煤岩瓦斯动力灾害主控地质体理论及地质作用机理
Main controlling geological body theory and geological effect mechanisms of coal and gas dynamic disaster
摘要
Abstract
In order to study coal and gas dynamic disaster geological effect mechanisms,the concept,def-inition and classification of main controlling geological body for coal and gas dynamic disaster were firstly put forward,and the geological effect mechanisms were studied through theoretical analysis,laboratory experiment and field measurement. The results show that coal and gas dynamic disaster geological effect mechanisms indicate that the coal seam thickness and top and floor lithology and particle size and occur-rence status and etc. are controlled by sedimentary system and sequence stratigraphy of coal measure strata,and the closer coal seams to the sea( Lake) flooding surface position of the ( lake) transgressive system tract,the more coal seam gas( except for coal seams with limestone roof and floor) ,and the more dangerous coal seam gas dynanic disasters will be. Coal and gas danger degree differences in the same coal seam group were explained;coal and gas dynamic disaster geological effect mechanisms indicate that coal seam transformation degree,gas generation,storage and dissipation degree,gravity stress and tecton-ic stress distribution and the regional distribution and disaster degree of coal rock and gas dynanic disas-ter are controlled by spatial-temporal collocation of strata sedimentary buried and geological tectonism and thermal evolution effect and hydrocarbon generation etc. The theory and analysis methods and deci-sion rules of main controlling geological bodies are preliminarily established. The research results are ap-plied in Shuicheng mining area,and the rationality and applicability are verified.关键词
