摘　　要：优化崩矿步距的原则,可归结为使放出体的上部形态与残留体和崩落体总体边界相符。本文通过试验的方法确定了弓长岭井下矿放出体、残留体基本形态,又通过现场标定出矿过程中废石混入的时间与混入率,推断出崩落体的基本形态,确定了相应采场结构下崩矿步距的合理值。The principle of independent advance of ore breaking is the top shape of drawn-out ore body keeping with the shape of left ore and caved ore body. In this article ascertain the shape of left ore and caved ore body, ascertain the shape of caved ore body with confirming the time of waste in-ore and waste in-ore rate. Optimization of the independent advance of ore breaking.
