高寒地区采矿实践

Mining Practice in Alpine Region

高寒地区缺氧,气压和水的沸点低,人的工作能力也因之下降,设备在这种地区运转效率低,使用寿命短。根据高寒地区的特点,在西藏自治区某铅锌矿的采矿实践中,采用了分条采矿法方案,使用浅孔凿岩, 2#岩石炸药爆破,手推车出矿,取得了较好的效果。

In alpine region, the labour ability of human lowers because of oxygen deficiency, low atmospheric pressure and boiling point of water, as well as the running efficiency of equipments is lower, the service life of equipments is short. In light of the characteristics of alpine region, strip stoping method was adopted, which ore was blasted with sort-hole and No.2 rock explosive as well as the broken ore was transported by wheelbarrow, during the mining practice in Tibetan autonomous region, and good mining results had been achieved.
