The frequent coal shortages have widely aroused attention to the construction of coal reserve system, some coal reserve bases have been established in many provinces. But researches are few on site selection and scale measurement. With references to the researches on oil reserves, the paper first explored the influential factors on the site selection of regional coal reserves, taking Jiangsu Province as an example, three coal reserve bases should be built in Nanjing, Xuzhou and Lianyungang to ensure the coal supply. Then, learning from the researches on coal resources reserves and grain reserves, a general approach to calculate the scale of regional coal reserves was given, then, taking the direct-supply power plant in Jiangsu as an example, the scale of coal reserves were est imated with the fluctuation range of stock volatility (0, 0), ( 1 % , -1 % ), ( 5 % , -5 % ), ( 10 % , -10 % ), suggesting that the biggest dynamic reserves of 301,800 tons be moderate, with the fluctuation range of stock volatility ( 5 % , -5 % ). The research has important significance to promote the construction of regional coal reserve system.
