Characteristics of Geostress and Its Impact on the Development of Coalbed Methane in Hancheng Mining Area
摘要
Abstract
Based on the practical production data of Hancheng mining area, this article discusses the distribution characteristics of geostress and its impact on coalbed methane development by mathematical calculation method. The study found the value of minimum horizontal stress is generally greater in the west than the east on the trans-verse,while the longitudinal stress value tends to reduce first and then increase.With the increase of geostress,the coal structure changed from fragmentation coal to mylonite coal,and the coal reservoir permeability decreases.The coefficient of horizontal principal stress difference is literally less than 0.47,and the production increases with coef-ficient increasing.Geostress contour map is in accordance with the coalbed methane gas production contour map.关键词
