【摘要】 煤炭地下气化可以从根本上消除煤炭开采的地下作业工程 ,充分利用煤炭资源 ,将煤层所含的能量以洁净气体的形式输出地面 ,而将灰烬和废渣留于地下 ,从而大大减轻传统采煤和气化工艺对环境造成的不良影响。为了使地下煤层的燃烧和气化得到有效的控制 ,使气化工艺有效地发挥作用 ,及时准确地了解地下气化状态 (包括燃烧工作面的位置、移动速度及燃空区的范围等 )至关重要。监测试验表明 ,综合电磁法是进行煤炭地下气化监测的有效方法。更多还原

【Abstract】 An underground coal gasification can eliminate an underground coal mining operation. The gasification can fully utilize the coal resources and can transport the clean gas to the surface and leave coal residue in the underground mine. Therefore the gasification can highly reduce the bad influences to the environment caused by the traditional coal mining and fraditional coal gasification processes. To have an effective control to the combustion and gasification of the underground coal seam and to have a effective function of the gasification, it is important to timely and correctly understand the underground gasification status, including the location of the combustion face, moving speed, area of the after combustion and others. The monitoring and measuring results showed the comprehensive electric magnetic method is an effective method to monitor and measure the coal underground gasification.更多还原
