目前用于矿石中等稳固中厚矿体,且矿体倾角<40~45°的采矿方法,普遍存在着矿石的损失、贫化大或劳动生产率较低的弊病。为此,最近有人在模拟试验研究的基础上,提出了爆力运矿连续采矿法(中南矿冶学院周骥“爆力运矿连续采矿法的探讨”)。所谓爆力运矿就是利用炸药爆炸后的抛掷力,将崩下的矿石抛掷到预定的堑沟中。因此,
At present, the mining methods used for medium stable and moderately thick ore bodies with ore body inclination of <40-45 ° generally have the drawbacks of ore loss, depletion or low labor productivity. To this end, some people recently based on the simulation test study, proposed a continuous blasting ore transport method (Central South Mining and Metallurgy Institute Zhou Ji “blasting ore transport continuous mining method”). The so-called explosive power mine is the use of explosives thrown after the thrown force, the collapse of the ore thrown into the predetermined trenches. therefore,
