摘　　要：对钱家营矿5、7煤层2871回采工作面、2876E掘进工作面瓦斯抽放方法进行优化,通过对比试验,得出现场试验结果,再运用数值模拟软件对数据进行分析对比,验证优化方法的实际效果。最终确定回采工作面采用打交叉钻孔代替顺平钻孔,掘进工作面采用打高密度、多角度钻孔代替以前打低密度、单一角度钻孔,快速抽放瓦斯代替低速抽放瓦斯。Based on the Qianjiaying 5 and 7 coal seam in 2871 mining working face, gas pumping method of 2876 E heading face was optimized. Through a series of experiments on test site, then numerical simulation software was used for data analysis and comparison, in order to verify the optimization method of actual effect. Ultimately the mining working face with cross borehole replaced previous flat drilling, high density, multi angle drilling and fast pumping gas replaced the previous low density, single point of drilling and low pumping gas.
