山西某矿煤层瓦斯涌出量预测研究

Research on Prediction of Gas Emission from Coal Seams in a Certain Mine in Shanxi Province

为了对山西某矿煤层瓦斯涌出量进行预测,采用理论分析与现场实践的方法对煤层瓦斯涌出量进行分析。结果表明2021年、2022年预测瓦斯涌出量数值与实际瓦斯涌出量基本一致。在对煤层瓦斯涌出量进行预测时,需从煤层埋藏深度、围岩、井田地质构造、地下动水、矿井瓦斯区分等多方面分析煤层瓦斯状况。

In order to predict the gas emission from coal seams in a certain mine in Shanxi,theoretical analysis and on-site practice were used to analyze the gas emission from coal seams.The results show that the predicted gas emission values for 2021 and 2022 are basically consistent with the actual gas emission.When predicting the amount of coal seam gas emission,it is necessary to analyze the coal seam gas situation from multiple aspects such as the burial depth of the coal seam,surrounding rock,geological structure of the mine field,underground water flow,and gas differentiation in the mine.
