摘要: 盘古山钨矿地压问题在我国脉钨矿山中具有典型的代表性。该矿20世纪90年代中后期开始,随着开采深度的加大和矿山资源消耗较快,为弥补资源不足和生产能力的下降,开始进行矿柱和残留矿体的回收,加上充填欠帐,由此引发系列地压问题。文章通过对盘古山钨矿地压现状调查、分析,提出了矿山地压控制措施。Abstract: The ground pressure in Pangushan mining area is representive in vein tungsten mines in our country. From middie of the 1990s, mining is deepen and remnant piiiars stoping is done to remendy the resources and production capacity, and series of ground pressures are caused because bashing is imperfected.
