Abstract
Taking the tuff in Lancang Lead Mine in Yunnan as an example, pure tuff most typical therein is selected to carry out indoor water-disintegration test and then to analyze change of the particle size distribution in this process. The content change of the particle in respect of which the diameter is more than 5. 00 mm or less than 0. 28 mm in the disintegrated rock is taken as the object of assessment, then through comparative analysis, relation between the performance and rate of the disintegration and the time and mass is explored. The experimental study result shows that tuff in same mass has increasing rate of disintegration as the increase of soaking time; and under same time, the rate of disintegration increases with the increase of tuff mass.关键词
