大阳煤矿3号煤层瓦斯赋存规律研究

Study on Gas Occurrence Law of the No.3 Coal Seam in Dayang Coal Mine

为掌握大阳煤矿3号煤层瓦斯赋存规律,根据实测瓦斯参数,结合矿井地质情况,研究确定了瓦斯赋存影响因素,构建了3号煤层瓦斯含量和瓦斯压力预测方程,并绘制了瓦斯赋存等值线图,得到3号煤层瓦斯赋存整体上呈现"西部大,东部小"的分布,为煤矿防治瓦斯提供了参考依据。

In order to master the gas occurrence law of No.3 Coal Seam in Dayang Coal Mine,according to the measured gas parameters and combined with the geological conditions of the mine,the influencing factors of gas occurrence were studied and determined,the prediction equation of gas content and gas pressure in No.3 coal seam is constructed,and the contour map of gas occurrence is drawn.The results show that the distribution of gas occurrence in No.3 coal seam is"large in the west and small in the east",which provides a reference for gas prevention and control in coal mines.
