摘要
为了准确掌握高瓦斯矿井巷道掘进时的瓦斯涌出量,对山西焦煤屯兰矿2#煤层401胶带巷、8#煤层203胶带巷在巷道掘进时的瓦斯涌出情况进行了考察。通过对考察数据的整理分析,找出了影响大断面、高瓦斯矿井掘进工作面瓦斯涌出的主要影响因素,提出了巷道掘进时的瓦斯涌出量计算模型。实际验证结果表明,该预测模型的准确率更高。
To accurately master the gas emission quantity in roadway driving of high gassy coal mine,the gas emission situation of the 401 belt roadway in No. 2 coal seam and the 203 belt roadway in No. 8 coal seam in driving,were investigated in Tunlan Coal Mine of Shanxi Coking Coal Group. Based on the collection and analysis on investigation data,the main factors of influencing gas emission on driving face with large section and high gas concentration were found out, prediction model of gas emission in roadway driving was also put forward. Practices have showed that the prediction model can achieved higher accuracy rate.
