摘要
煤层瓦斯含量预测资料,作为矿井通风系统设计、防突设计及瓦斯防治措施的依据,预测的准确度将直接影响矿井通风设备、巷道断面、瓦斯抽采设备等参数的合理确定。马依西一井为新建矿井,而3#煤层为首采煤层,关于该煤层的瓦斯含量资料相当匮乏,因此引入数量化理论对瓦斯含量与各地质因素关系进行研究。用数学地质模型预测的结果与实测值相比较,误差较小,证明了该方法的有效性。
Forecast datum of coal seam gas content, as the basis for design of mine ventilation system and coal and gas outburst preven- tion and control measures, the prediction accuracy of the forecasts will have direct impact on mine ventilation equipments, roadway sec- tion, gas extraction equipments and other parameters. Mayi West No. 1 Mine is a new mine, 3# coal seam as the first coal layer, gas content datum are very scarce, so the paper introduces the quantitative theory to study the gas content and geological factors. Compared the results of mathematical geology model predictions with the measured value, the error is smaller, which proves the validity of the method.
