摘　　要：利用选煤厂的月综合试验报表,结合产品计量统计数据,可以得到较准确的原生煤泥量、总煤泥量、次生煤泥量数据,但我国相当一部分选煤厂没有开展月综合试验。为了快速准确地得到选煤厂的次生煤泥量,通过对原煤、产品计量与湿法筛分脱泥方法获取次生煤泥量的可行性进行探索,并以梗阳选煤厂为例,简要介绍该方法的测试内容和计算步骤、测试结果。Generally,a relatively accurate quantity data of primary slime and secondary slime as their aggregate figure can readily be made known by reference to the plant＇s monthly consolidated test report and the statistical data of quantities of products. However,quite a number of the plants in China has never conducted any monthly comprehensive test work. In order to determine the volume of secondary slimes generated in coal preparation plant in a rapid and accurate manner,test work is made on the feasibility to determine the volume of secondary slime through weighing raw coal,cleaned products and the products of desliming screen. A brief introduction is made in the paper to the testing items,calculation procedures and result obtained at Gengyang coal preparation plant which is cited by way of example.
