摘　　要：为了研究煤矿瓦斯抽采主要因素及钻孔合理间距,分析了煤矿瓦斯抽采主要因素,得到了实际值和预测值拟合曲线,并建立了多元线性预测模型,然后建立了合理孔间距公式,采用数值模拟,模拟分析了不同孔间距的残存瓦斯含量变化曲线。研究为矿井瓦斯抽采钻孔合理布置提供了技术支持。In order to study the main factors of coal mine gas extraction and the reasonable distance between boreholes,the main factors of coal mine gas extraction were analyzed,the fitting curve of actual value and predicted value were obtained,and the multiple linear prediction model was established,then the reasonable distance between boreholes formula was established,and the residual gas content change curve of different hole spacing was analyzed by numerical simulation.The research provided technical support for the reasonable arrangement of gas extraction boreholes.
