摘要
从采矿方法选择的原则出发,介绍了澜沧老厂铅矿采矿方法从不适应到逐步适应,从不完善到逐步完善的艰难发展历程。重点讲述了小分段崩落采矿法的工艺及其特点,针对开采中暴露出的问题,经过认真研究比较,对现在的小分段崩落采矿法进行改进,优化工艺参数,配备使用出矿设备,取得了比较好的经济和技术效果。
The introduction of the difficult method development of Lanchang Laochang lead ore mining from inadaptation to acc- limitization, from imperfection to gradual improvement. The process and features of subsection caving mining method is focused introduced, according to the exposed problems in mining, through the conscientiously study and comparison, the improvement of subsection caving min- ing method is carried out, the process parameters are optimized, the equipped mining devices get the better economic and techical effect.
