RESEARCH ON FEASIBILITY OF MECHANIZED MINING OF COAL-BEARING HARD KAOLIN IN CHINA

In the case of continuously raising of the requirements of Kaolin and the sale prices at present,the mining output of Kaolin,however,is hard to improve.The article aims at the study of choke point restricting the outputs of Kaolin-the backward of mining technology,including the low efficiency of breaking rock and mechanized shipping,the backward of supporting and so on.The study indicates that the adoption of rational mechanized equipments can make the productions be safe,high efficient and in great scale,and it can also bring well economical benefits.The innovative technics fills a vacancy of mechanized mining technics in the field of underground Kaolin ore in China.It creates a good condition for safe mining of coal-bearing Kaolin effectively.
