Title:
METHOD FOR ASSESSING SUITABILITY OF CARRYING OUT UNDERGROUND COAL GASIFICATION ENGINEERING BY USING DEEP COAL SEAM
Document Type and Number:
WIPO Patent Application WO/2024/087544
Kind Code:
A1
Abstract:
A method for assessing the suitability of carrying out underground coal gasification engineering by using a deep coal seam. The method comprises: acquiring a basic geological condition, an engineering geological issue, a hydrogeological condition, the mass of contained coal, the situation of a deep coal seam, and unit-coal-gasification heat and synthesis gas components of a deep coal seam area, so as to obtain scores for corresponding influence factors; according to the score for each influence factor of the deep coal seam, determining influence indexes of an influence factor of the geological condition and engineering geology, an influence factor of the hydrogeological condition, an influence factor of the mass of the coal, an influence factor of the situation of the coal seam, and an influence factor of the unit-coal-gasification heat and synthesis gas components; and determining a comprehensive influence index on the basis of the influence index of each influence factor of the deep coal seam, and according to the comprehensive influence index, determining the suitability of carrying out underground coal gasification engineering by using the deep coal seam.
