盘古山钨矿属高温热液裂隙充填钨、铋石英脉状矿床。用浅孔留矿法开采,目前采深500米。1967年以前采空场未做处理,矿区在1966年、1967年相继发生二次大规模的地压活动,地表以下六个中段发生岩层移动,造成巨大损失,此后小规模的地压活动也不断,严重影响生产的发展。随开采延深,掌 Panguoshan tungsten ore is a high-temperature hydrothermal fissure filling tungsten, bismuth vein vein deposits. Mining shallow mining method, the current mining depth of 500 meters. Before 1967, the mined-out area was not treated. There were two large-scale underground pressure activities in succession in 1966 and 1967, and the rock movement occurred in the middle six sub-areas of the earth surface, resulting in huge losses. Since then, small-scale underground pressure activities have also continued , Seriously affecting the development of production. With the mining deepening, palm
