摘要
矿岩二次破碎是矿山重要的生产环节。分析了采用爆破法和采用碎石器进行二次破岩的利和弊,提出了采用液压劈岩机进行二次破岩的新方法,并对这种新的破岩方法的特点进行了论证,认为这是一种安全、投资少、经济效益高的二次破碎方案。
Secondary rock breaking is important production link in mines. The advantages and disadvantages of secondary rock breaking with blasting method and with rock breaker was analysed. Then a new secondary rock breaking method by using hydraulic splitters was put forward. And the advantages and characteristics of the new rock breaking method was demonstrated. It is considered that it is a fine scheme with safety, lower investment and higher economic benefit for secondary rock crushing.
