摘要
本研究提出的采矿方法,是开采中厚倾斜难采矿体的一种新型有效方法之一。这种方法具有结构简单,工艺先进,贫化损失少等突出优点。并实现了单步骤连续回采,从而进一步提高了开采强度和生产效率。本方案经过工业试验检验,获得良好的技术经济指标。在试验期间,获得的经济效益为140万元,社会经济效益为370万元,可在中厚倾斜矿体中广泛推广使用。
The mining method described in this paper is one of the new efficient methods for mining
inclined medium thick ore body.This method has the outstanding advantages of simple
structure,advanced technology,low dilution and loss.With the realization of one step
continuous mining,the intensity of mining and the efficiency of production have been greatly
increased.
The method was tested by industrial experiments,and good technical and economic results
were obtained,including 1.4 million yuan direct economic benefit and 3.7 million yuan social
economic benefit.This method can be widely applied in the inclined medium thick ore body.
