Coal burning deep underground in China, India and Indonesia is threatening the environment and human life, scientists have warned. These large scale___________ (51)blazes (火焰)cause the ground temperature to heat up and kill surrounding vegetation,produce greenhouse gases and can___________ (52) ignite (点燃)forest fires,a group of scientists told the annual meeting of the American Association for the Advancement of Science in Denver.

The members of the panel discussed the____________ (61) these fires may be having on global and regional climate change, and agreed that the underground nature of the fires makes them difficult to___________ (62).
Ultimately, the remote sensing and other techniques should allow scientists to___________ (63) how much carbon dioxide these fires are emitting (释放).One suggested___________ (64) of containing the fires was presented by Gary Colaizzi, of the engineering firm Goodson,which has developed a heat-resistant grout (灌浆),which is designed to be pumped into the coal fire to____________ (65) the oxygen supply.
