1、DEVELOPING OF TRANS-CENTURY MINING SUBJECTWITH NEW TECHNOLOGY AND NEW THEORYAbstract： Mining subject needs further development and towards which the development would being the problems concerned over all along and to be succeeded with the public good enough attention to discussions to reach an iden

The emergence in succession of new-and-high techs in the mid-and late twentieth century is perhaps the most fascinating and epoch-marking event that has given to all the subjects certain but different degrees of impacts to become more closely interrelative and interdepartme

The words Science and Technology being the First Production Force has fatherly and penetratingly pointed out the important role of new technology in the course of national economy construction.In the competition of several big countries in the world striving for the exploratio

To assure the survival of mankind on the earth，four essential requirements should be considerably fulfilled，namely，the nutrients，materials，fuels and the environment. The nutrie

The materials refer to iron，ferrous metals，rare metals，precious metals，chemical raw materials and building materials. The fuels cover coal，petroleum，natural gas ，oil shale，uranium，thorium and

In the above three essential substances，the materials and fuels are through mining engineering extract from bining industry is a conventional industry， however，with th

As long as mankind live on the earth，mining industry will last forever and never decline and fall，instead，as mans living demands increases，the output of fuels and raw materials

Since mining industry is closely related with geology， metallurgical and energy industry consequently in the subject relationships，they are interrelative and interdepartmental each other. As mining subject branch of science dealing with th
