门捷列夫百余年前提出的煤炭地下气化技术的设想,在我国取得突破性进展。中国矿大煤炭地下气化研究中心与徐州矿务局合作,于1994年11月9日获得的地下煤气每立方米热值高达3000千卡以上,成本仅0.15元/m~3,大大超过了国际上已研究了40余年的地下气化使用纯氧与水蒸汽作气化剂时生成2000千卡热值煤气的水平。这一巨大成就的取得,得益于他们首创和应用了长通道大断面两阶段煤炭地下气化新工艺。 一般来说,井工矿仅能开采出50％左右煤炭,还有一半煤炭资源残留在地下。课题组以衰老和报废煤矿为对象,首先在徐州矿务局新河二号井(现更名为卧牛山煤矿)的残留煤柱中,开掘断面为2.5m~2的

Mendeleev over 100 years ago put forward the idea of ​​underground coal gasification technology in our country made a breakthrough. In cooperation with Xuzhou Mining Bureau, China Coal Mine Underground Gasification Research Center, on November 9, 1994, obtained more than 3,000 kcal / cubic meter of underground gas at a cost of only 0.15 yuan / m ~ 3, which greatly exceeded Internationally, more than 40 years of underground gasification have been studied using pure oxygen and steam as gasifiers to generate 2,000 kcal calorific value gas. This tremendous achievement has been attributed to their pioneering and applied new technology for two-stage underground coal gasification with long channels and large sections. In general, wells and mines can only produce about 50% of the coal, and half of the remaining coal resources in the ground. Task group to the aging and scrapped coal mines for the object, first in the Xuzhou Bureau of Mines Xinhe No. 2 (now renamed the Wusiu Shan Coal Mine) residual pillars, dig section 2.5m ~ 2
