-
摘要: 叙述了平洞溜井运输经济性的原理和实质，提出了13项平洞溜井经济指标体系。并以攀钢矿山12条溜井为工程实例，论证了对这些溜井系统进行挖掘、改造的途径。认为通过挖掘、改造后，可以增大通过溜井运输的矿岩量，延长平洞、溜井的服务年限，提高矿山开采的经济效益。Abstract: Economical principle of the drift-orepass transportation is explained and thirteen economical indexes of drift-orepass are proposed.The ways to modify these passes are demonstrated as the examples of twelve Pangang mine passes.It is considered that the increment of ore and rock transportation volume throughout passes, the extension of service life of adits and passes and the improvement of economical benefits to mining can be achieved by means of modification.
