摘　　要：通过对部分矿井同采区同翼同煤层回采工作面瓦斯涌出量、产量及其开采深度的研究,提出了预测高瓦斯高产工作面瓦斯涌出量的类比法,探讨了预测基本原理和步骤。并以淮南谢桥矿某回采工作面进行了预测准确性检验,结果表明,预测结果比实测值略小,相对误差在10%范围内,可为现场实际应用。The basic parameters which are used in tradition methods to fore.east the gas emitted from the face are. not gained from the same mine. So there are many uncertainty factors that cause the result unreliable. In this essay, the amount of gas, the output and the depth of the coalfaces are studied,which come from the same district, wining and layer in a coalmine. Based on these, the analogy method is mentioned and its＇fundamental and steps is given. In order to verify the method, it is used at a face in the Xieqiao Mine C13 - 1 layer of Huainan. And the results show that the forecasting value is smaller than the fact and the relative error is less than 10%. Thus, the method to forecast the amount of gas emitted from the face is feasible.
