湘潭锰矿是我国较大型的锰矿基地之一。已闭坑的一期区(石塘坳、彦家冲、曾家塘井区)曾沿用崩落法开采,崩后围岩的自燃内因火灾,以及地下水的威胁,加上地面不允许崩落,是生产中的突出问题。因此,二期区(红旗井区)改用了水砂充填法开采。自一九六九年投产以来,经十多年的生产实践,技术上不断改进完善,使水砂充填法开采湘锰复杂地质条件的矿床日相适应。本文
Xiangtan manganese ore is one of the larger manganese base in China. The first phase of the closed pit (Shek Tong Au, Yan Ka Chong and Zengjiangtang) had been exploited by caving method. The internal spontaneous combustion of surrounding rock after the collapse and the threat of groundwater, together with the intrusion of the ground, are not allowed Outstanding problems in production. Therefore, the second phase (Hongqi well) to use water sand filling method mining. Since it was put into production in 1969, after more than 10 years of production practice, its technology has been continuously improved and perfected, which has made it possible to adapt the ore bed for mining the complex geological conditions of Xiangtan with water sand filling method.
