【摘要】 煤的地面气化运输成本高,且污染环境,而地下直接气化又难以控制。针对这些问题,提出将地面煤气化厂的气化锅炉等主要设备设置到煤矿井下,将采出的煤在井下气化后,通过管道将煤气输送到地面的设想,并就这一设想的可行性和可能遇到的问题作了一些粗略的探讨。更多还原

【Abstract】 The coal gasification on earth surface causes the high cost of transportation and environmental pollution, and yet the in-situ coal gasification in underground is difficult to be controlled. In light of these problems, author advances the idea that the main equipments such as gasification boiler are installed in underground to construct underground coal gasification plant at a mine, the caved coal is gasified in the underground gasification plant, and produced coal gas is transported to surface in pipe. This paper makes a rough approach to the feasibility and possible problems about the idea.更多还原
