摘　　要：煤炭地下气化技术是抛弃了全部庞大的、笨重的采煤设备与地面气化设备,并将传统的地面气化转化为地下有控制的气化新技术。其具有安全性好、投资少、效率高、污染小、效益高等优点。为了使煤的燃烧和气化得到有效的控制,监测燃烧区的范围和火焰工作面移动速度是致关重要的。在分析了测氡法应用于确定燃烧区范围和移动速度可行性的基础上,本文提出了采用测氡法对急倾斜煤层中煤炭地下气化燃烧区范围和移动速度进行监测的有益探索。现场试验研究表明,该方法能够较好地探测燃烧区的范围和移动速度。All of mining and ground gasification equipment are abandoned for technology of underground coal gasification（ UCG）, and traditional ground gasification is converted to underground controlled gasification. UCG has advantages of good safety, less investment, great effect, less pollution, and high benefit. For the controlling of gasification and combustion of coal, it is very important to survey combusted zone and velocity. On basis of feasible analysis by radon-measurement method, radon-measurement method is applied for the detection of combusted zone and velocity of UCG in steep coal layer. In field-test, combusted zone and velocity can be effectively detected by this method.
