摘　　要：针对目前瓦斯地质工作存在的问题,提出通过信息化程序开发,以更准确地进行瓦斯地质图编制。利用克里金法实现地面标高和煤层底板标高两个面的网格化,求差值得出埋深面,优于插值法;建立瓦斯含量多元拟合模型并绘制成图,解释瓦斯赋存的多因素控制作用,比单因素模型更具科学性;在体积法计算瓦斯储量时,采用微积分算法,可减少各区块平均值计算误差;动态瓦斯地质图可实现增加有效新测点后模型自动修正和图形自动更新,加强瓦斯地质图时效性;瓦斯地质图同步跟踪采掘进度,实现对已知构造预警和未知构造连续信息判识。To counter to the problems present in the coal-bed gas geology work, the information program development technology was proposed for accurately preparing the geological map of coal-bed gas. Kriging method was used to achieve the gridding of two surfaces of ground elevation and seam floor elevation and the buried depth surface was obtained by calculation, which was better than the interpolation method; a multivariate fitting model of gas content was established and mapped out for explaining the control action of multifactor in gas occurrence, which was more scientific than the single-factor model; in the calculation of gas reserve with volume method, using calculus algorithm can reduce the calculation error of the average values of each block;using the geological map of dynamic gas can achieve the automatic correction of the model and the automatic update of graphics after the increase of the new effective measuring points and strengthen the timeliness of the geological map of coal-bed gas;the geological map of coal-bed gas can be used to synchronously track the progress of the preparation and mining work and realize the early warning of known structures and the judgment and recognition of the continuous information of unknown structures.
