【摘要】 采用分层崩落法对木利锑矿主矿体进行回采,存在地表陷落、机械化程度低、贫化率较大、通风条件差和坑木消耗大等问题。针对以上问题,设计采用了上向分层进路充填采矿法对主矿体进行回采,并在矿山进行了采矿实践,结果表明该采矿方法可克服以上缺点,获得了较好的经济效益,对同类矿山的生产具有一定的指导意义。更多还原

【Abstract】 When using stratified caving to extract the main ore body in Muli Antimony Mine,problems as surface fall,low level of mechanization,high dilution rate,poor ventilation and large timber consumption may occur.To solve these problems,a new design of upward layer filling method was adopted.Mining practice showed that the method overcame those shortcomings and obtained better economic benefits.It is of great significance to the production of other similar mines.更多还原
