【摘要】 针对川口钨矿杨林坳矿区难采矿体的开采技术条件，经优选采用爆力运搬阶段矿房采矿法，成功地解决了该矿区占总工业储量６０％以上（质量分数）的倾斜、中厚、多层、低品位难采矿体的开采方法，也为其它矿山同类型矿体开采提供了科学技术依据和工艺经验。更多还原

【Abstract】 According to the mining conditions of difficult grounds in Yangjiaao district of Chuank-ou tungsten mine,the paper proposed some main principles of determining the miningmethod of these difficult ore bodies,which accounts for 60%total ore reserve in the district.Using the principles,authors designed and tested successfully a special mining method suit-able to the layered ore bodies with the oblique angles of 30°～45°and medium thickness,thatis,block stopping method of moving ore by blasting power.It is estimated that this miningmethod can be applied to other mines with the similar ore bodies.更多还原
