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。
As the basis of mine ventilation system design, prevention design and gas prevention and control measures, the accuracy of prediction will directly affect the reasonable determination of mine ventilation equipment, roadway section and gas extraction equipment and other parameters. The No. 1 coal mine is a new mine and the No. 3 coal seam is the first coal seam. The gas content data of this coal seam is quite scarce. Therefore, the quantitative theory is introduced to study the relationship between gas content and geological factors. Compared with the measured data, the error predicted by the mathematical geologic model is small, which proves the effectiveness of the method.
