印度的能源需求不断增长。煤炭是印度的主要化石燃料，并继续在能源部门发挥关键作用。与原油（7.28亿吨）和天然气（6860亿立方米）相比，印度的煤炭储量（2530亿吨）相对较大。煤炭满足了约60%的商业能源需求，印度生产的约70%的电力来自煤炭，因此需要有效和清洁地利用煤炭的技术。与传统的采矿和气化工艺相比，UCG具有许多优点。超声心动图是一项成熟的技术。由于这一过程的场地特性、地面沉降和周围含水层水污染的可能性，这项技术在印度仍处于发展阶段。通过比较印度煤的性质与各种UCG试验所利用的煤的性质，研究了印度UCG的潜力。根据世界各地成功进行的现场试验报告的信息，阐述了在印度启动UCG的基本问题。印度工业界正在各个地点开始进行地下化学品生产的试点研究。这项研究将有助于推动印度UCG场地的应用和理论研究工作，并在详细分析后为感兴趣的行业提供基本数据。(C)2007爱思唯尔有限公司保留所有权利。
Energy demand of India is continuously increasing. Coal is the major fossil fuel in India and continues to play a pivotal role in the energy sector. India has relatively large reserves of coal (253 billion tonnes) compared to crude oil (728 million tonnes) and natural gas (686 billion cubic meters). Coal meets about 60% of the commercial energy needs and about 70% of the electricity produced in India comes from coal, and therefore there is a need for technologies for utilization of coals efficiently and cleanly. UCG offers many advantages over the conventional mining and gasification process. UCG is a well proven technology. Due to the site-specific nature of the process, possibility of land subsidence and surrounding aquifer water contamination, this technology is still in a developing stage in India. Potential for UCG in India is studied by comparing the properties of Indian coals with the properties of coal that are utilized by various UCG trials. The essential issues are elaborated for starting UCG in India based on the reported information from the successful field trials conducted all over the world. Indian industries are in the process of initiating pilot studies of UCG at various sites. This study will help to motivate both applied and theoretical research work on UCG sites in India and after detailed analysis it will provide basic data to interested industries.
