                    大块率控制是地下开采浅孔爆破落矿的一个技术难点。结合南温河钨矿生产实际,对地下开采浅孔爆破落矿中大块产生的原因进行了分析,并提出了相应的降低大块率的改进技术,在实践中取得了良好的效果,解决了南温河钨矿采矿过程中大块率居高不下的难题,对类似矿山具有一定的借鉴意义。
                
                It is a technical challenge to reduce boulder yield from shallow-hole blasting in underground mining.The paper took the production practice in Nanwenhe Tungsten Mine as the research subject,analyzed the cause of boulder yield from shallow-hole blasting in underground mining and put forward countermeasures to reduce the boulder yield.The techniques performed well in reducing the excessive boulder yield in the mining process in Nanwenhe Tungsten Mine and can be used as reference by similar mines.
