Abstract：Because that the coal-fired power plants need to formulate sampling scheme plan of coal as fired according to its own combustion features and sampling machine performance,the formulating and adjusting of sampling plans were discussed from aspects such as primary increment variance,number of increment of sampling unit,sampling scheme adjustment and sampling of total moisture.It is pointed out that attention should be paid to work of checking the sampling precision and sampling scheme should be adjusted in time according to the requirements of primary increment variance and the number of minimum increment.
