Coal slurry pipelines with large pipes buried in the ground covers an area of less capacity is not affected by climate condition of complex topography and adaptable airtight do not pollute the environment of long-distance transportation freight cost low and easy to implement all the advantages of automatic control, is an effective way of coal transportation, has been promoted after the 1950 s, long distance slurry pipeline transportation implements the commercialized multinational has related history, the United States of Ohio coal slurry pipeline 174 km in diameter 254 mm long coal 1.3 million t run successfully in 1957 and 1963, the American black Wallace (Black Mesa) Coal slurry pipeline with a length of 439km and a diameter of 457mm carries 4.8 million tons of coal annually. Since 1970, it is still in normal operation. Russia has built a 2600km coal slurry pipeline with a diameter of 529mm and a yearly coal conveying of 3 million tons in Siberia。
China has conducted ZhunGeEr qinhuangdao southeast shanxi nantong Yu County shenmu port of Qingdao and weifang Bin County xianyang distance coal conveying pipelines such as feasibility study through efforts, conventional slurry has after 94 hours of uninterrupted transmission, already from god nutrient-laden starting depot shaanxi shenmu coal conveying pipe flow, which means that the world's largest Chinese the first long distance conveying pipeline project charge commissioning are expected to complete all this slurry pipe line transmission plant capacity up to 10 million tons, the future pipeline will walk more, go further, its importance for power plant boiler Industrial boilers and kilns replace oil-gas coal combustion, hotels, residential buildings, office buildings and other buildings with heating and domestic hot water with long-term benefits. Under the guarantee of China's rich coal resources, coal water slurry has also become the most basic and economical clean energy to replace oil-gas energy。
