摘要
为搞清酸刺沟井田6#上煤层瓦斯含量分布规律,对实测煤层瓦斯含量数据和井田地质因素进行了综合分析。认为煤层埋藏深度是影响酸刺沟井田6上#煤层瓦斯赋存的主控因素,并建立了线性预测模型。预测结果显示,井田6上#煤层瓦斯含量由东部首采区2m3/t向西部未采区逐步增加至3m3/t左右;且酸刺沟井田6上#煤层处于瓦斯风化带内。
In order to study the gas content distribution law in 6# upper coal seam in Suancigou Mine,the paper has had a comprehensive analysis on the gas content data measured in coal seam and the mine field geological conditions.The result indicates that the buried depth of coal seam is the main factor which affects the gas deposit in 6#upper coal seam,and then a linear forecasting model has been established.The final predicted results show that in 6#upper coal seam,from the first-mining area in east of the seam to the unworked area in west of the seam,the gas content increases from 2 m3/t to 3 m3/t gradually;the 6# upper coal seam in Suancigou Mine lies in the gas weathering zone.
