“锅大、水多、米少”的老矿。而在有限的可采矿量和远景矿量中,又存在含硫高(共生硫平均品位在20％以上)、温度高(采场炮孔温度高达36℃)、矿石氧化率高(20～30％)、自爆因素大的矿体。1982年元月在开采一号矿体时,曾发生过
The Shuikoushan lead-zinc mine is the current lead-zinc ore production base of the Shuikoushan Mining Administration, which has been 90 years of history. Due to the depletion of geological resources and the existence of larger groundwater, the average amount of water is 800-1000 tons per hour, which is an old mine with “large pots, more water and less rice”. In the limited amount of mining and prospect ore, there are high sulfur content (symbiotic sulfur average grade above 20%), high temperature (blasthole temperature up to 36 ℃), ore oxidation rate (20 ~ 30 %), Blasting large ore body. January 1982 Occurred in the mining of No. 1 ore body, had occurred
