苏联学者Я.И.巴尔巴恰恩教授在1946年就提出了远距离水力有压运煤的计划;同年,法国的C.M.萨巴提尔提出对矿山所采出的煤炭及矿石的水力运输设计的专利权.此后不久(1848～1850年),在其他国家也开始加强对水力有压运煤问题的研究.在美国有皮茨堡统一煤业公司建立一个用直径300公厘的管道远距离运煤5公里的研究站.还有其他一些机关(西屋公司、标准石油公司、矿井局等)从事水力运输的研究工作.在英国有不列颠水力机械化研究院进行水力运输的研究.
Soviet scholar Я.И. Professor Barbaban put forward a plan for long-distance hydraulic coal with pressure in 1946. In the same year, CM Sabatier of France proposed the design of hydraulic transportation of coal and ore taken by mines (1848 ~ 1850), and other countries began to intensify their research on the problem of hydraulically-pressurized coal transportation.In the United States, Pittsburgh’s unified coal mining company established a pipeline with a diameter of 300 mm long There is also a number of other agencies (Westinghouse, Standard Oil, Mine Bureaus, etc.) that are engaged in research on hydraulic transport, and has a British Hydro-mechanized Research Institute for hydraulic transport research.
