摘　　要：针对煤层群赋存条件下的中保护层综采工作面瓦斯治理难题,通过大湾煤矿X10902工作面瓦斯涌出采用分源预测法进行分析,掌握工作面开采层、上下邻近层的瓦斯涌出来源及涌出特征,按分源治理的原则采取了有针对性的瓦斯治理技术,形成了一套立体式瓦斯治理体系,在该采煤工作瓦斯治理实践中取得了显著效果,工作面瓦斯抽采率超过90%,彻底消除了工作面瓦斯超限发生。Aiming at the gas control problem of the middle protection layer fully mechanized mining face under the condition of the coal seam group,Based on the analysis of gas emission in X10902 working face of Dawan Coal Mine by source separation prediction method,Master the source and characteristics of gas emission in working face mining layer,upper and lower adjacent layer,And according to the principle of source control adopted targeted gas control technology,Then a three-dimensional gas control system was formed,and remarkable results were achieved in the gas control practice of the coal mining work.The actual gas extraction rate of the working face is more than 90%,Thus completely eliminate the gas overrun phenomenon in working face.
