摘　　要：以矿井通风系统图为依据,利用Auto CAD VBA开发可视化窗体,通过建立瓦斯流监测数据库,实现数据和图形的数据访问;建立瓦斯场分析数据库,将巷道瓦斯涌出量、瓦斯流量概率分布等进行统计分析,同时对巷道瓦斯流量样本进行特征值分析,通过与Auto CAD的交互式操作,将分析结果进行实时显示,从总体上了解矿井内各巷道的瓦斯涌出量及瓦斯流量分布状况。瓦斯流分析部分利用直方图法绘图,最小二乘法拟合曲线,χ2(k-1)分布函数对曲线拟合性检验,结合蒙特卡洛法及随机数的产生方法,对瓦斯流量进行随机取样,进一步验证曲线拟合性,最终得到瓦斯流量概率分布函数,从而确定每一条巷道的瓦斯流流量分布规律。Based on the mine ventilation system, we develop the visual form by using Auto CAD VBA, and implement data and graphics data access by establishing the monitoring database of gas flow. The database of gas field analysis is established, and the statistical analysis of the gas emission from the roadway and the probability distribution is carried out. At the same time, the characteristic value of the gas flow samples of the roadway are analyzed, and the results are displayed in real time by means of interactive operation with Auto CAD, which is provided for understanding the whole mine gas emission and distribution. The gas flow analysis section is drawn by histogram, the least squares fitting curve, the χ2（k-1）distribution function testing the result.Combining Monte-Carlo method and random number generation method, the gas flow is randomly sampled to further verify the curve fit, and finally get the gas flow probability distribution function, so as to determine the distribution of gas flow in each roadway.
