摘　　要：本文针对主动式测定煤层瓦斯压力的特点,主要分析在补气和不补气条件下钻孔周围瓦斯流动规律,以使钻孔内和钻孔周围瓦斯压力尽快达到平衡为目标函数,求解理想状态下的最佳补气压力。并通过现场试验对求解结果进行检验,为实际测定煤层瓦斯压力提供理论和实际依据。According to characteristics of the active measurement of gas pressure in coal seam, this paper analyzes the methane flow regularity around borehole at the conditions of supply air or not. So that let the gas pressure in and around drilling to achieve balance as soon as possible as the objective function, and solve the best air supplement pressure in ideal state. Using the field test check the solving result, all this can provide theoretical and practical basis for actual d measurement of seal gas pressure.
