Abstract
From three geological factors of sedimentation , structure and hydrogeology condition , CBM occurrence character-istics of Wayaobu Formation coal-bearing strata in Yuantungou minefield of Zichang mining area were discussed .The results show that the gas generating capacity of Wayaobu Formation strata is low because of variable sedimentary environment , little coal forming scale and thin total thickness of coal seams , gas storage capacity is low due to undeveloped sealing structure and thin thickness of effective cover layer , and the reservoir pressure is low which reduced the gas accumulation because of weak water yield property .关键词
