摘　　要：随着矿业生产变革,矿山采矿方法随之有了巨大的变化,从上个世纪五六十年代的小型规模的开采,到现代的大型矿山开采。采矿能力从日产30~40t,增加到日产500~1 000t,对于厚大急倾斜矿体采用传统的浅孔留矿法到现在已成熟的大直径深孔采矿法。With the change of mining production and mining methods have followed with great changes,from small- scale mining of the fifties and sixties of the last century,modern large- scale mining,mining methods have great changes,ore block ability from Nissan 30 tons,increased to Nissan200 ~ 300 tons,the thick steeply inclined orebody with traditional shallow hole shrinkage stoping up to now to the maturity of the large diameter longhole mining method.
