摘　　要：以"安全高效低成本低贫损"为原则,在深入研究与实践的基础上,主要对水平分层采矿法与垂直分条采矿法在缓倾斜薄矿体采矿活动中的实践应用做了系统分析和总结,通过对采切工程的布置,采场生产能力,材料消耗,两率指标等方面的比较论证,得出了垂直分条采矿法具有工人作业强度小,安全系数高;采场生产能力大,回采工效高;采切工程量小,经济效益显著;损失贫化率低等一系列优点。从而验证了垂直分条采矿法用于围岩稳固的缓倾斜薄矿体,是一种优势明显、切实可行的采矿方法。Based on penetrate into study and practice,the paper systematically analyzed and summarized the application of horizontal sublevel mining method and perpendicular substreak mining method in the mining of gentle dip thin orebody on the principles of safety,high benefit,low cost,low loss rate. and low poverty rate. According to compare proof by arranged mining and incise engineering,mining ground produced capability,consumed material,the target of loss rate and poverty rate,we draw the conclusion that perpendicular substreak mining have a series of advantage,such as smaller the worker labor intensity,high safe coefficient,bigger the mining ground capability,higher mining efficiency,smaller the mining and incise engineering amount,very remarkable economic benefit,lower the loss rate and poverty rate etc. Thereby,it is verified that the method is a efficacious mining with obvious superiority for the gentle dip thin orebody in the stable wall rocks.
