摘　　要：为了成功预测竹林山煤矿综放高瓦斯矿井大采高工作面煤层瓦斯涌出量,以主采3号煤层为主要研究对象,针对3号煤层以往开采情况,通过布设测点测量其煤层瓦斯含量和了解相邻矿井瓦斯含量,采用分源预测法、回归法及统计法等预测方法得到了3号煤层瓦斯含量的分布规律,并绘制了3号煤层的瓦斯含量等值线图。对矿井不同生产时期的瓦斯含量进行预测,得到了生产前期、中期及后期采区的最大绝对瓦斯涌出量和最大相对瓦斯涌出量,说明了竹林山煤矿各个时期均属于高瓦斯矿井。In order to successfully predict coal seam gas emission quantity on fully-mechanized large mining height working face in Zhulinshan highly gassy mine,the main mining No.3coal seam was identified as the main research object.In allusion to the mining situation of No.3coal seam,gas content of the No.3coal seam was measured and the gas content in the adjacent mines was understood through laying some measurement points,the distribution regularities of gas content in the No.3coal seam was obtained by use of separate source method,the regression method and the statistical method,and the contour mapof gas content in the No.3coal seam was drawn.The largest absolute gas emission and the maximum relative gas emission of district in the early period,the middle period and the later period of the production were gotten through predicting gas content in different production period,and it was proved that Zhulinshan Coal Mine is a highly gassy mine in different production period.
