露天边坡煤炭地下气化工业性试验研究

Study on field test of underground coal gasification on the side of strip mine

针对“三下”煤层,难采煤层,复杂煤层以及露天边坡剩余的煤炭资源,井工开采不经济或难以开采,可利用煤炭地下气化将这些殘余资源得以回收利用,试验利用矿井式煤炭地下气化方式,对阜新矿露天边坡进行了空气煤气、水煤气、富氧煤气的工业性试验研究,通过煤炭地下气化工业性试验,得出在露天边坡矿井式气化建炉方式,不同气化工艺的煤气组分,热值.露天边坡的高挥发性、复合薄煤层适合于用地下气化技术生产中、低热值煤气,气化剂不同,其热值不同,用途不同。

Aiming at the coal under the building ,rail and water, difficultly- mined coal and the side of strip mine, hardly mined ,but it is utilization for the UCG study on field test of air coal gas, water coal gas, rich oxygen coal on the side of strip the side of strip mine mine of Fu Xin ,Using the UCG for the mineral well, getting the method for building stove of UCG, obtain different coal gas group and heat value for the different gasification craft high volatile, multiple thin coal seams on the side of strip mine are suitable to underground coal gasification to produce middle low heat value gas. Different gasification agent produces different heat value gas with different use.
